A Patek Philippe needs a complete service about every three to five years, and the cost depends on the calibre: a manual-wind or automatic Calatrava is the least expensive, a Nautilus or Aquanaut sits close to it, annual calendars and chronographs cost more, and perpetual calendars, minute repeaters and grand complications are quoted individually. Patek Philippe does not publish a price list; the watch is inspected at a Patek Philippe service centre and a written estimate follows. Turnaround is long, commonly several months and up to a year for complications, because Patek services every watch to the standard it was made to and makes parts for references it no longer produces. This guide sets out the intervals, what a complete service includes, how the cost bands sit against each other, what the two-year warranty covers, how long the work takes and why Patek service history matters at resale. Bizak & Co. sources Patek Philippe to order and discloses service history on every watch; the Patek Philippe collection lists the references we can seek.

How often should a Patek Philippe be serviced?
Patek Philippe's long-standing guidance is a complete service every three to five years, with the shorter end for watches worn daily and the longer end for watches worn in rotation. Water resistance should be checked more often on a Nautilus or Aquanaut that is swum in, because the gaskets age faster than the movement. A watch that has sat unworn for a decade is not exempt: lubricants dry and migrate whether or not the movement runs, and a first wind after years in a safe is when a dry pivot does its damage. Patek Philippe's stated commitment is that it can service and repair every watch it has made since 1839, which is why a vintage Calatrava can still go back to Geneva; the Patek Philippe collection pages describe the current references, and Patek's service centres and salons handle the rest.
What does a complete Patek Philippe service include?
| Level | What is done | When it applies |
|---|---|---|
| Check and water-resistance test | Rate and function check, gasket replacement, pressure test, external cleaning | Between complete services; annually for a watch that is swum in |
| Complete service | Movement fully disassembled, cleaned, worn parts replaced, lubricated, reassembled, regulated to Patek Philippe Seal tolerances and tested over several days; case and bracelet cleaned and, unless you decline, refinished; gaskets renewed; service warranty issued | Every three to five years, or when the watch shows the signs below |
| Restoration | Complete service plus remaking of parts no longer stocked, often in Geneva | Vintage references and complications |
Refinishing is the point to raise before the work starts. Patek's default is to restore the case and bracelet, which on a modern Nautilus or Aquanaut returns the brushing and polish to factory pattern; on a vintage Calatrava, collectors usually ask for the case to be left untouched to preserve the original edges and hallmarks. Say so in writing on the service order.
How much does Patek Philippe service cost?
Patek quotes after inspection, and the estimate depends on the calibre, the condition, the parts required and whether refinishing is included. The bands below describe how the costs sit relative to one another; they are not prices.
| Watch | Typical calibres | Relative cost of a complete service |
|---|---|---|
| Calatrava, manual or automatic | 215 PS, 30-255 PS, 324 S C, 26-330 S C | The base band; the least expensive Patek service |
| Nautilus and Aquanaut, time and date | 324 S C, 26-330 S C | Close to the base band; bracelet refinishing adds time on the Nautilus |
| Moon phase and power reserve | 240 PS IRM C LU | Above the base band; micro-rotor and additional modules |
| Annual calendar, travel time, chronograph | 324 S QA LU, CH 28-520, 26-330 S C FUS | Materially above a time-and-date service |
| Perpetual calendar, split-seconds, minute repeater | 240 Q, CHR 29-535 PS Q, R 27 and others | Quoted individually; several times the base band and often done in Geneva |
In practice a complete service on a simple Patek Philippe has been a four-figure US dollar cost in recent years, complications more, and grand complications well beyond that; replacement parts such as a dial, crystal, bracelet links or a Nautilus clasp are extra and can exceed the labour. Ask for the written estimate before agreeing to the work and ask for parts to be itemised. Gold and platinum cases cost more to refinish than steel.
What does the Patek Philippe warranty cover?
