The strap is made of good quality canvas, the same rugged material used for making sails, tents, backpacks and other outdoor/ military items that need to withstand the elements. With the canvas on both sides and the edges rolled over, the strap is comfortable and sturdy on the wrist. Over time the softened canvas and frayed edges around the strap holes add much character to both strap and watch.
