Promaster Marine Eco-Drive BN0261-51E Watch

The Watch

The Citizen Promaster Marine men's watch stands out for its rugged, sophisticated look, designed for underwater adventure enthusiasts. Built in stainless steel, the 40 mm round case features brushed and polished finishes for a look that's both dynamic and refined. Its unidirectional bezel incorporates a visual countdown, an essential tool for experienced divers who need to track their dive time with precision. The screw-down crown ensures a perfect seal, resisting pressure up to 20 ATM. This solid construction is completed by a screw-down case back, adding an extra layer of protection for the internal movement.

The Dial

The black dial on this watch is a masterclass in legibility. Its matte sandblasted finish minimizes unwanted reflections underwater. The luminous hour markers and hands stand out clearly, essential for visibility in dark aquatic environments. Arabic numerals combined with a minute track make time reading precise and effortless. At 3 o'clock, a date window adds a practical complication with style. Protected by a flat anti-reflective sapphire crystal, the dial stays readable even in the harshest light conditions.

The Movement

Under the hood beats an advanced Eco-Drive caliber E168, a solar movement by Citizen that sets itself apart with its innovative technology. This caliber runs on quartz, delivering remarkable precision. The eco-friendly advantage of a solar movement is that it eliminates the need for battery replacement, ensuring sustainable, long-term reliability. With a 6-month power reserve, the timepiece stays active even in low-light conditions, guaranteeing consistent performance.

The Strap

Complementing the robustness of the case, the stainless steel bracelet delivers unmatched elegance. Its gray tone and brushed and polished finishes give the ensemble a modern, refined look. The bracelet is also designed for comfort, with a well-proportioned lug width that hugs the wrist securely. It fastens with a silver-tone deployment clasp, providing optimal security during even the most dynamic movements.

Water Resistance

The Citizen Promaster Marine's water resistance is engineered for the most extreme environments. With a water resistance rating of up to 20 atmospheres - the equivalent of 200 meters - this watch is ideal for professional scuba diving. It offers near-complete protection against water ingress, thanks in particular to its screw-down case back and screw-down crown, a dual-protection system that keeps the internal movement in perfect condition.
