Mechanical watch service or a specific repair?

Servicing a mechanical watch and repairing a particular fault are different assignments. A service may address the movement more broadly, while a repair targets an identified problem. The exact scope depends on the watchmaker’s assessment.

Describe how the watch behaves

Give the model, approximate age if known, and service history. Explain whether the watch stops, keeps time differently, or has an adjustment that no longer works as before. Mention any impact or other event preceding the change.

Do not attempt to repair the movement yourself or force a stuck adjustment. Ask how to deliver the watch for assessment and what the examination costs.

Ask about options based on the assessment

Request a description of the confirmed fault, proposed work, and replacement parts. Ask whether a limited repair makes sense or a fuller service is needed. Clarify which functions will be checked afterward and what remains outside the scope.

Separate work on the movement from changes to appearance. Polishing the case or altering other visible parts can be a significant choice for the owner and should not be assumed to be an automatic part of servicing.

Agree on approval and documentation

Ask for a cost estimate, parts availability, and schedule before proceeding. Agree on what happens if further problems are found during the work. Keep the service report and care instructions for future reference.

A breakdown of a watch service quote helps with comparison. For an inherited or collectible watch, discuss preserving original parts before any visible changes are made.
