he Citizen Promaster Blue Dial is more than a watch: it is a precision instrument designed for diving and water sports enthusiasts. With Diver's certification, this timepiece combines the robustness of steel with the legendary reliability of Citizen technology.

Eco-Drive Technology: Solar Energy at Your Service
Forget the thought of the battery running out at the least opportune moment. At the heart of the Promaster is the Eco-Drive system, which turns any source of light (solar or artificial) into energy. This ensures infinite autonomy and constant accuracy while reducing environmental impact.

Rugged Construction for Underwater Exploration
Designed to withstand extreme conditions, the watch features a 44mm stainless steel case with satin finish. Safety is ensured by the screw-locked crown and case back, which allow guaranteed water resistance to 200 meters (20 ATM). The unidirectional rotating bezel allows dive times to be monitored with the utmost precision and safety.

Superior Readability and Comfort
Beneath the high-strength mineral crystal, the deep blue dial houses baton hour markers, Arabic numerals and oversized arrow hands. Thanks to the luminescent treatment, reading the time is immediate even in marine darkness. The black polyurethane rubber strap was chosen for its resistance to salt corrosion and to offer an ergonomic, lightweight fit on any wrist.
