Audemars Piguet Royal Oak Offshore buying guide: references, sizes and prices

The Audemars Piguet Royal Oak Offshore is the larger, heavier, more openly sporting version of the Royal Oak that the manufacture introduced in 1993 with the 42 mm chronograph 25721ST, a watch so far outside the norms of the day that it was nicknamed "The Beast". Thirty-three years on, the Offshore runs from a 37 mm chronograph to 44 mm tourbillons and grande complications, in steel, titanium, gold, ceramic and forged carbon, and it is the collection where a first-time Audemars Piguet buyer can usually get a watch without joining a waiting list. This guide sets out the current and recent Offshore references by size, explains how they differ from the Royal Oak, gives hedged retail bands and what our sourced catalogue asked for representative references on 21 September 2026, and lists what to check before buying. Bizak & Co. sources the Offshore to order; the Royal Oak Offshore collection lists the configurations we can seek.

What is the difference between the Royal Oak and the Royal Oak Offshore?

Both share the octagonal bezel with eight hexagonal screws, the Tapisserie dial and the integrated bracelet or strap. The Offshore is bigger in every direction: a thicker case with a visible rubber gasket between bezel and case, rubber-clad crown and pushers, a "Méga Tapisserie" dial pattern with larger squares, and cases from 42 to 44 mm on the men's chronographs against 39 to 41 mm for the Royal Oak. The Offshore is water resistant to 100 m on most models and 300 m on the Diver, against 50 m for the Royal Oak. On the wrist the difference is obvious: a 43 mm Offshore chronograph is a heavy, high-profile watch that reads as a sports instrument; a Royal Oak Selfwinding is a slim watch that reads as a design object. Prices differ too, and in the Offshore's favour for the buyer: the manufacture makes the Offshore in larger numbers relative to demand, so steel Offshores trade near their list price while steel Royal Oaks trade well above it, as our Royal Oak price guide shows.

Royal Oak Offshore references by size

The Audemars Piguet watch collection page lists the current Offshore line with the manufacture's specifications, and Audemars Piguet services covers servicing, strap replacement and the extract of archives for older references.

How much is a Royal Oak Offshore at retail?

Audemars Piguet publishes list prices and revises them roughly once a year; the bands here are orientation for 2025 to 2026, and the current figure comes from a boutique. The Diver in steel has sat in the mid US$20,000s. The 43 mm Selfwinding Chronograph 26420 in steel has sat in the low-to-mid US$30,000s, with titanium a little below and ceramic-bezel versions a little above; the 37 mm chronograph in steel with a diamond bezel in the high US$20,000s to low US$30,000s. Gold chronographs run from the US$50,000s on a strap to well over US$100,000 on a bracelet, and the tourbillons and grande complications are individually priced from the low US$200,000s to over US$800,000. Unlike the steel Royal Oak, most of these can be ordered by a new client and delivered within months rather than years, which is the Offshore's practical advantage.

Which Royal Oak Offshore should you buy?

• For a daily chronograph. The 43 mm 26420 in steel is the current reference, with the in-house flyback calibre 4401, 70 hours of reserve and a quick-change strap system; the black dial is the value choice and the blue the most requested.
• For a smaller wrist. The 37 mm 26231 is the same design at a size that suits wrists under 17 cm, and the steel versions with a diamond bezel asked US$34,410 to 37,981 on our catalogue; the 42 mm Diver is the other slim-wrist route.
• For the lowest price. A pre-owned 15710ST Diver, the forged carbon Bumblebee or the 42 mm 26703ST, all under US$26,000 on 21 September 2026.
• For the original look. A pre-owned 44 mm 26400 is the Offshore most people picture from the 2010s, and the steel versions ask in the US$50,000s and up.
• For a collector's piece. The limited editions and the tourbillon chronographs, priced individually and worth a specialist's opinion before you commit.

How does the Offshore wear?

Heavily and visibly. A 43 mm steel chronograph on a rubber strap weighs considerably more than a Royal Oak Selfwinding on a bracelet, and the thick case sits high on the wrist; on a steel bracelet it is heavier still. The 26420's interchangeable strap system, which swaps between rubber and leather without tools, is the feature most owners use most. The Diver is the most wearable Offshore, slimmer than the chronographs with a screw-down crown and an internal bezel operated by the second crown at 10. The 37 mm chronograph wears like a compact sports watch and is the choice for anyone who found the 42 and 44 mm versions too much. Titanium versions of the 43 mm chronograph cut the weight noticeably and are the ones to try if the steel watch felt like a burden.

Is the Royal Oak Offshore a good investment?

Standard steel Offshores trade near retail, which makes them a good watch to buy and a poor one to speculate on: there is little premium to gain or lose, and a watch bought at list and worn for five years will typically sell back at a moderate discount. Limited editions, early references such as the 25721ST and the complicated pieces behave differently and can appreciate, but only with the box, papers and, for the limited runs, the numbered certificate. If resale matters, buy the reference with the strongest following in its size, keep the full set and ask for a written cash-buy assessment before you commit; our sell your watch page explains how we buy.

Buying a Royal Oak Offshore: what to check

• Reference and generation. The 43 mm 26420 and 44 mm 26400 look alike in photographs. The 26420 has the flyback calibre 4401 and a quick-change strap; the 26400 has the modular calibre and a fixed strap fitting. The warranty card and caseback settle it.
• Bezel screws and gasket. The eight screws should align and show clean slots; the rubber gasket between bezel and case should be intact and unfaded.
• Rubber parts. The crown and pusher cladding and the rubber strap harden and crack with age; original replacements come from the manufacture at a cost, and aftermarket straps reduce the offer at resale.
• Case finish. Brushed flats and polished bevels should meet at a sharp line; the Offshore's large surfaces show polishing more than the Royal Oak's.
• Chronograph function. Start, stop and reset should be crisp; on the 26420 the flyback should restart from zero while running. Hands should return exactly to zero.
• Diver bezel and crowns. On the Diver, the internal bezel should turn smoothly from the crown at 10 and both crowns should screw down cleanly.
• Set and edition. Box, card, spare strap and, for limited editions, the numbered certificate; a limited edition without its certificate is priced as a standard watch.

Our authentication process describes what we inspect before dispatch, and our Royal Oak authentication guide covers the case, dial and bracelet details that apply to both collections.
