Replacement parts

Inspection and adjustment by disassembly and
cleaning (overhaul)
○ 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 may occur due to contamination of oil,
which may ultimately lead the watch to 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 "GRAND 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.
