The time shown would likely be incorrect and need to be reset after recharging the watch sufficiently. Why does my watch appear to have lost time, even though it is still running?Ī second important feature, Time Reset Advisory, warns that the citizen watch has stopped completely and then been exposed to enough light to start running again. For simple citizen analog models, pull the crown out to the time setting position for 30 seconds, and then return the crown to the closed position next to the case, then set the time. If you have fully charged your watch and the second hand continues to move in two second intervals, you need to do an all reset of the watch. This may also occur after fully recharging your watch after a complete discharge of the energy cell. It means that the reserve power is getting low and the energy cell needs to be fully recharged by exposing it to light for a period of time. The second hand on my watch jumps two seconds at a time

When this signal is seen, the watch should be exposed to bright light following the recharging guidelines shown in its instruction manual. A very important feature of Citizen Eco-Drive is the Low Charge Warning Mode which as a result of low energy cell voltage causes the second hand to jump two seconds at a time (while still keeping correct time). In normal use, the watch displays the time and the second hand moves in one second intervals. The Citizen Eco-Drive Energy Cell will last a lifetime of use.

The electrical energy is then stored in a special energy storage cell. The Citizen Eco-Drive watch uses a microns thin disc of amorphous Silicon under the dial to convert light energy into electrical energy through the photovoltaic process.

Eco-Drive ability to convert light energy to electrical energy means that its power is limitless.

A combination of solar conversion panel and energy cell is the power provider for these watches. Citizen Eco-Drive Watches: How to use and maintain?Ĭitizen Eco-Drive watches use the simplest, yet most advanced power generating and storage system.
