What Watch Servicing Costs and When You Need It

A mechanical watch needs a full service every several years, a quartz watch needs a battery change every few years, and the cost depends mostly on the movement type, the brand, the condition of the parts and who does the work. A service is not a polish: the watchmaker takes the movement apart, cleans it, replaces worn parts, lubricates it, reassembles it, adjusts the timing and tests water resistance. Rolex says on its own site that its watches should be serviced about every 10 years, depending on the model and use. This guide explains intervals, what you pay for, how to spot trouble and what to ask when you buy a pre-owned watch.

Why watches need servicing at all

Watches run for years without a person looking inside, so it is easy to assume they do not need attention. They do, for three reasons.

• Oil breaks down. A mechanical movement is lubricated at its pivots and contact points. Over time the oil thickens, migrates or dries, and friction rises. Higher friction means lower amplitude, worse timekeeping and faster wear on parts.
• Seals age. Gaskets are rubber or synthetic rings. They harden, flatten and crack, and the water resistance on the dial is only as good as the seals. Opening a case also disturbs them.
• Parts wear. Pivots, gears and the mainspring wear slowly. A service lets the watchmaker replace parts before they damage others.

A watch can keep running while all of this happens, which is why waiting too long often turns a routine service into a larger repair.

How often by movement type

There is no single number. The figures below are general guidance from watchmakers, so treat them as estimates and check your maker's own recommendation.

Our guide Automatic vs Quartz Watches: The Real Difference explains why the two families age so differently, and our guide Watch Movement Types Explained covers solar, kinetic and Spring Drive in more detail.

Two practical notes. First, many brands publish their own interval, so the maker's website or manual is the better source than a general rule. Second, a watch worn every day in dusty, humid or sweaty conditions may need attention earlier than a watch worn on weekends.

What a full service includes

A typical full service on a mechanical watch is an overhaul, often called a complete service or COSC-style service when it is done by the brand. The steps are:

1. Inspection and quote. The watchmaker opens the watch, checks condition and gives you an estimate before doing anything beyond basic work. Rolex says on its site that you approve a cost estimate before the work begins.
2. Disassembly. The movement is taken apart down to individual parts.
3. Cleaning. Parts are cleaned in baths to remove old oil and debris.
4. Parts replacement. Worn components, such as gaskets, crystals, crowns, tubes and mainsprings, are replaced as needed.
5. Lubrication. Each pivot and contact point is oiled with the correct lubricant.
6. Reassembly and regulation. The watch is rebuilt and adjusted to run accurately in several positions.
7. Water resistance test. The case is tested on a pressure tester. This is the step buyers most often forget to ask about.
8. Case and bracelet refinishing. Some brand services include cleaning and refinishing. Others offer polishing as an option. Polishing removes metal, so ask first.

A quartz service is simpler: the watchmaker replaces the battery, checks the movement, replaces the gaskets if needed and pressure tests the case. Many quartz watches are inexpensive to maintain for this reason.

What drives the cost

Quotes vary by brand, region, parts and the watch's condition. These are the factors that move a quote.

• Movement type. Quartz is the least expensive to maintain. Mechanical watches take more labor. Complications such as chronographs, perpetual calendars and minute repeaters take the most.
• Brand and who does the work. An official brand service center, an authorized retailer's workshop and an independent watchmaker price the work differently. Brand service usually uses genuine parts and may carry a service guarantee. An independent can be less expensive but may use aftermarket parts. Neither is automatically better, so ask what parts will be used and what guarantee you receive.
• Parts needed. If the watch has been neglected, the watchmaker may find damaged components. Original parts for vintage or discontinued models can be scarce.
• Case material. Precious metals do not change the movement work but can change refinishing and handling choices.
• Turnaround. Brand centers can take weeks or longer. Rolex says a complete overhaul takes at least four to six weeks, depending on condition. Independent shops vary.
• Optional extras. Polishing, bracelet refinishing and strap replacement are separate from the movement service.

Ask for a written estimate and for the quote to list what is included. Rolex publishes service guidance on its website, but we did not find an official public price list for services, so any figure you see elsewhere for a Rolex service is an estimate from a third party. Always get a quote from an official Rolex service center or authorized retailer.

