Inspection and adjustment by disassembly and cleaning (Overhaul)

• Periodic inspection and adjustment by disassembly and cleaning (overhaul) is recommended

approximately once every 2 to 3 years in order to maintain optimal performance of the watch for a long

time.

• The power transmission gear of the movement of this watch constantly receives force. To ensure that

this mechanism works properly all the time, washing parts, changing oil, adjusting accuracy, checking

functions and replacing consumable parts on a regular basis are important. The first overhaul after the

purchase of your watch is particularly important for preserving long-time use of your watch. 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.

Inspection and adjustment by disassembly and cleaning (overhaul) should be performed by the retailer

from whom the watch was purchased, and who specifies “SEIKO GENUINE PARTS.” At this time, also

request replacement of the gasket and the spring bar.

• When your watch is inspected and adjusted by disassembly and cleaning (overhauled), the movement

of your watch may be replaced.
