Recommandations for charge
When charging the watch, do not place it too close to a photo light bulb,
spotlight, incandescent lamp or other light source as the temperature of the
watch may become extremely high, which would damage the built-in parts.
If you expose the watch to sunlight to recharge it, do not place it for a long time
on the dashboard of a car, etc. because the temperature of the watch could rise
very strongly.
When charging the watch, make sure the temperature does not exceed 60 ° C. It
is not necessary to fully charge the watch, but it should be recharged enough,
especially during the initial recharge.
Other remark on the power source
Never insert a conventional silver oxide battery into this watch as it may explode,
heat or catch fire. The watch is designed so that it does not work if a
conventional battery is installed.
