The watch has been left at a low temperature (below 0°C).
Turn the crown to wind the mainspring. Under a low-temperature condition (below 0°C), the watch may stop when the power reserve indicator shows less than one-fourth of the power reserve.
The watch goes to the checkup mode when the crown is pulled out twice within 3 seconds. (The checkup mode is for delivery inspection.)
In order to return to the normal mode, push the crown back to its normal position, and pull it out to the second click, and then push it back again to its normal position. Even if the watch is left untouched while it is in the checkup mode, it will automatically return to the normal mode after a few minutes.
Wait until the watch starts moving normally to set the time.
The watch temporarily loses/gains time.
The watch has been left in extremely high or low temperatures for a long time.

operating.
To set the time correctly, wait for approximately 30 seconds
after the seconds hand starts to move, and set the time.
