Crafted of stainless steel with super-hard coating, this superbly functional diver’s watch includes a sapphire crystal with anti-reflective coating on the inner surface, as well as a screwdown crown and caseback. The bracelet is designed with mirror polish center links to match the sophisticated case design, which follows ISO standards for scuba diving to depths of 300 meters while maintaining a slim profile. 300m Water Resistant
