How Often Should a Mechanical Watch Be Serviced?

Keep a written record of the exact model reference, seller description and warranty terms. When a claim is model-specific, confirm it in the current instruction manual or on the manufacturer's official support page.

Common mistakes to avoid

• Waiting through visible moisture or grinding because a calendar interval has not arrived.
• Servicing too frequently without need or evidence.
• Choosing a provider who cannot explain parts, testing or warranty.

If information is missing or contradictory, pause the purchase or use. A cautious answer based on the exact model is more useful than a confident guess.

A simple decision rule

Choose the option that meets your normal use with the fewest unsupported assumptions. Pay for features you understand and will use. For water exposure, repairs, battery replacement, pressure testing or movement problems, follow the manufacturer and use a qualified service professional.

Frequently Asked Questions

Should I service a watch that runs well?

Preventive guidance varies; follow the maker and consider seals, age and use, not rate alone.

Will service remove scratches?
