Most makers recommend servicing an automatic watch somewhere between every 3 and 10 years, depending on the brand, the movement and how you use it. Rolex recommends approximately every 10 years. Omega recommends a complete service every 5 to 8 years. Seiko asks for a visit once every three years. Grand Seiko suggests about every 3 to 4 years.
Those numbers are not deadlines. All four makers say that use and environment change the interval. A watch that runs well, holds its power reserve and keeps time within spec can often go longer; one that starts losing time or stopping needs attention sooner. Here is how to decide.
How often to service an automatic watch, by brand
| Brand | Recommended interval | Notes from the maker |
|---|---|---|
| Rolex | Approximately every 10 years | Depending on the model and real-life usage |
| Omega | Complete service every 5 to 8 years | Water resistance checked once a year; depends on use and environment |
| Seiko | Once every three years | For examining, cleaning and oiling of parts where needed |
| Grand Seiko | About every 3 to 4 years | Disassembly, cleaning and adjustment |
For other brands, check the warranty booklet or the maker's customer-service pages. If there is no figure, use the ranges above as a reference and let your watch's behavior guide you.
What a service includes
A full service, sometimes called an overhaul, usually covers:
- Inspection and timing. The watchmaker checks rate, amplitude and power reserve on a timegrapher. Our guide to reading rate, amplitude and beat error explains those numbers.
- Disassembly. The movement comes out of the case and is taken apart.
- Cleaning. Every part goes through a cleaning machine to remove old oil and dirt.
- Replacement of worn parts. Mainspring, gaskets and any worn wheels or springs.
- Reassembly and lubrication. Fresh oils and greases at each friction point.
- Regulation. The rate is adjusted in several positions.
- Case work. Gaskets are replaced and the case is pressure-tested for water resistance. Refinishing the case and bracelet is often offered as an option. Between services, see our guide to cleaning a watch without damaging it.
- Final testing. The watch is checked over several days before it goes back to you.
A partial service or water-resistance check covers only some of these steps. Omega's advice to check water resistance once a year is a good habit for any watch you swim with.
Warning signs your watch needs a service now
- It loses or gains much more than it used to. Rule out magnetism first; our guide to an automatic watch running fast explains how.
- The power reserve is shorter. A watch that used to run two days off the wrist now stops overnight. See automatic watch power reserve for how to measure it.
- It stops on the wrist or soon after a full wind.
- The crown feels gritty or rough when you wind it.
- The date changes slowly or sticks.
- Moisture or fog under the crystal. Get this seen quickly; water damages a movement fast.
- After a hard knock or a drop.
- The rotor is noisy or scrapes, or you feel it knocking against the case.
How often to service popular brands
Seiko and Orient
Seiko's US customer service says to bring a watch in once every three years for examining, cleaning and oiling. For entry-level Seiko and Orient automatics, many owners wait until the watch shows a symptom, because a full service can cost a large share of a new watch. Get a quote and ask whether a movement replacement makes more sense.
Omega
Omega recommends a complete service every 5 to 8 years and a yearly water-resistance check. If you keep an Omega on a winder, the settings are in our watch winder for Omega guide.
Rolex
Rolex recommends servicing approximately every 10 years, depending on the model and use. Rolex owners who rotate several watches often use winders; see our watch winder for Rolex guide.
Grand Seiko
Grand Seiko's guidance is about every 3 to 4 years for disassembly, cleaning and adjustment.
Tissot, Hamilton and other Swatch Group brands
Check the warranty booklet or the brand's service pages for the interval that applies to your model. Modern movements with long power reserves, such as Tissot's Powermatic 80 and Hamilton's H-10, are serviced like any automatic.
How long does an automatic watch last?
With regular servicing, decades. Mechanical watches from the early 20th century still run today because they were serviced and repaired over the years. Three things decide how long yours lasts:
- Servicing. Fresh oils and new gaskets prevent most long-term wear.
- Parts availability. Big makers keep parts for many years. Small or defunct brands may not.
- Use. Shocks, water exposure and magnetism shorten the time between services.
Does a watch winder affect service intervals?
A winder runs the watch the same way daily wear does, so the movement is working whenever it is on the winder. Makers base their intervals on normal use, so a watch on a winder sits in the same category as one you wear every day. A watch that sits stopped in a drawer is not wearing its parts, but its oils still age. We look at the arguments in are watch winders bad for watches.
How to make the time between services longer
- Keep it wound and running steadily. A watch that runs in the healthy middle of its power reserve is under less stress than one that keeps stopping and starting from empty.
- Avoid shocks. Seiko recommends taking a watch off for sports with strong impacts.
- Keep it away from magnets, which upset timekeeping and send many watches to the watchmaker unnecessarily.
- Rinse it after salt water and keep the crown screwed down or pushed in.
- Check water resistance yearly if you swim with it.
- Store it properly when not in use: dry, separated and out of the sun.
A closed-lid watch box covers the last point: each watch gets its own cushion and stays out of direct light.
Service vs repair: what to expect
| Situation | What it is | Typical outcome |
|---|---|---|
| Routine service on a healthy watch | Cleaning, oiling, gaskets, regulation | Back to factory-like performance |
| Service after years of neglect | Same, plus worn parts replaced | Longer turnaround, higher cost |
| Water damage | Rust removal, many parts replaced | Can be major; act quickly |
| Shock damage | Balance staff, hairspring or other parts | Depends on the part |
| Magnetized watch | Demagnetizing and a rate check | Usually quick, no service needed |
How to choose where to service it
- The brand's service center: original parts, the maker's warranty on the work, and usually the longest turnaround.
- An authorized dealer: often sends the watch to the brand's service center.
- An independent watchmaker: often faster and cheaper, and many are excellent. Ask about parts, warranty and whether they have access to the brand's parts.
Whichever you choose, ask for a written estimate first, and say whether you want the case polished. Some collectors prefer to keep original finishes unpolished.
Common mistakes
- Waiting until the watch stops. By then, worn parts may need replacing.
- Skipping water-resistance checks on a watch you swim with.
- Polishing a vintage case without asking for it.
- Assuming a winder replaces servicing. It keeps the watch running; it does not replace oils.
- Treating the interval as a fixed rule. It is a guide; symptoms matter more.
FAQ
How often should an automatic watch be serviced?
It depends on the maker. Rolex recommends approximately every 10 years depending on the model and use, Omega a complete service every 5 to 8 years, Seiko once every three years, and Grand Seiko about every 3 to 4 years. All of them say use and environment affect the interval.
What happens if you never service an automatic watch?
Oils dry and thicken, parts wear faster, and gaskets lose their seal. The watch will usually start losing time, show a shorter power reserve and eventually stop. Worn parts can turn a routine service into a more expensive repair.
How long does an automatic watch last?
With regular servicing, a well-made automatic can run for decades and be passed down. Without servicing, wear accelerates. The movement's quality and the availability of parts matter as much as age.
Is it worth servicing a cheap automatic watch?
Sometimes not. For inexpensive mass-produced movements, a full service can cost close to, or more than, a replacement movement or watch. Ask a watchmaker for a quote and whether a movement swap is an option.
Does a watch winder mean I need to service my watch more often?
A winder keeps the movement running, the same as wearing it daily. Makers base their service intervals on normal use, so a watch on a winder is in the same position as one you wear every day.
