There is a particular kind of silence a stopped watch makes. You tap it, shake it, wind it a little, and nothing happens. Then comes the practical question: take it to a bench, or take it off your wrist for good?

Most people settle this on instinct, and instinct usually favours whichever option involves less hassle. That is a pity, because the choice is more interesting than it looks. A watch that seems beyond saving can often be brought back for less than you expect, and a watch you love can turn out to be genuinely uneconomical to fix. Before you decide, do two things: find out what actually failed, and work out what the watch is worth to you — not to a marketplace, to you.

Find Out What Actually Failed

Repair or replace is not one decision. It is a series of smaller ones, and the first is diagnostic. A quartz watch that has stopped may need a battery, or it may have a failing coil, a fouled movement, or a stem that no longer engages properly. A mechanical watch losing two minutes a day is usually not broken, just overdue for a service. One that stops at random may have a worn rotor bearing, or hands rubbing against a slightly loose crystal.

Any competent watchmaker can open the case, test the circuit or inspect the movement, and tell you which of those you are dealing with, often in a few minutes. Ask for the diagnosis in plain language, and for the estimate in writing, with parts and labour separated. Two details are worth insisting on: whether the price includes a new gasket and a pressure test, and what warranty covers the work. A repair without a water-resistance check on a watch you swim with is only half a repair.

If the watch is valuable, get a second opinion. Not because watchmakers are dishonest, but because labour rates, parts access and willingness to work on older calibres vary enormously from bench to bench.

The Money Question, Framed Properly

The comparison that matters is not "repair cost versus the cheapest new watch you can find". It is repair cost versus a like-for-like replacement: comparable movement, comparable case finish, comparable water resistance. A twenty-year-old diver with a solid case and a serviceable movement is not really competing with a fashion watch from a department store shelf.

Servicing a mechanical watch is slow, skilled work. A full service generally means complete disassembly, cleaning, fresh lubrication, replacement of worn parts, reassembly, timing and testing. That is why the bill can look large next to what you originally paid, particularly on an entry-level automatic where the labour is a big share of the watch's value.

A rough rule many owners find useful: if a straightforward repair costs more than about half of what an equivalent new watch would run you, and the watch carries no sentimental weight, replacement deserves serious thought. Below that line, repair usually wins. Above it, the decision turns on the next two sections.

Cheap quartz watches are their own case. A movement swap is often quick and inexpensive, and it restores the watch completely rather than patching it. A battery change is cheaper still — but only if you catch it early. A leaking cell can destroy a movement in weeks, which is why a five-year-old battery in a drawer is a small gamble.

Do not forget the costs that never appear on the estimate. A replacement resets the clock on servicing, and a repaired watch comes back with a known history and a warranty on the work. There is salvage value too: a worn-out watch can donate a bracelet, a crown or a movement to keep a sibling running.

Sentimental Value Is a Real Variable

Sentiment does not change the invoice, but it absolutely changes the decision. A watch inherited from a grandparent is not competing with a shop window; it is competing with the idea of not having it any more. If you would never sell it, its market value is irrelevant to the calculation and you should stop pretending otherwise.

That said, be honest about the strength of the attachment. A watch bought on a whim during a holiday and never worn since is not an heirloom, and treating it as one leads to expensive repairs of things you will not use.

Where sentiment is genuine, there is often a middle path: keep the parts that carry the memory and renew the parts that do not. Retaining the case and dial while replacing a tired movement is a common and sensible compromise. Ask for minimal intervention. Polishing removes metal and softens case lines permanently, and a refinished dial can strip value and character in one go. A good watchmaker will tell you what not to touch.

Repairability: Some Watches Are Built to Be Fixed

Signs a watch will cooperate

• A common, well-documented movement with parts still in production or plentiful in donor watches.
• A brand that still services its older models, or an independent specialist who knows the calibre.
• A screw-down caseback rather than a sealed, glued or press-fit one.
• Standard crystal shapes and gasket sizes that any parts house stocks.
• Damage confined to wear items: crystal, crown, gasket, spring bars, bracelet pins.

Signs it will fight you

• An obsolete in-house movement with no parts supply and no donor market.
• Water damage that has left corrosion across the movement, not just on the caseback.
• A plastic or sealed movement designed to be discarded rather than serviced.
• Smartwatches and hybrids, where "repair" usually means a module swap and software support may end long before the hardware does.
• Cracked or badly worn case threads, which can rule out restoring water resistance.

Ask directly before authorising anything: are the parts available, and how long will they take to arrive? A watchmaker who hesitates on that question is telling you something useful.

When Replacement Is the Sensible Answer

Replacement is not a defeat. It is the right call when the movement is unobtainable, when corrosion has spread through the gear train, when the case cannot be made watertight again, or when the repair bill approaches the price of a better watch than the one on the bench. It is also the right call when the watch simply does not suit your life any more: a dress watch that lives in a drawer is not improved by a service.

Even then, keep the old one. A drawer of donor parts costs nothing and occasionally saves a fortune.

A Practical Decision Checklist

1. Get a diagnosis, not a guess. Battery, movement, damage, wear — know which.
2. Ask for a written estimate that separates parts and labour and states the warranty.
3. Price a like-for-like replacement before you judge the repair as expensive.
4. Set your ceiling in advance. Decide the number you would pay before sentiment gets a vote, then allow yourself to break it only for a reason you can name.
5. Check parts availability and turnaround, especially for anything over fifteen years old.
6. Choose the scope deliberately. Movement service only, or movement plus crystal and gasket, or full cosmetic work. Each tier has its own price.
7. Confirm water resistance testing if the watch goes near water.

Keeping the Survivor Running

Whatever you decide, the following years are cheaper than the ones that just ended. Change quartz batteries before they leak rather than after. Have gaskets checked whenever the case is opened, and have the watch pressure-tested if you swim in it. Keep mechanical watches away from strong magnets, hot cars and household chemicals, and wear them regularly or wind them on a routine so the lubricants stay distributed. A service every five to seven years, or whenever timekeeping drifts noticeably, is far cheaper than waiting for a broken part.

Finally, keep the paperwork. Receipts, service records and the original box make a future repair easier to justify and a future sale easier to arrange — and they are the difference between a watch that has a history and one that merely has a past. If a repair estimate represents real money for you, treat it like any other significant purchase: written quotes, a clear scope, an agreed warranty, and no pressure to decide on the spot.
