If your Citizen Watch has stopped, ensure it's adequately charged until the charge level indicator reaches level 3. If the issue persists, reset the watch and correct the reference position. If 'ERR' is still displayed, it indicates a need for professional assistance.
Why is the time not correct on my Citizen Watch?
If your Citizen Watch isn't displaying the correct time, try changing your location and attempt to receive the radio wave again. In TME or WT-S mode, verify that the daylight saving time setting is correctly selected to either ON or OFF.
How to fix radio signal reception on my Citizen Watch?
If your Citizen Watch is unable to receive radio signals, pull the crown out to position 1 and set the mode to TME, CAL, or RX-S. Stop any measurements in progress, reset the watch, and then try to receive the radio wave again. Also, ensure that the reference position is correctly set; if not, adjust it as described in “Adjusting the Reference Position.”
