How often should an automatic watch be serviced?
Every shop quotes a different number, and the brands themselves disagree by years. Here is what the big names actually publish, the signs that override any interval, and the one case where the sensible answer is to leave the watch alone.
Short answer
Most watchmakers and retailers quote a full service for an automatic watch every three to five years. The brands are less uniform: Seiko’s own guidance is around three years, Omega publishes five to eight, and Rolex says roughly ten for a modern watch in normal use. Treat the interval as a reminder to pay attention, not a deadline — how the watch behaves matters more than the calendar.

Why an automatic watch needs servicing at all
An automatic movement is a crowded stack of metal parts rubbing against each other several times a second, kept apart by tiny quantities of oil placed at specific points during assembly. Those oils are the whole reason a service exists. Over years they thicken, creep away from where they were put, or pick up dust and metal particles, and once a bearing is running dry the pivot wears instead of the oil.
That is why a service is a strip-down rather than a top-up: a watchmaker disassembles the movement, cleans every part, replaces what has worn, re-oils, reassembles and regulates the rate. It is also why the job is priced as skilled hand work, and why an owner who has never had it done is often surprised by the quote.
One thing worth settling first: this only applies if the watch really is mechanical. A quartz watch has a battery and a service story of its own. If you aren’t certain which you have, the seconds hand usually gives it away — our guide to telling whether a watch is automatic or quartz covers the test and the exceptions.
What Rolex, Omega and Seiko publish
These are the figures the brands put in front of customers, as of October 2026. Brands revise them, and each one is written for watches used normally rather than dived with every weekend, so read them as the manufacturer’s starting point.
| Brand | Published interval | What it rests on |
|---|---|---|
| Rolex | About every 10 years for a current-generation watch | The longer figure is attributed to newer synthetic lubricants, gaskets and tolerances. Dealers and independents commonly advise a shorter cycle — often five to seven years — for a watch worn daily or for a vintage reference |
| Omega | A full service every 5 to 8 years, plus a water-resistance check every year | The wider interval is generally attributed to its Co-Axial movements, which are designed to reduce friction. Older non-Co-Axial calibres are generally put nearer the five-year end |
| Seiko | Around every 3 years at an authorised service centre; some model instructions say an overhaul roughly every 3 to 4 years | Seiko’s customer-service material frames it as oil degradation and the wear that follows once oil is contaminated |
Figures summarised from each brand’s customer-service material and from service specialists quoting it. Your watch’s own instruction booklet, or the brand’s service page for your reference, is the authority for your particular model.
The spread is the useful part. A ten-year interval and a three-year interval are not a disagreement about physics; they describe different movements, different oils and different tolerance for a watch drifting out of spec. If you only remember one thing, remember that the number belongs to the model, so you need to know which model you have before any interval applies to you.
Signs your watch needs a service before the interval is up
Any of these outranks the calendar. None of them is a diagnosis — they are reasons to put the watch in front of a watchmaker.
- The rate has changed. Not “it isn’t perfect” — mechanical watches never are — but a clear shift from the rate your watch has always kept, in either direction.
- It stops early. A fully wound movement that gives up well before its usual power reserve is losing energy somewhere it shouldn’t.
- It winds badly. The rotor feels loose or noisy, or a day on the wrist no longer keeps it running.
- The crown feels wrong. Gritty, stiff, or vague when you set the time.
- Moisture. Any misting under the crystal is urgent, not a wait-and-see. Water inside a case does not dry out harmlessly; steel parts corrode while you think about it.
- It has been dropped, or it rattles. Shock damage doesn’t respect service intervals.
A watch that has been sitting in a drawer for years and is now running badly doesn’t need winding advice — it needs someone to open it. Running a movement with dried oil is the one thing that turns a service into a repair.
Does a watch you never wear still need servicing?
Partly. The oils age on their own: time, temperature and contamination do their work whether or not the balance is swinging, so a watch stored for a decade does not come out with a fresh movement. What a stored watch avoids is wear, which is the expensive half of the problem.
The practical answer most watchmakers give is this. A watch you genuinely never intend to run can be left as it is; nothing breaks while nothing moves. A watch you plan to wear again should be serviced before you start relying on it, rather than after a few months of running on oil that gave up years ago. If you are the person who has just opened a drawer full of them, our guide to what to do when you have inherited a watch covers the order to do things in.
Water resistance is a separate, yearly check
The seals that keep water out are rubber gaskets at the crown, the caseback, the crystal and any pushers, and they harden with age, heat and contact with chemicals. Because they degrade on their own schedule, brands treat the pressure test as an annual item rather than something that waits for the full service — Omega’s guidance puts the water-resistance check at once a year.
A pressure test is quick and cheap next to a service, and it is the only honest way to know whether a rating stamped on the caseback in 1998 still means anything. The rating itself describes the model when it left the factory; the markings on the back tell you what that rating was, not what the watch can do today. What each figure permits in the first place is a separate question: what watch water resistance ratings actually mean.
When a service costs more than the watch is worth
This is the question behind most searches about intervals, and it deserves a straight answer: a full strip-down is skilled labour, and for plenty of ordinary watches the quote can approach or exceed what the watch would sell for. That isn’t a reason to skip it — it is a reason to find out what you have first, in this order.
- Identify the watch precisely. Brand, model and reference, not just “an old Seiko”. The reference is what service pricing, parts availability and interval guidance are all keyed to. Here is where each brand hides it.
- Find out roughly what it is worth. Sold prices, not asking prices — our guide to what a used watch is worth explains the difference and where to look.
- Get a quote before you commit. Authorised service centres and good independents will both estimate; the brand route is usually dearer, and if the watch is collectable it is worth asking in advance what gets replaced rather than repaired.
- Then decide. Sentimental watches get serviced regardless. For everything else, a watch worth a little and quoted a lot is allowed to sit in a drawer, unharmed, until you want it running.
Whatever you decide, write the date down. A service record is one of the few pieces of paperwork that still matters years later, both to the next watchmaker and to a buyer — our guide to cataloguing a watch collection lists what else is worth keeping with it.
What Loupe does and doesn’t do here. Loupe identifies the brand, model and reference from a photo and gives a confidence rating, plus an estimated resale range that is clearly labelled as not an appraisal. That is the information step: the name to look your service interval and your parts up under, and a rough sense of what the watch is worth before you book. Loupe is not a watchmaker — it cannot see inside the case, it does not know when your watch was last serviced, and it does not authenticate watches. Saving a watch to your collection gives you a notes field, which is a reasonable place to keep the date of the last service; the collection stays on your phone.
