Citizen Eco-Drive J810-S109507 — Black Ion-Plated Stainless Steel, Black Dial, Date
 
Solar-powered and battery-free — a clean black-on-black dress watch that runs on any light.
Citizen's Eco-Drive line is powered by light, any light, and never needs a battery. The J810 movement stores energy in a rechargeable cell for months of reserve on a full charge. This model pairs that technology with a black ion-plated stainless steel case and matching bracelet, a black dial with luminous stick markers, and a date window. Understated, durable, and low-maintenance by design.
 
Excellent condition. Running and keeping time. The Eco-Drive movement holding charge as it should. No marks noted on the case, crystal, or bracelet.
Watch only: no box, papers, or extra links included
Bracelet currently sized to fit approximately a 6.5-inch wrist (+/-)
