Charging the battery
■ How to charge the battery
Expose the dial to light to charge the watch.
To ensure optimal performance of the watch, make
sure that the watch is kept sufficiently charged at all
times.
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.
* Be careful to make sure that the watch does not get hot when it is charging. (The operating temperature range is
-10°C to +60°C.)
* When you first start using the watch or starting it after it stopped due to a lack of charge, charge the watch sufficiently
using the table on P.18 as a guide.
* Two-second interval movement by the seconds hand is a signal that the energy of the watch is nearly depleted.

■ Guide to charging times
Charge the watch using the times below as a guide.
The “Time required for charging the watch to stable hand movement” figure is an estimate of the amount
of time required to expose the stopped watch to light and charge the watch until it reaches stable hand
movement (for models with a seconds hand: until it reaches one-second interval movement). Charge the
watch using these times as a guide.
* The required charging time slightly varies depending on the model of the watch.
