NOTE ON POWER SUPPLY
The battery used in this watch is a rechargeable battery, which is different from
ordinary silver oxide batteries. Unlike other disposable batteries such as dry-
cell batteries or button cells, this rechargeable battery can be used over and
over again by repeating the cycles of discharging and recharging.
The capacity or recharging efciency of the rechargeable battery may gradually
deteriorate for various reasons such as long-term use or usage conditions.
Worn or contaminated mechanical parts or degraded oils may also shorten
recharging cycles. If the efciency of the rechargeable battery decreases, it will
be necessary to have the watch repaired.
When the secondary battery is fully charged, the overcharge prevention
function is automatically activated to avoid further charging.
Do not remove the rechargeable battery yourself. Replacement of the
rechargeable battery requires professional knowledge and skill. Please
ask a watch retailer for replacement of the rechargeable battery.
Installation of an ordinary silver oxide battery can generate heat that can
cause bursting and ignition.
CAUTION
If the “Power Save 2” mode is prolonged, the stored power amount drops and the internal current time
information stored will be lost. When the watch returns to its normal movement of one-second interval
after the battery is sufciently charged, set the current time by receiving a radio signal.
