Promaster Dive Green Dial

The Promaster Dive wears its tool-watch credentials openly, with a blackened 41mm stainless steel case built for serious underwater use. Citizen's Eco-Drive movement runs on light, eliminating the need for battery changes, while the unidirectional bezel and diver-spec water resistance keep it functional well below the surface. A disciplined, no-compromise piece for those who use their watches as instruments.
