Movement of a hand seems strange
Before starting troubleshooting
Check movement of the second hand.
- Push the crown in to position 0.
- Check movement of the second hand.
!
When the second hand is moving once every two seconds, power reserve is nearly empty.
Charge immediately.
Charge the watch previously if required.
Summer time and the standard time do not switch automatically.
Possible cause and condition
| 1. | The watch has not received time signals successfully. |
| 2. | The setting for switching summer time and the standard time automatically is not activated. |
Check the causes and conditions above one by one to resolve the problem.
!
When you want to retry the checking from the first point during checking, reload this page and start again.
1. Checking the time zone setting
For automatic switching between summer time and the standard time, the watch must receive time signals in a area where summer time is implemented.
Refer to the maps of summer-time-implemented areas below to see the locations of the signal stations and their approximate receivable areas.
Receivable area: within a 1500-km radius from the station
Receivable area: within a 1000-km radius from the station
- Pull the crown out to position 1.
- Check the current time zone setting.
- Rotate the crown to select a time zone where signal reception is available.
- Push the crown in to position 0 to finish the procedure.
The second hand indicates the current time zone setting.
| Signal to receive | Time zone to set | Second hand position |
|---|---|---|
| USA (WWVB) | -8 | 40 |
| -7 | 43 | |
| -6 | 45 | |
| Germany (DCF77) | 0 | 0 |
| +1 | 3 |
Time indication is changed as you select a different time zone from the current one.
The watch returns to normal indication.
2. Receiving time signals manually
When receiving time signals, check the direction of the target signal station, remove the watch and place it on a stable surface where it can receive the signal better, such as next to a window.
- When wire glass is used for the window, open it or change the reception place.
- The reception antenna is located at the 8:00 position of the watch.
Place the watch with the 8:00 position facing toward the station. - Do not move the watch during time signal reception.
- Push the crown in to position 0.
- Press and hold the button for 2 seconds or more.
- Put the watch in the place with good conditions for time signal reception.
The second hand indicates the result of the last signal reception.
After that, the second hand points to “RX” and signal reception starts.
!
Do not move the watch as far as possible while the second hand points “RX”.
The watch returns to normal indication after the reception finished.
Did the watch receive time signals?
In environments where the watch cannot receive time signals, you must switch the summer time setting manually at every start and end of summer time.
Switching the summer time setting manually
- Pull the crown out to position 2.
- As summer time comes, rotate the crown clockwise to switch the summer time setting to “SMT ON”;
As summer time goes, rotate the crown counterclockwise to switch the summer time setting to “SMT OFF”. - Push the crown in to position 0 to finish the procedure.
The second hand indicates the current summer time setting.
| Indication of the second hand | Time currently indicated |
|---|---|
SMT ON  |
Summer time |
SMT OFF  |
Standard time |
The watch returns to normal indication.
3. Checking the summer time setting
- Pull the crown out to position 2.
- When it points “SMT OFF”, rotate the crown to clockwise to switch to “SMT ON”.
- Push the crown in to position 0 to finish the procedure.
The second hand indicates the current summer time setting.
| Indication of the second hand | Time currently indicated |
|---|---|
| SMT ON |
Summer time |
| SMT OFF |
Standard time |
When the second hand points “SMT ON”, push the crown in to position 0 to finish the procedure.
Summer time and the standard time will be switched automatically.
!
Doing this operation during non-summer-time period makes time indication summer time temporarily, but it returns to that of the standard time after receiving the standard time signal.
The watch returns to normal indication.
