Audemars Piguet Royal Oak Service Guide: Costs, Intervals and Polishing Limits

Audemars Piguet doesn't publish a fixed overhaul interval on its service pages. What it does recommend is a yearly check: chronometric performance, functions, water resistance and magnetisation are all looked at, and the check is offered free in its boutiques. AP is explicit that this check-up isn't warranted, so think of it as a health screening rather than a repair.

For a watch you wear regularly, that annual look is the sensible rhythm, with a full overhaul when the check shows the watch drifting out of tolerance, running with a weak power reserve, or when the case seals are due.

If you've bought a pre-owned Royal Oak and have no service paperwork, treat it as unserviced and budget for an overhaul. Dealer language like 'recently serviced' means little without an invoice that names who did the work and what was replaced.

AP's price list describes the complete maintenance as opening the watch, prewashing the movement and dismantling every component of the movement. From there it follows the standard pattern for a quality mechanical watch: cleaning, inspection, replacement of worn parts, lubrication, reassembly and regulation.

The case and bracelet are part of the picture too. AP says complete maintenance includes replacing worn functional case and bracelet parts. The water-resistance service is a separate, smaller job in which the case is disassembled and cleaned, the movement is checked and damaged components are replaced. That service carries a warranty limited to the replaced components, which tells you how narrow its scope is.

One practical detail from AP's price list: the published prices apply to mechanical watches made within the last 25 years and quartz watches made within the last 15. Older watches, including early Royal Oaks from the 1970s to 1990s, are quoted individually, and parts availability can shape the answer.

AP's published Royal Oak overhaul prices are in Swiss francs, exclude taxes and are listed for its Geneva boutique. Quartz is CHF 600, selfwinding CHF 950, extra-thin CHF 1,300, chronograph CHF 1,700, and the QP group (chronograph, perpetual calendar and equation of time) CHF 2,200. The page doesn't show an effective date, so confirm against the current list before you plan around it.

That means a standard selfwinding Royal Oak like the 41 mm 15500ST sits at the lower end, while the extra-thin models, the chronographs and the complicated references cost progressively more. The same price list shows the water-resistance partial service at CHF 450 for standard watches and CHF 900 for complicated ones.

Authorised independent repairers and resellers can set their own prices, so a quote from outside the brand can differ in either direction. Ask what's in the quote before comparing totals.

This is where owners lose value. The Royal Oak's look depends on contrast: brushed flat surfaces against polished chamfers, with crisp transitions between them. Each polish removes metal, and a careless one rounds those edges and blurs the transitions.

AP recommends no more than three to five aesthetic refreshings during the life of a watch. That's a useful ceiling, and it's the brand's own number. In practice, it argues for polishing only when damage is visible and bothersome, and for saying so when you hand the watch over.

AP's list prices the polishing and satin finish separately from the overhaul: CHF 450 for case with bracelet and buckle, CHF 300 for case and buckle, and CHF 150 for the buckle alone. Because it's optional, you can decline it at the time of a service. If you're buying pre-owned, look closely at the bevels and the bracelet links before trusting the photos.

Water resistance is a sealing question, not a property the case keeps forever. Gaskets age, crowns get unscrewed and screwed down hundreds of times, and a watch that was fine five years ago may not be today. That's why AP's yearly check includes it, and why the separate water-resistance service exists.

Ratings vary by reference, so read the figure for your own watch in its documentation rather than relying on a general number. If your watch hasn't been pressure tested since you bought it, have that done before any swimming or serious water contact, and don't operate pushers or the crown while wet.

Magnetisation is the other item on AP's checklist. A watch that suddenly gains or loses a lot of time after sitting near a speaker, a phone case clasp or a laptop is often just magnetised, and demagnetising is a quick job for a watchmaker.

For a watch under warranty, or one you want documented for resale, the brand is the obvious route. AP also lets owners of eligible watches extend the International Sales Warranty through an account, which is worth checking when you buy.

An authorised independent repairer is a legitimate alternative, particularly once a watch is out of warranty, as long as they can source genuine parts and will return the old ones if you ask. Whichever route you choose, request an itemised invoice listing the parts replaced, the finishing performed and the timing results. That paper is what a future buyer or appraiser will want to see.
