Our watches are held to the highest standards of craftsmanship, reliability and quality. Each of our products is unique and original. All watches are handcrafted using earth-friendly wood sourced from ancient Asia. A variety of materials are used in the production process, including teak, ebony, maple, and even bamboo. These woods are hand-selected by skilled craftsmen to ensure the superior quality of our wooden watches.

It's okay to get a little wet, but you can't use it while swimming or showering. Wood products are sensitive to moisture. 3. If you wipe it occasionally, the colors will become more vivid. 4.
