Citizen Eco-Drive Chronograph AT2565-05E 43mm Black Dial Silicone Strap 100M Solar Watch

Light-Powered Sports Chronograph

The Citizen Eco-Drive Chronograph AT2565-05E is a 43 mm stainless-steel watch with a black dial, mineral crystal and a black silicone strap. Its solar-powered movement runs on any light source and stores energy for up to 150 days without further exposure. The chronograph function measures up to 60 minutes in one-second increments and includes a 24-hour sub-dial plus a date window. Water resistance is rated at 100 metres, making it suitable for swimming and active daily wear.

Build Integration and Freedoms

The fixed stainless-steel bezel features a tachymeter scale for speed calculations, while the screw-down case back and pull/push crown maintain the 100 metre seal. A textured silicone band with a buckle clasp secures the watch without metal bracelet weight or pin adjustments. Because the Eco-Drive calibre H500 recharges from ambient light, the owner never needs to open the case for battery changes, freeing up time and eliminating a common maintenance task.

Sustained Load Behaviour

Under continuous wear the solar cell tops up the reserve daily, so the 150 day power buffer remains intact even through weeks of low light. The quartz regulator keeps steady accuracy during prolonged chronograph runs, and the mineral crystal resists scratches from repeated desk, gym or outdoor contact. Silicone retains flexibility and grip across temperature swings, preventing strap fatigue during all-day, multi-activity use.
