This watch is made of French HCP American alligator leather, the top is American alligator bamboo leather, and the bottom is round alligator leather. The core material is a composite rubber core material. The original intention of the product design is to make this watch strap have a texture and a sense of heaviness, so the men's version (products above 18mm) is thicker than the conventional watch strap. The stitching of this watch strap is relatively thick and more atmospheric, and the head is beveled to make the overall version more beautiful.
