When the second hand jumps in 2-second intervals or stops
A solar watch does not need a periodical battery replacement, but it has stopped.
Does it need a repair?
There is a possibility of a rechargeable battery being out of charge. Please try recharging it by exposing it to sunlight.
Jumps in 2-second intervals
It is a sign that the energy stored in the rechargeable battery is reduced to an extremely low level.
When this occurs, some of the watch functions and calendar function may stop working for certain calibers.
In that case, please recharge the watch before it stops completely.
Stopped at the 15-second position
If your watch features a power save function, the watch will enter "Power Save 1" mode after 72 hours without receiving a sufficient light source. In this mode, the second hand stops at the 15-second position, and the hour and minute hands also stop.
When the watch is exposed to a sufficient light source for five seconds or longer, it will display the current time again after the second hand is rapidly advanced.
Stopped at the 45-second position
If your watch features a power save function, the watch will enter "Power Save 2" mode when the watch is in an insufficient charging state for a long time.
The second hand stops at the 45-second position, and the hour and minute hands also stop.
After sufficiently recharging the watch, set it for the current time if necessary.
When the hands are stopped completely, there is a possibility of the rechargeable battery being out of charge. If this occurs, please recharge it by a window by exposing it to sunlight for 5-6 hours before using it again. In case the watch is used before a sufficient recharging, it may stop again.
When recharging the watch, make sure that the watch is not heated to a high temperature.
Completely stopped after recharging
In case the watch does not move even after it is exposed to sunlight for 5-6 hours, it might need a repair.
