How to Recharge an Eco-Drive Watch

The Citizen Eco-Drive watch never needs a battery. This luxury timepiece relies on light to power its digital and analogue displays. It can convert all forms of light into energy and rarely needs to be recharged. If you've left your watch in the dark, you may notice that it's losing time or has stopped completely, or that the second hand ticks in two-second increments. Any one of these means it's time to recharge your Eco-Drive.

  1. 1

    Recharge your watch using sunlight if it's stopped completely. Recharge times vary according to model but it will take an average of 9 to 12 hours on a cloudy day and 3 to 5 hours on a sunny day.

  2. 2

    Place the watch in a secure place in direct sunlight. Avoid exposure to water. Check the watch intermittently. You'll know it's recharged when it starts to tick.

  3. 3

    Recharge your watch under an incandescent light if it's raining or you don't have access to a secure spot in direct sunlight. This process will take a lot longer. You'll have to place the watch directly under a light source that's at least 20 inches away. Recharging this way may take more than 40 hours.

Tips and warnings

  • You'll need to reset your watch after it's been recharged. Consult your user's manual for instructions on how to do so. There's an online option for instructions on resetting available in the "Resources" section.
  • Different Citizen Eco-Drive watches have different recharge times. Consult the Citizen Web page in the "Resources" section to find the time for yours.
  • Direct sunlight is the best way to recharge your watch but office light is sufficient to keep it going.
  • Never use a halogen or flood-type of lamp; the heat generated may damage your watch.
