Each JORD watch is hand crafted and made from raw materials. The JORD brand values sustainability, efficiency, and experiential living. Their watches are made from 13 different woods including Acacia, Bamboo, Ebony, Golden Camphor, Koa, Kosso, Maple, Olive, PurpleHeart, Walnut, Rosewood, Sandalwood, and Zebrawood. My watch has a self winding automatic mechanical system. If you turn over the watch you can see all the gears working and it is fascinating! The picture below does not do the mechanics justice, you will have to buy your own to see how intricate the gears are. The face of this watch is covered in Sapphire Glass which is known for its durability and transparency.
