FAQ

Our team makes every effort to ensure that your piece of nature arrives as quickly as possible. Models that are in stock will usually be given to our shipping partners within one workday once you have ordered.

The delivery time of our models can always be found on the respective product page, and also in your order confirmation. You can be sure that models which are in stock will be delivered within a few workdays. In case your model isn’t in stock due to high demand, you can pre-order it and we’ll send your model within the stated delivery time.

Incidentally: A gift card purchased on our website will be sent to you within a couple of hours via email. It’s a nice and original gift solution when you need it quickly! :)

In case your order contains several products with various delivery times, you can choose from the following options during the order process:

• Collective shipping - for the sake of the environment, all models will be shipped together as soon as they are in stock and you’ll receive a notification via email.
• Partial shipping - all items that are in stock will be shipped in advance.

All shipping costs are covered by us regardless of which option you select.

You can check on the status of your order in your customer account or as a guest.

In addition to that, as soon as your items have been sent, you’ll receive a confirmation via email with all necessary information, as well as a link to track your model up until delivery. Don't forget to check your spam folder, too. :)

Of course, an exchange is fine as long as the model is unworn and the return period of 24 days is adhered to.

It's that simple:

1. Please fill out our cancellation form.
2. Send the product with the completed cancellation form & copy of the invoice in the original packaging to:
   Holzkern - Time for Nature GmbH
   Autokaderstraße 33/11.3
   1210 Vienna
   AUSTRIA
   
3. Order the desired model anew in our Online Shop - this is necessary because we need a separate invoice for each product.

As soon as we receive your return, the amount will be credited back to the original payment method within a maximum of 10 working days. If you ordered on account, the payment provider Klarna will be informed about the credit.

Important: Please note that jewellery purchased in our stores can only be canceled and exchanged directly in our stores.

We have several Holzkern stores where our unique pieces can be admired and tried on.

Our stores are located all over Germany and Austria. You can find your nearest store using our store locator. Our store team looks forward to meeting you and will be happy to advise you. :)

On top of that, we have multiple retail partners in Germany, Austria, the Netherlands, France, Belgium, Luxembourg, Italy, Spain, Portugal, Switzerland and more - click here for a full overview.

To be sure that the model you’re interested in is in stock, we recommend contacting the respective store beforehand.

Of course, you can also order several models from our online shop as a selection to view (and try on) at home and simply ship the models you don’t want to keep back to us for a withdrawal within the 24-day refund period.

In order to get your watch up and running, remove all protective foils first. With a Quartz movement, you can directly set the time by removing the plastic stopper and turning the crown, which is the small calibration wheel on the side of the case. As soon as you’ve set it to the correct time, push the crown gently against the case and your watch will begin to run.

If you have an automatic or solar watch, you’ll have to first wind it up or charge the battery.

Of course you can return your model and we will refund the money if, contrary to expectations, you don't quite like it. :)

Please make sure that the model is still unworn and that the return period of 24 days from receipt is adhered to.

Please send the goods together with the completed cancellation form to our address: Holzkern - Time for Nature GmbH, Autokaderstraße 33/11.3, 1210 Vienna, AUSTRIA.

As soon as we have received your returned goods, the amount will be credited back to the original payment method. If you ordered on account, Klarna as the payment provider will be informed about your credit.

You may find another model in our online shop that suits you better - with over 800 designs, there is usually something for everyone.

Since we want to continue to improve our products, we are always happy to receive feedback from you. :)

Important: Please note that jewelry purchased in our stores can only be returned directly to the store.

The special thing about our products is that we work with natural materials. Just like every tree or stone, all of our models are genuinely unique thanks to the grain, color and structure of the materials. What you receive is a truly one-of-a-kind piece - indeed, your own personal piece of nature. :)

That’s why we always make an effort to incorporate different lighting situations and a variety of models in our images, so that you can receive the most realistic impression possible of how your model may look.

Our team is constantly working on amazing and innovative products, that’s why we’re regularly expanding our selection with waterproof products like these:

• Watches
• Bandlets
• Jewelry

These products can be worn while swimming, showering and bathing.

Since we work a lot with natural materials like wood, our other models are generally not waterproof.

