With a water resistance of up to 100 bar (1000 m) and equipped with a helium escape valve, the Khaki BeLOWZERO is perfect for the most intrepid deep-sea adventures. The convex sapphire crystal offers high-performance protection during underwater exploration, while its bright yellow rubber strap, combined with the 46 mm brushed titanium case, evokes the solidity of a yellow submarine. This Hamilton watch is a classic nautical model designed for pioneers of marine activities.
