Japanese watchmaker Citizen crafts timepieces built for every condition. With unmatched expertise, the brand produces highly equipped models drawing inspiration from different eras - all with impeccable quality. It now invites you to discover the Promaster Marine BJ8055-04X, an elegant yet distinctive men's watch. Designed for men, it features a round case measuring 48.20 mm in diameter and 18.50 mm in thickness. Crafted in brushed stainless steel with a brushed finish, it weighs 194 g and offers lasting durability. Antimagnetic, it is fitted with a mineral crystal protecting the dial, surrounded by a unidirectional bezel with a minute scale and a luminescent marker at 12 o'clock. At 9 o'clock - opposite the conventional position - a black, protected crown handles all central adjustments. Screw-down and knurled, it ensures a confident grip. The watch features a screw-down, engraved caseback for water resistance to 30 ATM.
This eye-catching dial makes a bold statement on this timepiece. It boasts a beautiful light green background against which the various markers are set for precise readability. Three black central hands sweep across it effortlessly - a slender seconds hand, a long minute hand, and a short hour hand. Together, they track the surrounding geometric hour markers and the minute track along the outer edge. To ensure optimal legibility in any conditions, both the hands and hour markers feature a luminescent coating. A date window at 3 o'clock adds a practical complication, while near 6 o'clock, the country of origin and water resistance rating are noted. The brand places its name and movement type just below 12 o'clock as its signature.
This watch is powered by an in-house Eco-Drive movement. Reliable and robust, this mechanism features a solar charging system. It delivers accuracy of +/- 15 sec per month and provides approximately 6 months of autonomy via its light-powered cell. It is specifically the B873-00M caliber developed by Citizen in its workshops in Japan, driving the hands and date display with precision.
Sleek and refined, this strap brings a striking accent to your wrist. In black, it pairs effortlessly with any accessory. Slightly ridged on the front, it is crafted from urethane - a lightweight, durable, and eco-friendly rubber. Subtle perforations add a touch of character, and it wears comfortably in any situation, even during high-intensity activities. The strap features a 32 mm lug width and secures with a black pin buckle for easy adjustment.
With water resistance to 30 atmospheres - equivalent to 300 meters - all our watch specialists have left to say is: enjoy your aquatic adventures. Fully waterproof, this model is ready for anything: shower, bath, swimming, freediving, or scuba diving - it handles it all. That said, to preserve the timepiece's lasting water resistance, our watchmakers recommend avoiding use of the pusher or crown while submerged.
