● 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 due to contamination
of oil may advance or delay the time significantly, or the watch itself
may 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.
When your watch is inspected and adjusted by disassembly and cleaning
(overhauled), the movement of your watch may be replaced.

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".

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 the retailer from whom the watch
was purchased for repair.
・ Installation of an ordinary silver oxide battery can generate heat that can
cause bursting or ignition.
