Koa, Mother of Pearl - 23549Our Koa Wood Watches are made with solid Koa from our own private stock harvested on the Big Island. We hand selected the Koa for its beautiful color and grain patterns. No veneers. Solid Koa. The Koa will not fade or darken over time. Instead the patina gets richer with wear. The battery will last up to two years and can be easily replaced. Our wood watches are splash resistant and should not be submerged in water. Our partner Frances Lau in British
