Citizen Eco-Drive Classic watch, steel, black dial, AW0100-86E
Stainless Steel Citizen Eco-Drive Classic Watch with Black Dial and Day and Date Windows
The black dial has two windows: the day of the week at twelve o'clock and the date at six o'clock. The center of the dial has a radial pattern, and the silver-coloured hour markers stand out clearly against the black. The round stainless steel case is 40 mm wide and 10 mm thick. The bracelet, made of the same material, is 21 mm wide. The hands are not luminous.
The Eco-Drive movement is charged by light, so the battery never needs replacing. When fully charged, the watch runs for up to 240 days. In 2026, Citizen's Eco-Drive turns 50 years old. Water resistance of 30 m / 3 atm is enough for sweat, splashes, rain and hand washing, but not for swimming.
