Charging your watch
When the watch reaches a low charge state (insufficient charge warning
function)
When the power reserve becomes low, the second hand
moves once every two seconds. This is the insufficient
charge warning function. Be sure to fully charge your
watch immediately as outlined on page 24.
• When the watch is sufficiently charged, the second
hand will move normally.
• If you do not charge the watch for 2 days or longer after
the insufficient charge warning movement has begun, the watch will be depleted
of all power and stop.
