My watch keeps losing time!

Your Citizen Eco-Drive watch may be losing time because the capacitor is no longer able to hold a charge. This can happen over time, especially if the watch is not regularly exposed to light. If the watch is not keeping accurate time or stops working, it may need a new capacitor or even a movement replacement.

Page 25: Eco-Drive (Solar Powered) Watch Handling Precautions
Eco-Drive (solar powered) watch handling precautions <Always Make Sure to Recharge Frequently> • For optimal performance, your watch should remain fully charged. • Long sleeves may inhibit light transmission to your watch. This may result in your watch loosing charge. In these cases supplemental charging may be necessary. • When you take off the watch, place it in a bright location to ensure optimal performance.
Page 26 Eco-Drive (solar-powered) watch handling precautions CAUTION Recharging Precautions • Do not charge the watch at a high temperature (about 60°C (140°F) or higher) as doing so may cause the movement to malfunction. Examples: • Charging the watch too close to a light source which generates a large amount of heat such as an incandescent lamp or halogen lamp. * When charging under an incandescent lamp, be sure to leave 50 cm (20 inches) or more between the lamp and the watch to avoid exposing the watch to excessive heat.
Page 27 Eco-Drive (solar-powered) watch handling precautions <Replacement of Rechargeable Cell> • This watch utilizes a special rechargeable cell that does not require periodical replacement. However power consumption may increase after using the watch for a number of years due to wear of internal components and deterioration of oils. This may cause stored power to be depleted at a faster rate.
Page 28 Eco-Drive (solar-powered) watch handling precautions WARNING Use Only the Specified Battery • Never use a battery other than the rechargeable cell specified for use in this watch. Although the watch structure is designed so that it will not operate when another type of battery is installed, if a conventional watch battery or other type of battery is installed in the watch and the watch is recharged, there is the risk of overcharging which may cause the battery to rupture.
Page 29: Water Resistance
Water resistance WARNING Water Resistance • Refer to the watch dial and/or the case back for the indication of the water resistance of your watch. The following chart provides examples of use for reference to ensure that your watch is used properly. (The unit “1 bar” is roughly equal to 1 atmosphere.) • WATER RESIST(ANT) ×× bar may also be indicated as W. R. ×× bar. Indication Name Specification Dial or Case back Non-water resistant —...
