● 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.
