Power source

The battery used in this watch is a special secondary battery, which is totally diﬀerent from ordinary silver oxide batteries.

Unlike other disposable batteries such as dry-cell batteries or button cells, this secondary battery can be used over and

over again by repeating the cycles of discharging and recharging.

However, for various reasons such as long-term use or usage conditions, the capacity or recharging efficiency of the

secondary battery may gradually deteriorate. Worn or contaminated mechanical parts or degraded oils may also shorten

recharging cycles. If the eﬃciency of the secondary battery decreases, have the watch repaired.

■ Remarks on replacing the secondary battery

・ Do not remove the secondary battery yourself.

Replacement of the secondary battery requires professional

knowledge and skill. Please ask a watch retailer for repair.

・ Installation of an ordinary silver oxide battery can generate heat that

can cause bursting or ignition.

WARNING

※ Refer to "Guideline of charging time" on page 54 to check the time required for fully charging the watch.

When the secondary battery is fully charged, the overcharge prevention function

is automatically activated to avoid further charging. There is no need to worry

about damage caused by overcharging no matter how much the secondary

battery is charged in excess of the "time required for fully charging the watch".

※ Overcharge prevention function

■ Notes on charging the watch

・ When recharging the watch,do not place it too close to incandescent

light or other light sources as the watch temperature will become

extremely high, causing damage to the parts inside the watch.

Inspection and adjustment by disassembly and cleaning (overhaul)

・ Periodic inspection and adjustment by disassembly and cleaning (overhaul)

is recommended approximately once every 3 to 4 years in order to maintain

optimal performance of the watch for a long time. According to use

conditions, the oil retaining condition of your watch mechanical parts may

deteriorate, abrasion of the parts may occur due to contamination of oil,

which may ultimately lead the watch itself to stop. As the parts such as

gasket may deteriorate, water-resistant performance may be impaired due to

intrusion of perspiration and moisture. Please contact the retailer from whom

the watch was purchased for inspection and adjustment by disassembly

and cleaning (overhaul). For replacement of parts, please specify "SEIKO

GENUINE PARTS." When asking for inspection and adjustment by

disassembly and cleaning (overhaul), make sure that the gasket and push pin

are also replaced with new ones.
