Handcrafted from Sustainable Hawaiian Koa

Timepieces of Hawaiian Royalty

Hawaiians have long revered Koa wood as a sign of royalty, so we've created timepieces fit for a king. We only harvest naturally-fallen Koa trees, to not disturb it's beautiful lifecycle, and craft them into watches that create a sustainable, positive impact on the Earth.

A Tribute to Nature's Beauty

Koa: The King of Woods

Crafted with Authentic Hawaiian Koa Wood: Each EcoKoa watch is carefully handcrafted from genuine Hawaiian Koa wood and a custome Stonewashed Steel we developed over 2 years.

The Story Behind Our Hawaiian Koa Wood

Ancient Hawaiians used it to sculpt images of their gods. It was the wood of choice when natives built outrigger canoes for their kings and queens. And today - centuries later - it remains one of the finest textured woods in the world. It is Koa, and it is Hawaiian royalty.
