● Inspection and adjustment by disassembly and cleaning (overhaul)
・ P eriodic 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 the 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.
