Hamilton's Frogman was originally created for the U.S. Naval teams of the same name, able to withstand the rigors of harsh maritime missions. This modern incarnation retains the toughness of the original models with a stealthy contemporary aesthetic. The stainless steel case is given a black PVD coating, which is matched by the textured black dial, black rotating bezel, and wavy black tactical rubber strap. It's powered by an H-10 automatic mechanical movement, water resistant to over 900 feet, and has a robust protector for the screw-down crown.
