This watch is a combination solar-powered watch that contains a solar cell in its
face that drives the watch hands, race timer, chronograph, alarm, and numerous
other functions by converting light energy into electrical energy.
It is also equipped with convenient functions including a power save mode that
reduces power consumption when light is not shining on the solar cell, UTC
(Coordinated Universal Time) and a world timer indicating the time and dates of
30 major cities around the world.

other toxic substances. Once fully charged, the watch will continue to run for a
maximum of 4 years without additional charging (when in the power save 2
mode).
[Proper use of this watch]
To use this watch comfortably, make sure to recharge it before it stops running
completely. There is no risk of overcharging the watch no matter how often it is
recharged. (Overcharging Prevention Function).
