...How to charge the watch

Expose the dial to light to charge the watch.

Under the following situations, the energy of the watch is likely to

be depleted, resulting in stoppage of the watch.

・ The watch is concealed under a sleeve.

・ The watch is used or stored under conditions where it cannot be

exposed to light for a long time.

※... W hen... charging... the... watch,... make... sure... that... the... watch... is... not... heated... to... a... high...
