Ultrarun Collection: High-Class Men's Watches in Wood and Stone

Movement and exercise can sometimes prove to be limiting, don’t they? No problem, thanks to high-quality automatic movement, our unique watches have a running time of 42 hours. After that, a single step is enough to start it up again. The renowned Miyota 8N40 movement from Citizen is known for its precision and is guaranteed to never let you down.

Like many Holzkern designs already, the wooden elements are protected from moisture by our innovative Hydro-Defense Technology. This time, however, we've also added a resin coating to the marble links, making these one-of-a-kind timepieces even more durable! With scratch-resistant sapphire crystal, your watch is perfectly protected from any environmental elements and water-resistant up to 10 ATM.

Another exciting feature is the innovative markings on the dial. Spikes, hands, grooves and circles complement each other to create a lively interplay of shapes, which is completed with perfectly coordinated color accents. The laser cut-outs also allow a deep look into the skeleton automatic movement, creating an exciting contrast with the underlying rock.