Wood can become altered if there is too much contact with moisture, water or alcohol (perfume). We therefore recommend that you remove your piece of nature before showering/swimming/bathing in order to enjoy it for the longest possible time.

Spray water and perspiration don’t present a problem and, during normal daily use, you need not worry at all. :)

All of our models are already incredibly unique thanks to their handcrafted production and the use of natural materials.

In case you want to add a personal touch with a custom engraving, we recommend that you seek the professional services of a watch maker or jeweler. We currently don’t offer this service in-house.

To add an engraving to our watches or Bandlets, we recommend using the clasp of the linked bracelets. Because the designs of our jewelry pieces are so diverse, we recommend a personal consultation in the workshop of your choice. We are currently working on new jewelry collections that have more space for custom engravings.

We don’t recommend engraving our sunglasses because the construction of the frame could become compromised. Due to the natural materials used, they are already entirely unique!

Holzkern has grown and developed a lot in the past years. It all started with wooden watches. Since then we have expanded our product range enormously and are making use of natural materials from all over the world. And: In order to bring natural diversity to the forefront, we’ve created a new logo design.

The delicate shape allows for different interpretations, which are reflected in nature and the materials we use. The modern design stands for one thing above all: uniqueness!

As far as our products go, the exchange of logos will be done step by step. So your desired unique piece will either have the Holzkern lettering, the original tree rings logo or the new logo. Ultimately, the most important thing is that your Holzkern model reaches you in the highest quality as always and that you enjoy it for a long time.

We ship our products worldwide - shipping is free of charge for you. :)

Our team is very fast, which is why the delivery time for products in stock* is usually only a few working days.

With some shipping providers (DHL and the Austrian Post), shipping is already climate-neutral without any additional costs for you.

*For products that are not in stock, you will find the delivery period on the respective product page or in the order confirmation.

The delivery time of our models can be found on the right side of each product listing, next to the product photos.

As soon as your order is on its way, we will notify you about the shipment. :)

It is our greatest goal to offer our customers the widest possible variety. That's why all models are only produced in small production series and are therefore out of stock from time to time.

To make sure you are on the waiting list and receive your model in the next production series, is necessary to pre-order the desired model. When you place your order, the amount will normally be deducted immediately, depending on the selected payment method.

As soon as your ordered model is back in stock, we will of course send it to you immediately. We want to keep your waiting time as brief as possible and will also send you the shipment tracking via email after dispatch so that you can track your model until delivery.

A discount code has either reached you via email, post on social media or you have found it directly on our website. Our discount codes and promotions are subject to certain conditions and cannot be combined with each other. This means that they cannot be used on sale items.

You can redeem a discount code directly during the checkout process in the appropriate field by clicking on 'Apply discount code'. It will then appear in the shopping cart overview and will be applied directly. :)

If the discount code does not work, you can check the following again:

• Have you fulfilled the conditions (e.g. minimum order value, minimum order quantity)?
• Is the model part of our regular product range? (i.e. not part of the outlet).
• Did you enter the code in the correct field (discount code) and press 'apply'?
• Is the discount code from a trusted source and still valid?
• Is the discount code applicable to your desired models? e.g. accessories are often excluded.
• Have you correctly differentiated all 0's and O's and made no other typos?

If you can answer YES to all these questions, then the discount code itself should be applicable.
If there is still a problem, please contact us directly via the service form. Please send us a screenshot of your shopping cart, discount code and error message and tell us where you found the discount code. We will then try to find a quick solution. :)

Our gift cards are in XXXX-XXXX-XXXX format and can be entered as a numerical code directly in the "Enter Gift Card Code" field at the checkout. You can use it as an alternative payment method to complete your order.

Our gift cards are only redeemable in our online shop. We don't think that's a disadvantage – on the contrary: here you have the largest selection of all our models and can take as much time as you want to browse! :)

If the gift card does not work, you can check the following again:

• Have you typed the numbers correctly and differentiated all 0's and O's?
• Do you still have credit available on your gift card?
• Did you use the gift card in the correct field?

If you answered YES to these questions, but it still doesn't work, then please contact our Customer Support right away. Send us a screenshot of your gift card, your shopping cart and the name of the person who purchased the gift card.

