A watch service interval is a planning guide, not a diagnosis of the watch on your wrist. Start with the maker’s instructions for the actual reference, then consider its condition and documented history. A routine inspection, battery replacement, water-resistance check and complete movement service are different jobs.
Use guidance for the actual watch
Rolex’s servicing FAQ recommends approximately ten years between services, depending on the model and real-life use. Tissot’s UK FAQ gives a general four-to-five-year servicing recommendation, with frequency depending on the model, climate and care. These examples concern the respective manufacturers’ watches, not a universal schedule for every movement.
Check which operation a recommendation describes. If your manual and a general support page give different guidance, ask the service centre which applies to your reference. With a used watch, an undocumented claim that it was recently serviced is less useful than an invoice stating the work completed.
Respond to changes before the calendar date
A sudden change in timekeeping, repeated unexplained stopping or difficulty operating a crown deserves advice before the next planned appointment. Describe the change without deciding that it must be magnetism, a worn part or a need for a complete overhaul. Do not force a resistant control.
For an otherwise normally functioning mechanical watch, a daily timing log can document a persistent change. Include wearing and winding conditions. Suspected water entry needs a more immediate response: follow our condensation guide rather than waiting to collect several days of readings.
Agree what the service will include
Ask for an assessment and written estimate before authorising work. Clarify whether the proposed service includes movement work, replacement seals, water-resistance testing, exterior cleaning or refinishing. A battery change should not be recorded as a complete movement service unless that additional work actually occurred.
Discuss polishing and replacement of visible parts before the watch is accepted for work, especially when preserving its existing finish matters to you. Ask the provider to record your preferences and explain any limits. Confirm the expected turnaround and how they will seek approval if the assessment reveals additional work.
Keep a record you can use next time
Retain the dated invoice, watch reference, provider’s details, work performed and any supplied test results. Record the service warranty separately from the original purchase warranty. Ask what follow-up checks are advised and what changes should prompt an earlier return.
When the watch comes back, check its functions as instructed and keep any observations with that paperwork. Clear records make the next maintenance decision easier than relying on memory or appearance. Explore Watches & Wear for further everyday ownership guides.
