Official Grand Seiko service or independent watchmaker?
Choose the official network if the watch is under factory warranty (unauthorized service voids it at most brands), if you plan to sell with full service documentation, or if the movement needs brand-specific tooling. Choose a reputable independent for out-of-warranty watches when cost and turnaround matter — see our full comparison in Official vs Independent Watchmaker.
