watch can be reconditioned within this period if used normally.

on the conditions under which it was used, and normal accuracy may not be achieved
in some cases. We recommend, therefore, that you consult the retailer from whom the
watch was purchased when having them repair your watch.

・Notes on overhaul
To Preserve the Quality of Your Watch
・ 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. 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 fi rst
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 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.
