Your watch runs on electrical power generated from light and stored
by a chargeable battery. Long-term storage of the watch can cause
the battery to run low, so be sure to expose the watch to light for
some time before using it for the first time. See “Solar Charging” for
more information.

When secondary battery power is low, the second hand of the watch
will start to jump at 2-second intervals to let you know that charging
is required.
• See “Low Battery Alert” for more information.
