The second hand will stop after 30-60 seconds of darkness or light insufficient for charging (such as under a shirt sleeve). Once the watch is exposed to light sufficient for charging, the second hand will “catch up” to the correct seconds and resume normal operation. After 48-60 hours of darkness or light insufficient for charging, the hour, minute, second and any special function hands will stop. Once the watch is exposed to light sufficient for charging, all hands will “catch up” to the correct time and resume normal operation.
