Citizen Eco-Drive wristwatch, steel, green dial, BM7620-83X
Citizen Eco-Drive Steel Watch with Green Dial, Date Display and Luminous Hands
The green dial of this Citizen Eco-Drive watch gets its look from a radial brushed finish, and the faceted bezel gives the steel case sharp lines. The case is 38 mm wide and 10 mm thick, so the watch is moderate in size. The date display shows the date, and the luminous hands make it easier to read the time in the dark.
Light charges the Eco-Drive movement, so you never need to replace a battery. When fully charged, the watch runs for 180 days. Water resistance of 100 m / 10 atm is enough for swimming, water sports and snorkeling, but not for scuba diving. The steel bracelet is 20 mm wide and fits wrists of 155–210 mm. Eco-Drive's 50th anniversary year is 2026.
