What sets the US-744X apart from all other diver class watches on the planet, is its bold 45-hour automatic power reserve counter, day and date sub counters at nine, six and three, respectively.
Continuing throughout the design is a thick 5.5MM sapphire crystal. Tritium tubes are hand applied on both watch hands and at all hour markers.
There is a sweep second hand to ensure perfect timing.The sophisticated design features a screw-down crown with locking unidirectional rotating bezel on top of a (CNC) computer numerical controlled, integrated titanium, and carbon fiber watch case.Its tapered watch lugs house specially made hex-nuts pins for a strap or its custom-built titanium bracelet. Turn it over and, you will notice a guilloche rotor on its Grand 6R20 29 jeweled automatic movement through a 3.5 mm sapphire exhibition case back.
