Celebrating 50 years of Citizen’s pioneering Eco-Drive technology, the Citizen Eco-Drive Promaster Marine BN0264-53E Diver’s Limited Edition combines striking design with professional dive-watch performance. Limited to just 6,700 pieces worldwide, this special edition features a bold black stainless steel case and bracelet with gold-tone accents, a textured black dial with luminous baton and dot markers, and a practical date window for everyday convenience. Part of the LIGHT in BLACK collection, the design symbolises a single beam of light illuminating darkness, with gold-coloured details representing the power source behind Eco-Drive technology. The dial showcases five overlapping patterns created using advanced inkjet printing techniques, adding depth and commemorating Eco-Drive’s 50th anniversary. Powered by Citizen’s Eco-Drive Calibre E168 movement, the watch runs on any light source, eliminating the need for battery replacements. The 40.6mm stainless steel case with black ion plating is protected by a scratch-resistant sapphire crystal and features a screw-back case, screw-down crown, and one-way elapsed-time rotating bezel for enhanced durability and functionality. Luminous hands and markers ensure excellent legibility, making this limited-edition Promaster an ideal companion for both underwater adventures and everyday wear. 6,700pcs Worldwide - Eco-Drive Movement - Caliber E168 - 40.6mm Case Size - Stainless Steel + Iron Plating Case and Bracelet - Sapphire Crystal - Date Window - Screw-back case - Screw-down case - One-way elapsed time rotating bezel - Luminous hands
