Citizen PROMASTER MARINE BN0261-51E Diver Watch Eco-Drive
Product Description
The Citizen PROMASTER MARINE BN0261-51E watch is a professional diver watch from the Citizen Promaster Marine Series, combining reliable underwater performance with a classic and minimalist diver design.
This model features a compact 40.6 mm stainless steel case, providing excellent comfort while maintaining the robust presence expected from a professional diver watch. The unidirectional rotating bezel is designed with deep grooves around the edge, ensuring a firm grip and smooth operation even in wet environments or when wearing diving gloves.
The dial adopts a clean, plain black design without gradients or patterns, creating a stylish and highly legible appearance. The strong contrast between the clear black dial and bright white markers enhances readability, giving the watch a crisp and modern look suitable for both diving and everyday wear.
Powered by Citizen’s Eco-Drive solar technology, the watch converts sunlight or indoor light into energy. Once fully charged, it can run for approximately 6 months, eliminating the need for regular battery replacement.
With 200m diver water resistance, a screw-lock crown, luminous hands and indexes, and a sapphire crystal with anti-reflective coating, the watch is built to withstand demanding underwater conditions. The three-link stainless steel bracelet features a strong dimensional design with mirror-finished center links, while the ratchet-equipped double holding clasp allows easy adjustment when wearing a diving suit.
This model delivers a perfect combination of durability, simplicity, and professional diving functionality.