Rolex-type brand service

Brand service on a luxury watch is a different experience from a neighborhood battery change. For Rolex specifically, the official guidance on its site includes these points:

• The watch should be serviced approximately every 10 years, depending on model and real-life use.
• Rolex-certified watchmakers evaluate the watch first and you approve a cost estimate before work begins.
• A complete overhaul takes at least four to six weeks, depending on condition.
• A serviced watch comes back with a Rolex Service Card and a service guarantee. Check the current terms on Rolex's own site.

Other major brands, such as Omega, Seiko, Grand Seiko, Tudor and Cartier, publish their own guidance and pricing policies, so check each maker's site. If you own a watch from a brand with a quoted fixed price, that is an official price. If a price comes from a forum or a retailer blog, treat it as an estimate.

Signs a watch needs service

Not every watch gives a warning, but these are common signs.

• It gains or loses a lot of time. A mechanical watch drifting by minutes a day is a sign the movement needs attention. A fresh service often restores timekeeping.
• It stops when worn lightly. If it runs only when fully wound or when you shake it, the lubricants or parts may be worn.
• The power reserve is short. A watch that used to run for a couple of days now stops after several hours.
• The crown feels gritty or loose. A rough winding feel or a crown that spins freely points to mechanical wear.
• The date or chronograph acts up. Sluggish pushers, a chronograph hand that jumps or does not reset to zero, and a date that fails to change at midnight are common faults.
• Moisture or fogging. Condensation under the crystal means the seals have failed. Stop wearing the watch and have it checked promptly, because water damage is the costliest kind.
• A battery that dies unusually quickly on a quartz watch can indicate an electrical fault.
• Unusual noise, such as a rattling rotor or a buzzing sound.

If you spot any of these, ask a watchmaker for an evaluation. A diagnosis does not commit you to a repair.

What to ask when buying a pre-owned watch

Service history is one of the most useful questions you can ask. Before you buy, ask the seller:

1. When was it last serviced, and by whom? Ask for paperwork, such as a service card or invoice, if it exists.
2. What movement does it have? The answer tells you what service it will need. Our guide Watch Movement Types Explained helps you interpret it.
3. What was replaced? Gaskets, crystal, crown and mainspring are meaningful.
4. Is the water resistance pressure tested? A dial that says 100 meters does not mean the watch can handle it today.
5. Is the dial, hands and case original? Replaced parts can affect value and a brand's willingness to service it.
6. How does it keep time? A recent timing result or a short video of the seconds hand is useful.
7. Does it come with the box and papers? They can speed up a brand service.
8. What is the return window? If you can have the watch inspected, a good seller will allow a reasonable time to do so.

Our guides How to Authenticate a Luxury Watch and How to Authenticate a Rolex cover what to check beyond service, and Do Rolex Watches Hold Their Value? explains how service history and originality can influence value. Budget for a service as part of the true cost of a mechanical watch you are about to buy, because the next one may be due soon.

Seeing and asking live

You can ask these questions in real time when a seller is live. On ShopBidz, Ziv Tamir of Rocks On Clocks LLC in Miami, Florida, and NYC Watches & Diamonds in New York, NY, sell watches live. You can watch the second hand, ask about service history and request a close look at the case back before you bid.

Common mistakes

• Waiting until the watch stops. A watch that has run dry can cause wear to parts, so a service that was due can become a repair.
• Choosing the lowest quote without asking what is included. Pressure testing, new gaskets and a guarantee can be left out of a bare estimate.
• Polishing automatically. Polishing removes metal and can soften edges. Say no unless you want it.
• Skipping the water test after a battery change. An opened case is only as water resistant as the last seal check.
• Assuming a recent service means a good service. Ask who did it and what was replaced.

Bottom line

Servicing cost depends on the movement, the brand, the parts needed and who does the work. Quartz is the simplest and least expensive, mechanical watches need periodic overhauls, and complications and brand service sit at the high end. Rolex itself recommends about every 10 years, depending on the model and use. Ask for a written estimate, keep the paperwork, watch for signs of trouble, and ask any seller for service history before you buy a pre-owned watch.
