Inspired by the elusive Virginia class attack submarines, the US-744X is a tier-one diver’s watch. Machined from solid Grade 5 Titanium, the 45mm x 16mm case and bracelet weigh only 6.5 ounces combined. A sleek multi colored brass dial incorporate tritium-gas tubes in lieu of numerals to provide readability in low light conditions. The hands are also equipped with tritium-gas filled tubes making them easy to read underwater. The second hand smoothly sweeps across the elegant dial giving the US-744X a very classy feel. A feature typically found on higher end watches.