If your gift card value is not completely used up on an order, the remaining credit stays and can be used for a future order. Our gift cards have no expiry date and can be used for any product or service that we offer. :)

If you wish to return or exchange an order made with a gift card, the amount will be credited back to the gift card and it will be reactivated. It can then be used for a future order.

Only one discount or promotion code can be applied to an order - you have to decide which one you want to use. :)

You can use up to 9 different gift cards for one order. You can also combine vouchers - for example 5 gift cards for €20 each and 1 discount code can be used for one order. :)

You can check the status of your order here.

If your order contains several products with different delivery times, you can choose between the following options during the ordering process:

• Collective delivery - for the sake of the environment, all models will be sent together as soon as they are in stock and you will be notified by email about the shipment.

The shipping costs are covered by us, regardless of which option is chosen.

It's that simple:

1. Please fill out our cancellation form.
2. Send the product with the completed cancellation form & copy of the invoice in the original packaging to:
   Holzkern - Time for Nature GmbH

Our team will do everything to ensure that you receive your unique piece of nature as quickly as possible and that you are absolutely happy with it.

As we process your order in the shortest possible time and ship models that are in stock extremely fast, it is unfortunately not possible to make any changes afterwards.
Once your order has been shipped, you can try to change the address directly with the shipping partner:

UPS
With UPS you can change the address yourself directly via your tracking link. Please note that a scan must already have taken place in the destination country and in some cases it is only possible after the first unsuccessful delivery attempt. And please also note that in order to do this, you need to have a customer account.

Post, FedEx
Please contact the respective shipping company directly with your correct address and the shipment number you received by email.

We ask for your understanding that we cannot promise anything here.

If it is a pre-order - i.e. a model with a longer delivery time - please contact our Customer Support using the service form. They will be able to help you in the best possible way.

We are very sorry that something is not as it should be with your selected model. Naturally, we want to help you in this case and would therefore ask you to contact us directly via the service form.

Please describe as precisely as possible what the problem is and, if possible, also send us a photo and the order number. That way we can get the best possible picture of the situation and offer you a quick solution.

In this case, please check which model you have and which movement (automatic, solar, quartz movement) is installed in your watch. You can find this information on the website for each model.
If you have a solar or automatic watch, please try restarting the watch. You can find out exactly how to do this in the instructions on the website. If you have a quartz watch, it may simply be that the battery is flat and needs to be replaced. You can have this done at a specialist shop or jeweler that you trust.

If you still have problems, please contact us using our service form and we will find a suitable solution for you.

If you have taken care of returning items to us, you should have received a tracking number from the chosen shipping company. With this number you can track the parcel on the carrier’s website.*

Once your return package has arrived and been processed, you will receive an email notification.

*Returns from Germany sent by DHL will be forwarded from Kiefersfelden to us in Vienna - this can take up to two weeks.

In order for us to process your package as quickly as possible, please include a copy of the invoice and a note stating the reason for the return in the package.

In case of a cancellation, please also enclose thecancellation form.

To ensure that your returned models are protected in the best possible way during transport, please be sure to return them in their original packaging. This means, depending on the product, in the wooden box, the kraft paper case or the additional packaging box.
Finally, choose an appropriate package size and fill the empty space with bubble wrap or paper so that your model is not thrown around during shipping. Please also make sure the parcel is properly closed and sealed on the outside.

This way, your returned models are well protected and will arrive safely.

Once you have received the email that the package is with us and has been processed, it will take a maximum of 14 working days for the amount to be refunded to the original payment method. You will also be notified of the credit by email.

When you take your watch out of the box, the crown is usually set with a small plastic spacer. This is to prevent the battery from being used before the watch arrives, especially in the case of quartz movements. In order for the watch to start running, please remove the stopper, turn the dial to the desired time and then carefully push the crown into the case. Your personal piece of nature is ready for use.

The exact battery life is indicated in the instructions, which can be found on our product page of the respective model when you scroll below the sample pictures. If you notice that the movement is becoming irregular, it means that the battery needs to be replaced. You can easily have it replaced at your nearest watchmaker or jeweller. We can also replace it in one of our stores.