A new Patek Philippe carries a two-year international warranty from the date of sale on the Certificate of Origin, covering manufacturing defects; wear, accidental damage and routine service are not covered. A complete service at a Patek Philippe service centre carries its own warranty on the work, which is one reason a pre-owned watch with a recent Patek service receipt is worth more than one without. Patek does not reissue the Certificate of Origin, so keep it with the service papers; the Patek Philippe authentication guide explains what each document proves.
How long does a Patek Philippe service take?
Longer than any other major brand. A check and pressure test takes days; a complete service on a Calatrava, Nautilus or Aquanaut commonly takes four to eight months from drop-off to collection; annual calendars and chronographs longer; and perpetual calendars, minute repeaters and vintage restorations can take a year or more, especially when the work is done in Geneva and parts are made to order. Patek services are booked through Patek Philippe salons, authorised retailers and the regional service centres. If you are buying a watch to wear this year, a fresh Patek service receipt is worth paying for; if you are selling, do not send it in the month before.
Where should a Patek Philippe be serviced?
Patek Philippe's own service centres and authorised service points are the only source of genuine Patek parts, the only place a case will be refinished to Patek's pattern, and the only service that keeps the watch in Patek's records, which matters if you later request an Extract from the Archives or sell at auction. An independent watchmaker can clean and lubricate a 324 or a 215 competently and more quickly, but cannot obtain a genuine dial, hands or bracelet parts, and a non-Patek service on a complication is a deduction at resale. For anything vintage, complicated or with a display back, use Patek. Our Patek Philippe price guide explains how service history moves a quote.
Service costs by Patek Philippe line
| Line | What drives the cost | Points to raise |
|---|---|---|
| Calatrava | Simple calibres; gold case refinishing | Decline refinishing on vintage; ask about hallmarks |
| Nautilus | Bracelet refinishing; clasp and pin replacement; date and moon-phase modules on the 5712 and 5726 | Ask whether bracelet links are replaced or refinished; keep the original screws; the Patek Philippe Nautilus collection lists the current references and calibres |
| Aquanaut | Composite strap replacement; water-resistance renewal | Budget a new strap with each service; the Aquanaut 5167 guide covers strap sizes |
| Complications | Calendar and chronograph modules; testing time | Ask for the estimate to separate movement work from case work |
| Grand Complications | Repeater gongs, split-seconds mechanisms, Geneva workshop time | Expect a bespoke quote and a long timeline |
Signs a Patek Philippe needs a service
- Rate. Drift beyond what it did when new; Patek regulates its Seal calibres to within a few seconds a day.
- Power reserve. A watch that stops sooner than it should; the 324 and 26-330 are rated around 45 hours and the 240 around 48.
- Winding and setting. Grit or resistance in the crown, a date or calendar that hesitates, a moon phase that lags.
- Moisture. Fogging under the crystal; stop wearing the watch and book a service.
- Age. Five years since the last complete service, or no record of one.
Buying a used Patek Philippe: service checks
- Service receipts. Patek Philippe paperwork listing the work, parts replaced and the service warranty date.
- What was replaced. A dial or hands Patek replaced is fine if disclosed; on a vintage watch it changes the price materially.
- Refinishing. Crisp case edges and hallmarks on vintage; factory-pattern brushing and polish on a modern Nautilus. Rounded edges mean a poor refinish that no later service can undo.
- Certificate of Origin. Present and matching the case and movement numbers; it cannot be replaced.
- Budget. If there is no service record, price in a complete Patek service and the months without the watch.
- Price against the band. A full-set Nautilus or Calatrava offered well under the market is the single most reliable warning sign.
Our authentication process describes what we inspect before dispatch. On September 21, 2026 Bizak's sourced catalogue listed a Calatrava 6119G-001 at US$33,681, an Aquanaut 5167A-001 at US$86,519 and a Nautilus 5712/1A-001 at US$89,100, all sourced to order; a complete service every four years is a low single-digit percentage of any of those values per cycle. Those figures describe what we saw and will move.
