Audemars Piguet Royal Oak Price Guide: What Every Reference Costs in 2026

More than fifty years after Gerald Genta sketched an octagonal bezel overnight for the 1972 Basel fair, the Royal Oak remains the watch that defines luxury steel. The family has since grown into divers, chronographs, ceramics, quartz dress pieces, and frosted gold miniatures, and the price spread between them is wider than most buyers expect. This guide covers ten references across that spectrum with realistic 2026 secondary-market figures. The short version: entry starts near US$ 20,800, the anniversary Jumbo closes the list near US$ 97,500, and the sweet spots sit in between.

At a Glance

• Cheapest way in: the Offshore Diver 15710ST around US$ 20,800
• The modern core 41mm: 15510ST at roughly US$ 51,600
• The sweet-spot size: the 37mm 15550ST near US$ 53,200
• All-ceramic option: the 34mm 77350CE at about US$ 61,500
• Anniversary flagship: the Jumbo Extra-Thin 16202ST near US$ 97,500

Full Comparison

1. Royal Oak Offshore Diver 15710ST

The most affordable octagon

It surprises many buyers that the least expensive door into Royal Oak ownership is a dive watch. The 15710ST wraps caliber 3120 in a 42mm case rated to 300 meters, with an internal rotating bezel driven by a second crown at 10 o'clock. Production ended in 2021, and the funkier dial colors from the final years now trade at small premiums over the classic blue.

At roughly US$ 20,800, this is thousands below any time-only steel Royal Oak. The trade-off is size and thickness, at 14.1mm it wears like the sports instrument it is, not like a Genta dress piece.

2. Royal Oak Quartz 67650ST

The thinnest steel case in the family

At just 7.0mm tall, the 33mm quartz 67650ST is flatter than any mechanical steel Royal Oak in the catalog, including the Jumbo. Caliber 2713 keeps it running for years between battery changes, and the case and bracelet receive exactly the same brushed-and-polished finishing as the flagship references. The market prices it around US$ 34,200, which says something about how little the movement type matters when the design is the product.

3. Royal Oak Offshore Chronograph 26420SO

Ceramic at the contact points

The 26420SO puts black ceramic exactly where fingers land, on the bezel, the crown, and the pushers, over a 43mm steel case. Inside runs the in-house caliber 4401 flyback chronograph, and the interchangeable strap system means the rubber can be swapped in seconds without tools. Around US$ 36,800 buys one in 2026, a fair figure for a modern in-house chronograph with this much presence.

4. Royal Oak 15400ST

The discontinued 41 that reset the proportions

Released for the model's 40th anniversary year, the 15400ST pushed the standard Royal Oak to 41mm while holding the profile to 9.8mm, and its dial layout deliberately looked back to the 1972 original. Production ran from 2012 to 2019. As a discontinued reference with the well-proven caliber 3120, it trades near US$ 38,500, noticeably under the current 15510ST, which makes it the value pick among the 41mm generation.

5. Royal Oak 15510ST

The current 41, dated by its rotor

The 15510ST carries caliber 4302 and, in a quirk collectors track closely, its rotor identifies the production window, since early examples wear the 50th anniversary rotor and later ones a standard weight. Expect around US$ 51,600 on the secondary market. Blue remains the reference configuration, though the newer sand-gold dial has been closing the gap in demand.

6. Royal Oak 37 15550ST

Where 41mm stops being automatic

Introduced in 2022, the 37mm 15550ST has become the quiet consensus pick for buyers who find 41mm slabby and the Jumbo unobtainable. Caliber 5900 keeps the case wearable, and details like the gold-toned wordmark elevate the dial. It actually trades slightly above the 41mm at about US$ 53,200, evidence that the market has stopped treating mid-sizes as a discount category.

7. Royal Oak Chronograph 26240ST

The first fully in-house Royal Oak chronograph

For a quarter century the Royal Oak chronograph ran on outside base movements. The 26240ST ended that in 2022 with caliber 4401, a column-wheel flyback with a vertical clutch, housed in a 12.4mm case. The 50th-anniversary blue with matching counters is the configuration to chase. Budget roughly US$ 59,300, and note that stainless chronographs have historically been among the most liquid Royal Oaks when it comes time to sell.

8. Royal Oak 34 Ceramic 77350CE

Finished with diamond tools

Black ceramic is so hard that the 77350CE's satin surfaces and polished bevels have to be cut with diamond-tipped tooling, and the finishing takes several times longer than steel. Pink gold bezel screws and a titanium caseback offset the monochrome. The 34mm sizing has broadened its audience well beyond the women's line it launched in, and the market now sits near US$ 61,500.

9. Royal Oak Mini Frosted Gold 67630OR

Sparkle without a single stone

The frosted finish, developed with jeweler Carolina Bucci in 2016, hammers the gold surface into thousands of microscopic facets that glitter like pave without any diamonds. On the 23mm Mini in pink gold, running quartz caliber 2730, the effect is jewelry first and watch second. It commands about US$ 92,400, and supply is thin because production volumes are genuinely small.

10. Royal Oak Jumbo Extra-Thin 16202ST

The 1972 recipe, current production

The 16202ST is the direct descendant of the original 5402, with the same 39mm by 8.1mm proportions and a Bleu Nuit Nuage 50 dial mixed to the historical formula. Caliber 7121 replaced the long-serving 2121 in 2022 and finally added a quick-set date. First-year examples with the anniversary rotor carry the strongest premiums. At around US$ 97,500 it is the most expensive steel watch in this guide, and the one whose price needs the least explaining.

Final Thoughts

Pick the family before the reference. If you want the pure Genta silhouette, the decision is between the discontinued 15400ST for value, the 15510ST or 15550ST for current production, and the 16202ST if budget allows. If you want complications, the in-house 26240ST is the strongest chronograph the line has ever fielded. And across every reference, condition rules the pre-owned market, since the Royal Oak's broad brushed surfaces show polishing mistakes more cruelly than almost any other case design.
