Why is the small seconds hand on my Seiko Watch moving every 2 seconds?

  The small seconds hand moving every 2 seconds indicates that the energy depletion forewarning function is activated. This often happens when the watch isn't getting enough light, like when it's covered by a sleeve. To resolve this, ensure the watch receives sufficient light by keeping it exposed and charging it until the small seconds hand moves every second. When you take the watch off, place it in a bright location.

What to do if my Seiko 8B92 receives a signal but doesn't display the correct time?

  Joseph BarrettSep 8, 2025
  If your Seiko Watch receives a radio signal but doesn't show the precise time, it might be due to external interference causing incorrect reception or misaligned hand positions. First, try placing the watch in a location where it can receive a radio signal more easily and conduct manual reception if necessary. The automatic hand position alignment function will operate, and these will be corrected. Automatic Hand Position Adjustment Function activates once a minute for the small seconds hand and at 12:00 both for the AM and PM for the minute and hour hands. If urgent, perform manual time adjustment. If the watch still gains or loses time, reset the system. If problems persist, consult the retailer.

Why did the stopped small seconds hand on my Seiko 8B92 Watch start operating at the 45-second position?
- P
  Paige BassSep 10, 2025
  The stopped small seconds hand pointing to the 45-second position indicates that the power save function has been activated due to insufficient light exposure over time. To fix this, charge the watch until the small seconds hand moves every second. After charging, if the time is still incorrect, receive a radio wave as needed.

  If the crown or button on your Seiko Watch isn't working, it's likely because the stored electric power is low. Charge the watch until the small seconds hand moves every second.

What to do if my Seiko 8B92 doesn't resume normal movement after charging?

  Mark GravesSep 13, 2025
  If your Seiko Watch doesn't resume its normal one-second interval movements even after being exposed to light for the full charging time, it could be due to weak light exposure or an unstable built-in IC. Ensure the watch receives adequate light. The time required for charging the watch depends entirely on the amount of exposed light the watch receives. If the issue persists, reset the system.
