The epitome of sustainability! The watches from our Automatics collection operate on kinetic energy: the movement of your wrist. You can also wind the movement with the crown on the side. So you'll never need a battery for your watch again. Inside the movement of this Carbon Silver rotates a rotor that converts the energy from the movement of your wrist into energy that makes the watch run. The Carbon Silver has a silver skeleton movement, so you can watch the entire movement spinning, both from the front and back. This wood watch has a diameter of 44mm and is made from American ashed maple wood. This gives the wood a unique and vibrant smokey appearance. The front and back glass is made of scratch-free mineral crystal, and the stainless steel details on the dial and in the bracelet are silver. The time is indicated by Super-Luminova hands. The strap is easy to adjust to your wrist with the free tool provided. This men's wrist watch comes with a 1-year warranty.
