Citizen Eco-Drive wristwatch, steel, blue dial, BM7631-52L
Stainless Steel Citizen Eco-Drive Watch with Blue Dial, Angular Bezel and Date Display
A blue dial with a honeycomb pattern is surrounded by an angular steel bezel with a minute scale. The Citizen Eco-Drive BM7631-52L is a men's watch with a case and bracelet made of stainless steel. The case is 41 mm wide and 9 mm thick, and a mineral crystal protects the dial. The date display is at three o'clock, and luminous hands and indexes make the watch easier to read in low light.
The solar-powered Eco-Drive movement (caliber E111) is charged by light, so the battery never needs to be replaced. When fully charged, the power reserve is about 6 months, and an indicator on the dial shows the charge level. Eco-Drive is based on the Crystron Solar Cell, released in 1976, and the technology turns 50 in 2026. Water resistance of 100 m / 10 atm is enough for swimming, water sports and snorkeling. The watch is not suitable for scuba diving.
