A pre-owned Audemars Piguet Royal Oak Offshore in stainless steel starts at roughly £11,500–£13,000 for an older, well-worn Chronograph without box or papers, and settles around £15,500–£20,000 for a good, recent 42mm example with a full set (asking prices, UK market, July 2026). Rose gold and the earlier “Beast” references sit far higher. This is a watch bought for what it is — an oversized, armoured icon — and it has held its money better than most of the industry’s chunky sports chronographs.

What does a pre-owned Royal Oak Offshore actually cost?
The Offshore is a family, not a single watch, and the price you pay tracks the metal and the reference far more than the age. Steel is the entry; forged carbon and ceramic sit a little above it; rose gold roughly doubles the ticket; and the early references — particularly the 1993 original — carry a collector premium that has nothing to do with condition. The table below segments the market by configuration, because blending a steel Chronograph with a gold one gives a number that describes no real watch.
| Configuration | Reference | Entry / floor (worn, no box & papers) | Typical–premium asking |
|---|---|---|---|
| Steel 42mm Chronograph | 26470ST (earlier 26170ST) | ~£11,500–£13,000 | £15,500–£20,000 |
| Steel 42mm Diver (300m) | 15710ST / 15720ST | ~£13,000–£14,500 | £15,000–£24,000 |
| Steel “Safari” (ivory Méga Tapisserie) | 26470ST.OO.A801CR | ~£12,800 | £15,300–£17,995 |
| Forged carbon + ceramic, 44mm | 26400AU.OO.A002CA | ~£14,966 | £15,000–£19,200 |
| Rose gold Chronograph, 42mm | 26470OR / 26401RO | ~£25,000 | £25,000–£45,000 |
| 25721ST “The Beast” (1993 original) | 25721ST | ~£22,000 | £22,000–£30,000+ |
| “End of Days” (1999, LE 500) | 25770SN | ~£20,700 | £23,000–£36,000 |

Which reference should you start with?
For most buyers the honest answer is the steel 42mm Chronograph, ref 26470ST. It is the reference the market makes the deepest, so it is the easiest to buy well and the easiest to sell on, and its in-house calibre 3126/3840 removed the old worry about the earlier 26170ST’s sourced movement. If you want the tool-watch version, the 300m Diver (15710ST) with its internal rotating bezel is the one enthusiasts reach for; blue and black dials are the value, green and the “Funky Colours” dials cost more.

Why is it called “The Beast”?
Audemars Piguet handed the brief to a 22-year-old designer, Emmanuel Gueit, and asked for a bolder Royal Oak for a younger buyer. The result was the 42mm ref 25721ST — enormous in 1993, when the standard Royal Oak was 39mm — and the trade nicknamed it “The Beast.” It effectively invented the oversized luxury sports watch, a category the rest of the industry then spent two decades copying. Watch lore has it that the supersized case and rubber-clad crown dismayed purists, reportedly including original Royal Oak designer Gérald Genta — and the Offshore went on to become one of AP’s commercial pillars regardless.
What makes an Offshore an Offshore?
Two things. First, the dial: an oversized version of the Royal Oak’s hobnail waffle guilloché, the “Méga Tapisserie,” with applied Arabic numerals and a screw-locked crown flanked by chunky pushers. Second, the celebrity history. The 1999 “End of Days” was AP’s first blacked-out watch, a PVD-coated limited edition of 500 made with Arnold Schwarzenegger, and it opened the door to a run of collaborations — Shaquille O’Neal’s 48mm 26133ST, Michael Schumacher, LeBron James, Jay-Z, more recently Travis Scott — plus themed Safari, Diver and Survivor series. That cultural weight is part of why the model holds its value.

Has the Royal Oak Offshore held its value?
Broadly, yes. The steel Chronograph trades close to, and often above, its original retail once you account for the difficulty of buying one new, and the early references have appreciated as genuine collector pieces — Gueit’s own “Beast” made CHF 102,500 at auction. That is a description of how the watch has behaved, not a forecast: prices for oversized sports chronographs move with fashion, and they can fall. This is not investment advice. Buy the Offshore because you want to wear it; treat its resilience as a bonus, not a plan.
Buying one
Whatever the reference, the checklist is the same: box and papers lift the price and the ease of resale, the case should be unpolished with its factory bevels intact, and the movement should have a recent service history. Chrono6538 sells authenticated Royal Oak Offshore pieces — checked, guaranteed and photographed — at a premium to the bare private-market floor quoted above, which is the trade-off for not gambling on an anonymous listing.
