Grand Seiko Watch Repair & Service

Grand Seiko makes watches with three kinds of movement: mechanical, Spring Drive and quartz. It backs new watches with a 5-year worldwide warranty and sets no fixed limit on how long it will repair one.

Grand Seiko factory service

Grand Seiko's manuals recommend an overhaul, meaning disassembly, cleaning and adjustment, approximately every 3 to 4 years. Its Complete Service pairs that overhaul with a light polish of the case and metal bracelet.

• Warranty: 5 years worldwide from purchase, issued by an authorized Grand Seiko dealer.
• Requesting service: online, through the original retailer, or through Grand Seiko's international service network.
• Parts: the service network holds extensive inventories, often for many years after a model ends.

Independent Grand Seiko service

Use Grand Seiko while the warranty runs. After that, match the watchmaker to the movement: mechanical, Spring Drive and quartz each need different experience. Grand Seiko's manuals also call for genuine Grand Seiko parts and new gaskets at each overhaul.

Before you ship, ask

• Is my watch still under Grand Seiko's 5-year warranty? If so, use Grand Seiko first.
• Have you serviced this movement type (mechanical, Spring Drive or quartz) before?
• Do you use genuine Grand Seiko parts, and will you replace the gaskets?
• Will you polish the case? If you would rather keep the original finish, say so in writing.
• Are you authorized by Grand Seiko for service, and where does that show on Grand Seiko's own website?
• Will the work be done on site, or sent elsewhere? If it is sent on, where does it go, and does the quote add a fee on top of the service center's charge?

Providers on this page were researched against our Standard at the time they were listed and are rechecked periodically. Details can change between checks, so confirm terms, pricing and turnaround directly with the provider before sending your watch.
