The Audemars Piguet Royal Oak Offshore Diver 15720 is the current-generation dive-rated Offshore, a 42 mm three-hand watch with a rotating dive bezel, 300 m water resistance and a rubber strap with steel or gold links, positioned as the more genuinely sports-functional counterpart to the larger Offshore chronograph references. This guide covers the 15720's specifications, dial colour options, how it compares with its 15710 predecessor and with the standard Royal Oak Selfwinding, current price context and what to check before buying. Bizak sources the 15720 to order; the Royal Oak Offshore collection lists the configurations we can seek.

What makes the Offshore Diver a genuine dive watch?
Unlike the standard Royal Oak's largely nominal water resistance, the Offshore Diver is rated to 300 m, in line with dedicated dive watches, and carries a unidirectional rotating bezel meant to time a dive rather than simply decorate the case. The screw-down crown and the diver's extension on the strap, which lets the watch fit over a wetsuit, both mark it as built for water use rather than styled to suggest it. It keeps the Royal Oak's octagonal bezel and integrated design language, but every functional element beneath that design serves an actual diving watch's requirements.
15720 versus 15710: what changed?
| 15720 | 15710 (predecessor) | |
|---|---|---|
| Dial pattern | Méga Tapisserie, a bolder, larger-scale version of the classic pattern | Standard Tapisserie pattern |
| Bezel insert | Ceramic on most colourways | Aluminium on most references |
| Case | 42 mm, refined finishing | 42 mm |
| Water resistance | 300 m | 300 m |
The 15720 is the current production reference; the 15710 is the immediately preceding generation, still available on the secondary and pre-owned market and, in many cases, priced more accessibly than the current reference while offering essentially the same functional dive-watch specification.

Offshore Diver versus standard Royal Oak Selfwinding: which to buy?
The Offshore Diver and the standard 41 mm Selfwinding share the Royal Oak's octagonal design language but differ in almost everything else: the Diver is on a rubber strap rather than a bracelet, rated to 300 m rather than the standard model's more modest resistance, and built around an active dive bezel rather than a fixed one. Buyers who want the classic Royal Oak silhouette on a metal bracelet for everyday and more formal wear should choose the Selfwinding; buyers who want a genuinely capable water watch with Royal Oak styling, worn more casually on rubber, should choose the Offshore Diver.
How does the Offshore Diver wear?
At 42 mm it wears close to the standard Royal Oak in diameter but noticeably lighter thanks to the rubber strap, and the case is proportioned with divers in mind rather than slimmed for a formal profile. The dive bezel adds a small amount of extra case height compared with the fixed-bezel Royal Oak, but the rubber strap's flexibility more than offsets that in everyday comfort. It suits a wide range of wrist sizes and reads as a casual, sport-oriented watch rather than the dressier presence of a bracelet Royal Oak.
Which dial colour is most requested?
Blue is generally the most requested Offshore Diver dial, echoing the same preference seen across much of AP's steel sport-watch range, followed by black and then the more distinctive green and grey options that have appeared in recent production. The Méga Tapisserie pattern reads differently across colours: darker dials show the pattern more subtly under most lighting, while the brighter blue and green options make the raised pyramidal structure more visually prominent. Buyers choosing a dial colour purely on resale grounds should lean toward blue or black; buyers choosing for personal preference have a genuinely wide range to pick from without a large price gap between colours at the same reference.
What is the Méga Tapisserie pattern?
Méga Tapisserie is AP's larger-scale version of the classic Tapisserie guilloché pattern used across the Royal Oak family, with more pronounced, chunkier pyramidal facets than the finer pattern on the standard Royal Oak and Royal Oak Chronograph dials. It was developed specifically for the Offshore line's larger cases, where the standard fine Tapisserie pattern would read as visually thin relative to the case size; the bolder pattern suits the Offshore's larger, sportier character. It is one of the clearest visual distinctions between an Offshore dial and a standard Royal Oak dial at a glance, independent of case size alone.
Is the Offshore Diver a good investment?
Treat it as a watch to wear rather than a financial instrument. The steel Offshore Diver has generally held reasonable demand on the secondary market as one of AP's more accessible current references, though less consistently at a premium than the standard steel Selfwinding or the Jumbo Extra-Thin. The discontinued 15710 has developed its own following as the earlier, sometimes better-value route into the same dive-watch concept. A full set with box, papers and, where applicable, any spare strap tends to command a firmer price than a watch-only example. Buy the dial colour you actually want to wear; if resale matters, ask for a written cash-buy assessment before you commit.
Buying a used Offshore Diver: what to check
- Reference and dial match. Confirm the full reference number, including dial colour suffix, against the case back and dial print.
- Bezel action. The unidirectional dive bezel should rotate with firm, even clicks and stop cleanly at each minute marker, without back-play; a loose or sticking bezel suggests wear or damage.
- Rubber strap condition. Original AP rubber straps age and can crack; a replaced strap is not necessarily a problem but should be priced into any negotiation.
- Crown and gaskets. The screw-down crown should thread smoothly; given the 300 m rating, a pressure test is worthwhile before regular water use on an older example.
- Warranty card and serial. The engraved case serial should match any accompanying card; AP does not reissue cards for lost paperwork.
- Movement service history. Ask for the last service date and receipt; AP's service information page outlines what a factory service covers.
- Price against the band. A reference offered well under the ranges above for its dial and condition is the single most reliable warning sign.

Quick answers
What is the Royal Oak Offshore Diver 15720?
The current-generation dive-rated Royal Oak Offshore, a 42 mm steel watch with a rotating bezel, 300 m water resistance and a rubber strap, offered in several Méga Tapisserie dial colours.
How much does a Royal Oak Offshore Diver cost?
Bizak's sourced catalogue listed steel 15720 references between US$29,306 and US$32,960 depending on dial colour, and the predecessor 15710 from US$19,809, all brand new or pre-owned and sourced to order, on 26 September 2026.
What is the difference between the 15720 and the 15710?
The 15720 uses a bolder Méga Tapisserie dial pattern and generally a ceramic bezel insert; the 15710 uses the standard Tapisserie pattern and mostly aluminium inserts. Both share the same 42 mm case and 300 m water resistance.
Is the Offshore Diver rated for actual diving?
Yes. It carries 300 m water resistance, a unidirectional rotating dive bezel and a diver's extension on the strap, all functional features rather than styling references.
Does the Offshore Diver come on a bracelet?
Most examples are sold on a rubber strap with steel or gold links; a full metal bracelet is not the standard configuration for this reference.
