Charging the Watch
The face of the watch is a solar panel that generates power from light. The generated
power charges a built-in rechargeable battery, which powers watch operations. The
watch charges whenever it is exposed to light.
Charging Guide
Whenever you are not
wearing the watch, be sure
to leave it in a location
where it is exposed to light.
Best charging
performance is achieved
by exposing the watch to
light that is as strong as
possible.

Warning!
Leaving the watch in bright light for charging can cause it to become quite hot.
Take care when handling the watch to avoid burn injury. The watch can become
particularly hot when exposed to the following conditions for long periods.
On the dashboard of a car parked in direct sunlight
Too close to an incandescent lamp
Under direct sunlight
Important!
Keep the watch in an area normally exposed to bright light when storing it for long
periods. This helps to ensure that power does not run down.
Storing the watch for long periods in an area where there is no light or wearing it in
such a way that it is blocked from exposure to light can cause power to run down.
Make sure that the watch is exposed to bright light whenever possible.
When power drops to Level 4, all functions will be disabled but the watch will
continue to keep time internally for about one week. If you recharge the battery
suffi ciently during this period, the analog hands will move automatically to the
correct setting and regular timekeeping will resume. After one week, all settings
(including timekeeping) will be cleared. Recharging the battery will reset all settings
to their initial factory defaults.
Charging Guide
The charging guide causes the x Second Hand to perform movement that gives you
a rough idea of whether the watch needs to be exposed to light in order to charge the
battery.
The current charging requirement is indicated whenever you push the crown
back in from the fi rst click.
Failure to expose the watch to light when charging is required will cause the
charge to be reduced even further.
The charging guide is based on a calculated value (not the actual battery
charge). Because of this, the battery charge may go low even if the charging
guide indicates that immediate charging is not required. If this happens, expose
the watch to light as soon as possible to charge the battery.
