As a diver’s style watch the Alpha is water-resistant to 300m and has an AR-coated (three-layers according to Nite) sapphire crystal. Another really nice feature is the use of a blue ceramic insert in the unidirectional rotating bezel. Note as well the use of a tritium gas tube as the lume pip at the 60-minute marker on the bezel. Inside the watch is a Swiss Ronda caliber 715Li quartz movement and “Li” stands for lithium-ion, meaning that the movement has a 10-year battery life.
