・ 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 signifi cantly, 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.
● Inspection and adjustment by disassembly and cleaning (overhaul)
Depending on the environment where a diver's watch is
used, its inner parts or movement as well as its case or

Power Source
The battery used in this watch is a special secondary battery, which is totally diff erent 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 effi ciency of the
secondary battery may gradually deteriorate. Worn or contaminated mechanical parts or degraded oils may also shorten
recharging cycles. If the effi ciency 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.
