There is no single service interval that fits every watch. The maker’s guidance, the model and movement, and how the watch is worn all matter. Water resistance can also decline, magnetism may affect timekeeping, and cosmetic work such as polishing should follow the relevant brand’s advice. Here are seven practical answers, grounded in watchmakers’ and manufacturers’ published guidance.
1. How often should a watch be serviced?
Follow the manufacturer’s recommendation for the specific watch, rather than treating any one interval as an industry-wide rule. Published guidance varies:
| Brand | Published recommendation | Qualification |
|---|---|---|
| Rolex | Approximately every 10 years | Depends on the model and real-life usage. Rolex service FAQ |
| Patek Philippe | Every 8 to 10 years | Applies to its quartz and mechanical watches. Patek Philippe watch care |
| Seiko | About every 3 years | Frequency can be affected by climate and individual care. Seiko service interval guidance |
| Victorinox | Every 18 to 24 months | Recommends authorized service. Victorinox watch FAQ |
| Carl F. Bucherer | No standard interval stated | Timing depends on model, climate, wearing and treatment. Carl F. Bucherer FAQ |
These are brand-specific recommendations; they are not a shared schedule for all watches. The cited pages do not state publication years for these recommendations, so the figures should not be read as dated industry statistics.
2. Does a watch need servicing if it still keeps time?
Not necessarily, but accurate timekeeping alone does not establish the condition of every component or seal. Rolex says a Rolex-trained watchmaker performs a diagnostic examination before service, while Jaeger-LeCoultre describes checks that can assess magnetism, accuracy and water resistance. The appropriate check depends on the issue: routine servicing, a timing concern and a water-resistance check are different needs.

3. Is a watch’s water-resistance rating permanent?
No. Water resistance is a condition to monitor, not a lifetime guarantee. TAG Heuer says it cannot be permanently guaranteed and recommends a check every two years for watches regularly exposed to water. That two-year recommendation is TAG Heuer’s guidance for that exposure context, not a universal interval.

If the watch is routinely exposed to water, ask an authorized service provider about checking its condition.

4. Can magnetism make a watch run fast or slow?
Yes, depending on the movement. Seiko says a magnetized mechanical watch may gain or lose time and can remain magnetized after it is taken away from the source. Its customer-care FAQ states: “A mechanical watch affected by magnetism remains magnetized even after removing it from the magnetic source.”
Seiko’s guidance distinguishes movement types: analog quartz watches with step motors may be affected, while its FAQ describes digital quartz watches as generally unaffected because they have no motor. For an affected watch, Seiko recommends demagnetization at an Authorized Seiko Service Center rather than promising that a generic consumer device will fix it. Seiko magnetism FAQ

5. What can a watchmaker check when a watch seems inaccurate?
A professional check can help identify whether magnetism, accuracy or water resistance needs attention. Jaeger-LeCoultre notes that magnetic fields, shocks and humidity can affect the precision of mechanical or automatic watches over time. Rolex describes a diagnostic examination by a Rolex-trained watchmaker before service.
Those examples show why a timing complaint is worth assessing rather than assuming it requires a complete service. They do not establish that every brand uses the same diagnostic process. Jaeger-LeCoultre maintenance and check information; Rolex service FAQ

6. Should a watch be polished during service?
Polishing is not automatically necessary, and the cited guidance does not support calling it always harmful or always beneficial. Rolex says professional polishing of its watch cases and bracelets should only be performed by an Official Rolex Service Center. Treat this as Rolex-specific advice; check the maker’s instructions for other watches.
7. How should you choose the right service or check?
Start by identifying what the watch needs instead of treating every concern as a full-service question. These details help narrow the next step:
- Maker and model: Find the model-specific care instructions and service interval.
- Movement type: Mechanical, analog quartz and digital quartz watches may respond differently to issues such as magnetism.
- Use and condition: Consider water exposure, impacts, climate and how often the watch is worn.
- Specific concern: Separate routine service from a water-resistance check, a timing issue, suspected magnetism or cosmetic work.
- Provider: Confirm whether the provider is authorized for the brand, especially when the manufacturer directs owners to authorized service.
Manufacturer guidance supports comparing those factors, but does not establish comparative prices, turnaround times, warranties or service quality for different providers.
