Charging Instruction for Seiko and Citizen Solar Watches

Guide to Charging and Recharging Eco-Drive Watches

Citizen Eco-Drive watches use an environmentally friendly highly specialized rechargeable cell to store electrical energy. When the watch is fully charged, most

Eco-Drive watches have a power reserve of 6 months or more. Some specialized models may feature a shorter power reserve, while others may have up to a 5 year power reserve.

To ensure optimal operation of your watch, expose your watch to direct sunlight at least once (1) each month, for at least five (5) hours.

An effective way of charging your watch is to keep it in a bright location when you are not wearing it, such as near a window where it can receive direct sunlight. Be sure to avoid charging your watch on a surface that can become extremely hot, such as a car dashboard as this can damage sensitive components within your watch. 

The dial (face) of the watch should face towards the window so that it can “see” the sun (see photo). We suggest positioning the watch on it’s three or nine o’clock edge so that the dial (face) of the watch is pointing towards  the window, rather than at the ceiling.  This will ensure the most light possible can reach the dial (face) watch.                                                         

This photo shows a less than optimal position for charging, as the watch lying flat on the window sill, facing the ceiling. This minimizes the amount of light that can reach the watch. If the watch does not face the window/sun directly, light that reaches the watch dial (face) of the watch will be minimized.

Charge times will vary by the movement featured in your watch. You can find recharge information on the Citizen website at:

NOTE--->>> According to the Instruction Sheet - it is 

EXTREMELY IMPORTANT that the watch face "OUTWARD" thru the window TOWARDS the OUTSIDE and NOT lay flat facing "UP" towards the ceiling of the room. 

The watch needs to "SEE" the SUN and not look at the ceiling.
