The Citizen Promaster Dive 36mm Watch is a solar-powered analog timepiece designed for aquatic adventures. It features a durable silver-tone stainless steel case and a black rotating bezel, complemented by a black dial with luminous silver-tone alpha hands and round markers for clear visibility. The watch is equipped with a screw-down crown and a black polyurethane strap, offering water resistance up to 200 meters (20 Bar), making it suitable for serious diving. This Promaster model includes a date indicator function and is protected by a mineral crystal, backed by a 5-year limited warranty for both parts and labor.
