The Audemars Piguet Royal Oak Offshore is the Royal Oak’s larger, more assertive sport-oriented relative. Introduced in 1993 as reference 25721, it paired a 42 mm case and prominent rubber gasket with a selfwinding chronograph—proportions that challenged the conventions of the time. The Offshore has since grown into a varied collection, so the original watch is useful history, not a specification sheet for every model sold today.
What is the Royal Oak Offshore?
The Offshore is a distinct Audemars Piguet collection built around a bolder interpretation of the Royal Oak’s sporty design. Its defining early statement was scale: at 42 mm across and 14.05 mm thick, the 1993 original was substantially larger than the roughly 36 mm average men’s watch diameter cited by the brand’s Heritage account for that period. The visible gasket, set between the bezel and case, made the departure especially conspicuous.
The Musée Atelier Audemars Piguet describes the 1993 watch as a convention-defying design that helped establish a trend for oversized watches. That response was not uniformly favorable at first; the proportions and visible gasket made the watch a challenging proposition for contemporary tastes.
When did it launch, and who designed it?
The first Royal Oak Offshore, reference 25721, launched at the Basel Fair in April 1993. Audemars Piguet Heritage attributes its design to development work by Emmanuel Gueit. In a retrospective statement reproduced by Heritage, Gueit wrote that, unlike its predecessor, the Offshore “was not a response to any particular request or expectation expressed by any particular market.” Heritage says he wrote this for the Royal Oak anniversary book published in 2012.

How the collection expanded
In 1996, Audemars Piguet expanded the line with 30 mm and 38 mm models and leather-strap variants. Subsequent versions introduced rubber straps, limited editions, additional materials, and more complications. Across its history, the family has included chronographs, calendars, time-zone displays, divers, and high complications; which models are available depends on the period and market.

Heritage records 10,896 deliveries of reference 25721 from 1993 through 2016. That figure applies to the reference alone, not the entire Royal Oak Offshore collection. The same record documents material variations including steel and titanium.
How current Offshore models differ
Official product pages show why it is important to compare exact references. A current 42 mm steel chronograph and a 44 mm ceramic chronograph may both be Royal Oak Offshores, but their sizes, materials, straps, and specified movement details are not interchangeable.

| Detail | Reference 26238ST.OO.2000ST.01 | Described 44 mm ceramic chronographs |
|---|---|---|
| Case size | 42 mm; 15.3 mm thick | 44 mm for the blue- and green-dial examples |
| Case and exterior | Stainless steel, with sapphire crystal and caseback | Black ceramic case; blue and green examples have matching ceramic bezels, pushpieces, and screw-locked crowns, plus titanium pushpiece guards. The grey-dial version has an 18-carat pink-gold bezel and guards. |
| Movement and complication | Selfwinding flyback chronograph; calibre not stated on the cited product page | Selfwinding chronograph, calibre 3126/3840, 365 components, and at least 50 hours of autonomy |
| Water resistance | 100 m | Not stated on the cited collection page |
| Dial and strap | Blue Petite Tapisserie dial; steel bracelet and interchangeable strap system | Smoked blue, green, or grey dial; textured rubber strap |
The 44 mm movement and autonomy specifications apply to the ceramic examples described on the collection page; they should not be attributed to reference 26238ST. For reference 26238ST.OO.2000ST.01, Audemars Piguet’s US product page provides the detailed specifications above. Its search listing showed $51,400, but the opened page did not render price data; treat that figure as a search-result snapshot, not a dependable current quote, and confirm any live price with the brand.
Royal Oak vs. Royal Oak Offshore: what should you compare?
The Offshore’s history establishes its larger, more emphatic original design, but a useful comparison is model-to-model rather than collection name to collection name. Check the specifications for the exact references you are considering:

- Case dimensions: Compare diameter and thickness. A nominally larger diameter does not tell the whole story about how a watch wears.
- Materials: Check the case, bezel, pushpieces, and guards individually; versions within the Offshore line use different combinations.
- Movement and functions: Verify the calibre and whether the watch is a chronograph, flyback chronograph, or another complication.
- Water resistance: Use the figure given for that reference rather than assuming the original’s 100 m applies to the collection.
- Dial and legibility: Note the dial layout and finish, as well as the functions you need to read at a glance.
- Bracelet or strap: Confirm what comes with the exact watch and whether its stated strap-interchange system applies to that reference. Do not assume a third-party strap is compatible based on the collection name alone.
Which Royal Oak Offshore should you compare?
Start with the watch’s exact reference number, then compare its dimensions, materials, movement, water resistance, dial, and included bracelet or strap. Reference 26238ST.OO.2000ST.01 is one official current example for readers interested in a 42 mm steel flyback chronograph with a bracelet and interchangeable strap system. The 44 mm ceramic chronographs offer a different material and strap configuration. Neither example represents every Offshore, and availability can vary by market and change over time.
