Watch Overhaul & Movement Service in Tokyo

A standard overhaul includes disassembly, cleaning, lubrication, reassembly, adjustment, and accuracy testing. Parts are repaired or replaced when required.

A repair addresses a specific fault, while an overhaul services the movement as a whole through disassembly, cleaning, lubrication, reassembly, adjustment, and testing. We inspect the watch and recommend the work appropriate to its condition.

A common guideline is approximately every three to five years, but the appropriate interval varies by brand, movement, use, and manufacturer guidance. Please consult us if the watch loses accuracy, stops, or feels unusual when winding.

Possible signs include gaining or losing more time than usual, stopping unexpectedly, reduced power reserve, resistance or unusual noise when winding, and condensation inside the crystal. Stop using the watch and request an inspection if moisture is visible.

Reference prices start at ¥34,000 including tax for quartz watches and ¥44,000 including tax for mechanical watches. Vintage and antique watches require an individual estimate. Parts and additional work are charged separately.

Yes. We inspect the watch and provide a free estimate. Repair work begins only after you approve the price.

The estimate normally takes about two weeks. Service generally takes about three weeks to one and a half months, depending on the watch, condition, and parts availability.

No. An overhaul requires disassembly, cleaning, assembly, adjustment, and final testing, so the watch must be left with us. The estimate normally takes about two weeks, followed by the repair period after approval.

Yes, in some cases. If battery replacement does not restore operation or the movement has contamination, corrosion, or mechanical wear, movement service, repair, or replacement may be required.

We assess chronographs and other complicated watches individually. Their construction and number of components may increase the price and turnaround time, which we explain in the estimate.

Yes. Vintage and antique watches are assessed individually because movement condition, previous repairs, and parts availability vary. We explain the feasible repair and restoration options after inspection.

We assess a wide range of Japanese and international brands, including Rolex, Cartier, Omega, TAG Heuer, IWC, Seiko, Citizen, MINASE, Tutima Glashütte, RAYMOND WEIL, and many others. Vintage watches and special constructions are assessed individually.

Where available, genuine parts can be arranged. If a required part is difficult to source, we explain repair, restoration, custom-fabrication, or manufacturer-service options before proceeding.

We first confirm whether the existing part can be repaired or whether custom fabrication or manufacturer service is possible. We explain the available options and cost before carrying out additional work.

Water-resistance testing and gasket replacement are performed when required and may be quoted separately. The original water-resistance performance may not be restorable on some vintage watches or cases with deterioration.

Yes. Case and bracelet cleaning or refinishing can be discussed and quoted separately. We confirm your preference before work because polishing changes the existing surface and edges.
