Module No. 5698
Charging
This watch runs on power supplied from a rechargeable (secondary) battery that is charged by a solar panel. The solar panel is integrated into the face of the watch, and power is generated whenever the face is exposed to light.
Charging the Watch
When you are not wearing the watch, put it in a location where it is exposed to bright light.
While you are wearing the watch, make sure that its face (solar panel) is not blocked from light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially.
Important!
Some light sources and environments can cause the watch to become extremely hot during charging, which creates the risk of burn injury and damage to internal watch components.
Avoid charging the watch under conditions like the ones described below, where the temperatures may exceed 60 °C (140 °F).
On the dashboard of a vehicle parked in the sun
Near incandescent lamps, camera lights, halogen lamps, or other sources of heat
In locations exposed to direct sunlight for long periods and other hot locations
Checking the Charge Level
In the Timekeeping Mode, the function hand indicates the current charge level.

Low Battery
Low Battery
A low battery will cause [LOW] to flash and will disable the functions below.
Illumination
Sounds (alarm, etc.)
Connection with a phone
If the charge level drops even further, [CHG] will flash and the hour and minute hands will stop at 12 o’clock. If this happens, all functions are disabled.
Dead Battery
The digital display will go blank if the battery goes dead. Memory data is lost, and watch settings are returned to their initial factory defaults.
Important!
Should the battery go low or go dead, expose the face (solar panel) to light as soon as possible.
Exposing the watch to light while its battery is dead will cause [CHG] to start flashing. Expose the watch to light to charge it until the Timekeeping Mode screen re-appears.
Note
If [R] is flashing, it means that all functions, except for timekeeping, are disabled due to high momentary battery power consumption.
