This watch strap has a flat interface, and the surface of the strap is rounded with a beveled shape. The overall shape of the strap is full, showing the three-dimensional sense of the strap. The surface of the strap is made of JU crocodile leather, which far exceeds the standards of luxury groups in terms of performance indicators such as waterproofness, sweat resistance, and wear resistance. It is 10 times the EU standard and 3 times the luxury group standard. The bottom leather is made of professional waterproof top layer calfskin, and the half-edge process makes the overall texture more advanced.
