Solar-powered chronograph for daily wear

The Citizen Promaster JY8085-81E combines a solar Eco-Drive movement with a 200 m water-resistant stainless-steel case. An analog-digital dial shows the day and date alongside index markers with numerals at 3, 6 and 9 o'clock. A sapphire crystal protects the black face from scratches during regular activity.

Thermals noise and power in normal use

Solar charging removes the need for battery changes and produces no audible noise or measurable heat on the wrist. The Caliber U680 movement runs from ambient light so power draw is effectively zero during everyday wear. Stainless-steel construction maintains a neutral temperature against the skin in typical conditions.

Behaviour under sustained load

Continuous exposure to water at depth up to 200 m is supported by the screw-down case and deployment clasp. The analog-digital module and chronograph functions operate without interruption during extended timing sessions. Sapphire crystal retains clarity after repeated impacts common in sports or field use. Buyers who need a dive computer with integrated gas-mix algorithms should look elsewhere.

Questions about this item

How do I set the time on the U680 Eco-Drive movement and which step is often missed?

Expose the dial to bright light until the power reserve is full, then pull the crown to the time-setting position; the step many miss is waiting for the radio signal to sync automatically overnight.

What part of the U680 solar movement will need replacement after several years?

The internal rechargeable cell that stores energy from the Eco-Drive system eventually loses capacity and must be swapped by a watchmaker.

Which limit appears first during continuous deep diving with the 200 m water resistance rating?

The 200 m depth rating itself is the limiting factor; exceeding it risks case or crystal failure before any other component reaches its limit.