If you’ve decided on a watch with solar movement, starting it up works a little differently. In this case, there is an inbuilt battery that is recharged via the energy of the sun or a light source.

In order to charge your solar watch, remove the protective foil from the glass and charge it for a minimum of 5 hours in direct sunlight. Particularly in months with less sunshine, the watch should be charged under a lamp (at a distance of 20cm) for 60 hours (30W lightbulb/6W LED/Lumen 375) because the sunlight is a little bit too weak to recharge the battery.

Please note that your solar watch shouldn’t be exposed to excessive heat (e.g. the blazing midday sun) in order to avoid damage. As soon as your model is recharged, the battery will last for at least 4 months without the need to recharge your watch again. When the seconds hand begins to tick in 2-second intervals, it’s a sign that your timepiece needs light again and should be recharged.

In case your model has a variety of functions, like e.g. a date display, a dual time display or a chronograph, get to know these functions in advance in order to maximize the full potential of your watch.

Your automatic watch works somewhat differently to a watch with Quartz movement. Because you’ve chosen a watch with mechanical movement, there is in this case no inbuilt battery and you’ll have to first give your model a little help to get it up and running.

Before you wind it up, make sure that the crown is in the normal position, which means fully pressed against the case. In order to get your watch operating, turn the crown 40 times in a clockwise direction and your watch will run for approximately 42 hours. If you wear your watch within this time, the running time is extended because the clockwork will be automatically wound up via the motion of your body.

With so many different designs, there’s definitely the perfect model for every wrist size. Our models with link bracelets can be easily adjusted to any preferred length.
Additional bracelet links and the necessary tools are enclosed free of charge so that you can immediately adjust your model to your individual wrist size and wear it.
The leather watch straps and vegan alternative straps in our product range come in industry-standard sizes. For particularly short or long watch straps, please see a (specialised) watchmaker or jeweller near you.




Here you can find video instructions for links with pins, clasp pins and spring pins. :)

You will hardly find watches or Bandlets that are as comfortable to wear as ours. The wood is characterized by its lightness, which makes your model very comfortable on the wrist.

We use selected hardwoods for our products, which are carefully checked beforehand and give our customers a lot of pleasure for a long time. Please note, however, that wood does not have the same resistance as metal, for example, and may show changes when subjected to external forces.

As with other pieces of jewellery that you want to enjoy for a long time, you should handle our models with care and take them off, for example, for manual work, sports or before going to bed.

Our models do not require any additional or special care, because wood becomes even more beautiful and smoother with time. However, if you still want to treat your piece of nature, the wooden elements will appreciate a little wood oil or wood balm to make them shine again. The best product for this is our special care balm, which you can find in our accessories shop.

Clean your model first and then rub in some of the chosen product with a clean cotton cloth in gentle motions. Let it soak in for a few minutes and then remove the excess product with a dry corner of the cotton cloth. Your model will be as good as new! :)

Every single Holzkern product is delivered in a high-quality solid wooden box in which your piece of nature can be safely stored. The wooden box is lined with cork, which optimally protects your model during transport or storage.

The removable cork piece in the wooden box in which our watches and Bandlets are delivered is reversible. On one side you will find the German sentence “So einzigartig wie du”, and on the other side you will find its translation to English: “As unique as you”.

For all models with linked bracelets, we additionally send the matching extension links including tools free of charge. This way, you can individually adjust your personal piece of nature and immediately start wearing it. :)

In principle, our models don’t require any special kind of care because the wood and marble will only become shinier and smoother over time.

Occasionally, the wooden elements will appreciate a little care in order to get them shining again. For this, a special polishing cloth can be found in our Accessories Shop.

Beeswax or natural wood oils are also totally fine for use. :)

We currently offer a selection of letters as pendants in gold and silver-colored stainless steel with shimmering white nacre. However, we are planning to offer more designs in the future so that our customers have even more combination options for their unique piece. :)

Your necklaces, bracelets, earrings and rings don’t need any special maintenance. If you like, you can wipe them with a damp cloth from time to time so that they stay nice and shiny.

Because our models made with untreated wood* are not waterproof, the wooden elements can be given some care every now and then. For this, we recommend using our special care balm. You can also use beeswax or natural wood oils if you like. :)

*For some of our collections, we use so-called HydroDef technology, in which the wooden elements are additionally covered by a clear layer of synthetic resin. This makes them waterproof, just like our models with stone and nacre elements.

