What a watch actually costs to keep
Every guide in this category tells you what a watch costs. None of them tells you what it costs to keep. Here is that number, with the arithmetic shown.

The short answer
A Seiko with a 4R36 movement, serviced at Seiko's recommended three-year interval, costs $1,056 in servicing over twenty years — more than the watch. A 6R35 costs $1,776. A solar quartz watch, on the same horizon, costs a few hundred dollars at most. All figures are from published manufacturer price lists.
We checked ten competing pages in this category before building this site. Not one of them mentions a service interval, a service price, or a lifetime cost. Every one stops at the purchase price, which for a buyer who intends to keep a watch is roughly half the information they need.
So this page does the other half. Purchase price, plus the manufacturer's published service interval, plus the manufacturer's published service price, computed over ten and twenty years. Every input is a document you can open, and every assumption is stated before it is used.
The assumptions, stated up front
Arithmetic is only worth anything if you can see what went into it. Four assumptions, and where each comes from:
- Mechanical watches are serviced every three years. Seiko is the only manufacturer here that publishes an interval, and it recommends "about every three years". Hamilton states on its own service page that maintenance frequency depends on the model, the environment and the owner's care and that "it is therefore not possible to establish a precise maintenance frequency" — so we apply Seiko's figure across the board and label it as an assumption, not a fact about those brands.
- Twenty years means six services (at years 3, 6, 9, 12, 15 and 18). Ten years means three.
- Prices are the manufacturers' own current published figures, in the currency each publishes them in. Where a brand publishes no US price list, we say so rather than converting a European one and calling it a US cost.
- Straps, batteries, crystals and accident damage are excluded. They vary too much to model, and including a guess would undermine the point of the exercise.

What that table actually tells you
Three things, and they are all uncomfortable for the way this category normally writes.
- On a twenty-year horizon, servicing dominates the purchase price on every affordable mechanical watch. A Seiko 5 Sports costs roughly $200 to buy and $1,056 to keep. The purchase price is 16% of what you will spend on it.
- Stepping up from a 4R to a 6R costs $720 extra over twenty years, on top of the purchase price difference. Sapphire and 70 hours of reserve are real improvements; they also carry a running cost nobody mentions at the point of sale.
- Four of the eleven rows cannot be computed at all, because Citizen, Orient and Timex publish no prices. That is not us failing to find them — it is those manufacturers declining to say, and it is a legitimate reason to prefer a brand that does.
The case for solar, made by arithmetic rather than enthusiasm
A solar quartz watch has no recommended overhaul interval published by any manufacturer here. It is not wound and it takes no battery. The realistic cost over twenty years is one or two capacitor-related services.
Seiko lists V-series solar service at $163. Assume two of them in twenty years — an assumption, clearly labeled — and the total is $326 against $1,056 for a 4R36 and $1,776 for a 6R35. That is not close, and it is why a solar watch appears near the top of several lists on this site where a purely enthusiast-led guide would not put one.
What happens if you skip servicing
Most people do, and the watch does not stop the next day. Seiko's own explanation is the clearest statement of the mechanism: worn movement parts and aged oil cause a watch to lose time or stop, and separately, water resistance is not permanent — it degrades as gaskets age and as case parts deform from knocks.
So the practical failure is usually not a seized movement. It is a gasket that hardened five years ago letting water into a watch that its owner still believes is rated to 200m. That is why a partial service — $60 at Tissot, €60 at Hamilton, which is gaskets and a pressure test rather than a full overhaul — is the cheapest genuinely useful thing you can do to a watch you intend to keep.
The cheapest watches to keep, ranked
| Rank | What to buy | Twenty-year service cost | Why |
|---|---|---|---|
| 1 | A solar quartz with sapphire | ~$326 (assumed two services) | No winding, no batteries, no overhaul interval published by anyone |
| 2 | A Seiko on a 4R caliber | $1,056 | The cheapest published mechanical overhaul in the category |
| 3 | A Tissot on a Powermatic 80 | $1,260 | Slightly dearer, and Tissot warrants the work for 24 months |
| 4 | A Seiko on a 6R caliber | $1,776 | Better watch, meaningfully higher running cost |
| 5 | Anything with no published service price | Unknown | The bill arrives as a surprise, which is how watches end up in drawers |
How to use this before you buy
- Find the caliber name on the manufacturer's page. If there isn't one, you cannot do this arithmetic, and neither can anyone else.
- Look up that caliber on the maker's service price list. Seiko and Tissot publish one; most do not.
- Multiply by six for a twenty-year horizon. Add it to the purchase price. That is the real number.
- Then ask whether you want the mechanical option at all. The answer is often yes — but it should be a decision, not a default.
Questions people actually ask
How much does it cost to service an automatic watch?
It depends entirely on the caliber, and only two manufacturers here publish the figure. Seiko charges $137 for a 7S, $176 for a 4R, $296 for a 6R and $373 for an 8R. Tissot charges $210 for a complete service of a mechanical two- or three-hand watch, with a 24-month warranty on the work.
How often does an automatic watch need servicing?
Seiko recommends about every three years and is the only manufacturer here that publishes an interval. Hamilton states explicitly on its own service page that a precise frequency cannot be established because it depends on the model, environment and care.
Is it worth servicing a cheap automatic watch?
On pure arithmetic, a $176 overhaul on a $200 watch is hard to justify — but that is also the price of keeping something you like rather than replacing it. What makes it sane is that the price is published, so you can decide in advance rather than after a quote arrives.
Do quartz watches need servicing?
Not on an interval. They need batteries, and eventually the module is replaced rather than rebuilt. Seiko lists analog battery service at $100-135 and V-series solar service at $163, which over twenty years is a small fraction of any mechanical alternative.
What is a partial service?
Gaskets, a pressure test and a clean, without stripping the movement. Tissot charges $60 and Hamilton €60. It is the cheapest genuinely useful thing you can do to a watch you intend to keep, because water resistance degrades as gaskets age whether or not the movement is healthy.
Why can't you compute the cost for Citizen, Orient or Timex?
Because they publish no service prices. Citizen quotes every repair after inspecting the watch; Orient publishes no US list; Timex publishes no list and does not name the caliber on most of its automatics. We would rather report that than invent a figure.
