Servicing recommendations
Care and servicing
Maintenance can support longevity without guaranteeing it. Seiko explains that worn parts and aged oil can impair operation and recommends servicing about every three years. Follow the recommendation for the brand and calibre: three years is not a universal rule. Seiko also recommends regular water-resistance checks. Seiko — care and servicing.
For a full overhaul, Seiko describes cleaning and re-oiling disassembled parts. The exact work depends on the model and agreed service scope: do not assume that all seals are always replaced or every contact lubricated. Have the designated lubrication points and products for the calibre respected. Seiko — care and servicing.
A mechanical watch affected by magnetism can remain magnetized after removal from the source; Seiko recommends demagnetization. A rate change does not prove this cause or guarantee that demagnetization will suffice. Have changes in operation or a new, unusual noise inspected, without assuming that an audible rotor is necessarily faulty. Seiko — magnetism.
For a stored watch or one without obvious symptoms, request an assessment based on its condition and the manufacturer’s guidance rather than inferring an automatic need for overhaul solely from stoppage or time in storage. Seiko — care and servicing.

Frequently asked questions
How often should an automatic watch be serviced?
Seiko recommends servicing its watches about every three years; follow your manufacturer’s guidance.
Does a watch that suddenly runs fast mean it is magnetized?
Not necessarily: rate alone does not prove magnetism. Seiko says a magnetized mechanical watch remains so after removal from the source.
What does a complete service include?
Seiko describes disassembly, cleaning and re-oiling parts, as well as regular water-resistance checks.
