Water resistant up to 100 bar (1,000 m) and equipped with a helium escape valve, the Khaki BeLOWZERO is perfect for even the most daring of deep water adventures. The convex sapphire crystal offers high-performance protection during underwater exploration and the black PVD treated 46mm stainless steel case is reminiscent of the bulk of a submarine. This Hamilton is a nautical classic designed for marine pioneers.
