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.
