How do I adjust my watch to the perfect size?
With so many different designs, there’s definitely the perfect model for every wrist size. Our watches with linked 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, you’re sure to find what you need at your trusted specialised watch or jewellery dealer.
What is delivered in the package contents?
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 cork that comes with our watches and Bandlets is reversible and inscribed on both sides respectively with the sentence in German - “So einzigartig wie du”, as well as English - “As unique as you”.
For all models with linked bracelets, we additionally send the matching extension links including tools free of charge. In this way, you can individually adjust your personal piece of nature and immediately start wearing it. :)
How do I get my watch running?
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 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 operation.
If you have an automatic or solar watch, you’ll have to first wind it up or charge the battery.
Core Features
Metal-Core Technology
Our Metal-Core technology has been especially developed in order to make our watch constructions with natural materials even more durable. With timepieces that have this special type of construction, the clockwork is encased in an airtight metal jacket that guarantees a waterproofness of up to 5ATM.
We thereby unify the best of two worlds: natural diversity of materials & the longevity of our designs.
koa wood
A piece of Hawaii for your wrist! Koa wood comes from the South Sea paradise and is one of the most popular woods in the world due to its unique grain. In its homeland, the wood is used to make surfboards and ukuleles, for example. The detailed surface texture, combined with golden to reddish brown colors makes every object made from koa wood a real eye-catcher. That's why you can find unique watches and jewelry made from this precious raw material - eye-catching accessories for a special look!
Chronograph Watch
Chronographs combine precision with a sporty look. On top of that, these watches have an integrated stop function, which makes your everyday life easier! The operation is very simple: there are two buttons on the side of the watch case. The upper one starts and stops the measuring process, and the lower one resets the stop hand to zero. Get your multifunctional timepiece and let it accompany you through your busy everyday life!
316L Stainless Steel
To protect our wood and stone materials from breakage and external pressures, we combine them with 316L stainless steel, also known as "surgical steel". The composition of iron, chromium, nickel and molybdenum makes it particularly robust and corrosion resistant.
The shiny surface provides a flawless look and can be easily coated with other colors. This is our secret ingredient that guarantees your unique piece nature has a long and exciting life!
