Constructed entirely from recycled polycarbonate, the new Citizen Promaster Dive combines beauty and function in a timepiece that channels the ocean’s spirit while helping you explore its depths.

This new Promaster Dive has a full-lume dial and a Super Titanium case with a diamond-like carbon coating—a material 40 percent lighter than stainless steel and five times more scratch resistant

This unique new addition to the Promaster Sea collection was inspired by the majestic orca, with contrasting bezel indentations that evoke its distinct markings and a stainless-steel bracelet that fastens with a fold-over clasp with push buttons.

This sleek Promaster Dive model features a deep-blue date-display dial and rotating bezel, and highly legible luminous hands and markers.

A three-hand date dial in the vibrant orange of an ocean sunset is surrounded by a blue rotating bezel with an aluminum ring that’s grooved for easy operation.

Given its sustainable light-powered Eco-Drive movement and its unmistakable DNA as a deep-water denizen, it’s no surprise this new Promaster Dive has been dubbed “Ecozilla.”

Inspired by a 1977 Citizen Challenger Diver
