Manual: Citizen Eco Drive Gn-4w-s-12g

So, you’ve got a Citizen Eco-Drive with the "GN-4W-S" marking on the back. It’s a classic, reliable piece of engineering, but if you’ve lost the manual, you might be wondering why the second hand is jumping or how to actually change the date without breaking it.

• How it works: It converts light (natural or artificial) into electrical energy to power the watch.

  Charging & Power Reserve

  • Eco-Drive converts light (sunlight and artificial) to energy stored in a rechargeable cell.
  • Approximate full-charge power reserve: commonly 6 months in normal operation for many Eco-Drive movements; some claim up to 8–12 months for certain variants — consult specific model docs to confirm.
  • Power save / insufficient-charge warning: If the second hand starts moving in 2-second intervals (or stops), this indicates low charge — expose watch to light.
  • Typical recharging durations (approximate; varies by light intensity and model):
    • If the chronograph hands do not return to zero: Pull the crown out to Position 2 and press the buttons to realign the hands to the 12 o'clock position.