It’s always best to take a look at the product description in the specifications for your model. There, you can find information on which materials were used and whether they are water-resistant.

Our jewelry is delivered in a small wooden box, fixed on a piece of cork. This way, your model is not only optimally protected during transport, unpacking is also a special experience. The wooden box with a magnetic metal clasp not only looks great, it’s also perfect as a travel companion or for storing your unique pieces.

Due to their size, some models from our men's collections are packed in the same boxes as you may already know from our Bandlets.

Our rings are available in a range of different sizes. If you don’t know your perfect size, we have instructions on how to measure your ring size.

Alternatively, you can try on different sizes in one of our stores, or order several different models from our online shop as a selection to try on at home.

We use industry standard lengths for our jewellery range. The exact dimensions and lengths of the various collections can be found on the respective product page under specifications.

With our extender, you can lengthen your bracelets and necklaces from our women’s jewellery collections by up to 8cm. This allows you to wear your necklaces at different lengths depending on the occasion, or you can wear several necklaces to create your own personal layered look.

We use high-quality ion plating methods on the stainless steel in our products. We can guarantee that it meets all the requirements of everyday life.

For our women’s jewelry, we use a different technique. For a particularly elegant look, we refine the 316L stainless steel with genuine 24k gold, rose gold or platinum plating.

For our men’s collections, we use 316L stainless steel. In the process of ion plating, higher grade metal layers (e.g. cobalt) are applied, which results in different colorings. This is the same technique as you already know from our watches and Bandlets. This also means that all of your models will fit together harmoniously, regardless of whether you combine watches, Bandlets or individual pieces of jewelry.

Small hint: On our jewelry page you can search for specific materials, colors and styles.

Our handbags are designed in such a way that the strap of your Uniqase can easily be removed and replaced by means of a trigger hook. This means that you have countless ways of carrying your own unique piece.

In addition, the leather straps are adjustable in length and can be combined with all kinds of different styles. From messenger bag to shoulder bag, your companion can adapt to all of your individual requirements.

The vegan alternative made of metal is available in a fixed length and has a classic, elegant design for a timeless look.

As always, the exact lengths and dimensions of the different straps and models can be found directly under the product pictures in the specifications.

Our models are made from natural materials, and we have sealed every design with a special coating that protects your bag from moisture and keeps it beautiful for a long time. This means that your own unique handbag is prepared for every type of weather and occasion.

Like many fashionable companions, your bag is not 100% waterproof, and the contents could get wet due to heavy rain or if you accidentally drop it into water. However, unless you’re going to be walking through heavy rain regularly, you don’t need to worry: Every model is splash-resistant and can of course be worn in everyday life without worries.

When you’re not wearing your Uniqase, we recommend storing it in the cotton bag included with delivery. This way it is optimally protected and will bring joy for a very long time.

Each Holzkern Uniqase is delivered in a cardboard case. Inside, your piece of nature can be found safely kept in a high-quality cotton bag that provides extra protection.

You can find out which straps are included with your model in the specifications under the product photos.

Our bags made from wood and stone are truly unique. Because they are made from natural materials, they not only impress with their design, but also meet all the requirements for everyday use. The inside of each bag is lined with Washpapa (a vegan leather alternative) or leather, and can be securely closed with a magnetic clasp.

The straps are made of metal or leather and can be removed on both sides or swapped in order to create a new look.

When you’re not wearing your Uniqase, we recommend storing it in the cotton bag included with delivery. This way it is optimally protected and will bring joy for a very long time.

If you want to clean or care for your unique handbag, we recommend using a dry cotton cloth and gently rubbing it over the affected area. For more stubborn dirt, you can use a damp cloth.

Wood is a natural material that can change over time. This means that you will always have a unique companion with character, and with the help of a little wood oil or wood balm it will always look nice and shiny.

Produced in small series, we have something for every occasion: Our Uniqase designs have enough space for your essentials and can be worn as a cross-body bag, on your shoulder, or held in your hand.

The inside of each bag is lined with Washpapa (a vegan leather alternative) and protects the contents in a large compartment.

