Some watches ape the diver aesthetic without delivering diver-quality features. That's not a problem Hamilton's Khaki Navy BelowZero Titanium. Its rugged titanium case is equipped with a helium escape valve and is water resistant to 1,000 meters for deep water adventures. It sits on a rubber strap and is powered by a H-10 3-hand self-winding movement, with a generous 80-hour power reserve.