You can find the materials, dimensions and lengths of the different designs on the respective product page in the specifications.

Each of our models has a magnetic clasp which closes the bag securely. The magnets are particularly strong and durable, which means you can safely carry all your favorite items with you. To open the clutch, gently push upwards from the side - it’s that easy!

We manufacture our glasses exclusively without prescription. Of course, you can have your optical lenses fitted into our frames to match your prescription. The best thing to do would be to seek advice at an optician's of your choice. :)

Due to the high protection factor of UV 400 and the anti-glare category CAT3 which all our sunglasses have, they are also suitable for people with sensitive eyes, and for people who wear contact lenses. The choice of different polarized models, colors, and gradient of lenses offers additional comfort.

Our sunglasses are made exclusively with hardened TAC lenses. TAC, which stands for "Tri Acetate Cellulose", is an extremely light, robust material that is particularly popular in the sunglasses industry for lenses and also frames. It is obtained in a complex process from natural fibers such as cotton. The TAC lenses are composed of several layers to ensure optimal protection for your eyes and, at the same time, increase wearing comfort:

• an inner and outer protective layer protects against scratches and other damage
• a UV 400 protective layer protects against UV-B and UV-A rays
• a category 3 anti-glare layer gives the tint level

The lens colors grey, brown and green are flattering for every type and offer a particularly high glare protection due to the tinting. The tint of our lenses is classified as CAT3 - which means that the glare protection (0-4) allows you to wear the glasses on a bright summer day, a walk on the beach, but also on the slopes.

In addition to these lens features, we also have models with a colour gradient, which are special eye-catchers. You can also find mirrored glasses to be perfectly equipped for sunny adventures. :)

Our Holzkern sunglasses are delivered with a microfiber cleaning cloth in a microfiber-lined kraft paper case. To protect your glasses, we recommend storing and transporting them exclusively in the case. This way your accessory is protected from scratches and other damages.

To enjoy your model for a long time, it should always be stored in a suitable case. Nevertheless, after a while, fingerprints and dirt will inevitably accumulate on the lenses. To remove them, we recommend a suitable eyeglass cleaner to protect the lens surface. For quick cleaning on the go, it is enough to gently clean your lenses with our microfiber cleaning cloth.
In case of more stubborn dirt or dust residues, you can dampen one corner of your cleaning cloth and clean your lenses with it.
However, please avoid direct contact with water, as this can change the condition of the wood.

As usual, we produce in small series to offer a wide variety. Therefore we have again deliberately manufactured some designs as single pieces while other models are available in several colour variants.

All details and dimensions are listed in the specifications. Here you will also see recommendations to find the best model to emphasize your face shape.
The frames of our sunglasses are made of different materials to ensure that there is a model for every taste!

Make a statement with our acetate frames in different colours! The material makes them particularly stable and robust to be a faithful companion in everyday life.
Our models with metal frames have adjustable nose pads for the highest possible wearing comfort. Please consult a trained professional for the adjustment.
Our models with wood and metal frames are particularly versatile and a perfect combination for an extravagant look.
No matter which material - there will be a unique piece that flatters your face. Under the specifications you will find recommendations for which face shape the model is particularly suitable for.

All our designs are splash-proof.

Due to the wooden elements in all our designs, increased water contact should be avoided, as wood is a natural material that can change with extensive contact with liquids.

To enjoy your sunglasses for a long time we recommend to take them off before going swimming - this way they also can't get lost! ;)

Our sunglasses are made of TAC lenses that provide excellent sun protection for many everyday activities. With UV protection 400, the lenses protect against UV-B and UV-A rays, which allows you to wear the glasses both on the beach and on the slopes.
The anti-glare category indicates the degree of tinting, which is related to the incidence of light. 0 indicates the highest light incidence and 4 the lowest light incidence. The given protection is to be understood exactly the other way around: 0 means the least protection and 4 the maximum protection. Fulfilling the so-called CAT3 (i.e. glare protection category 3) our glasses offer excellent protection even for sensitive eyes without being too dark.
Additional protection is provided by the different colors in which our models are available: Gray, brown and green lenses are considered particularly comfortable to wear and are recommended by many experts. :)
