It pairs the Royal Oak’s angular steel case and integrated bracelet with AP’s Calibre 4302, a date display and a stated 70-hour power reserve. Here are the reference-specific details—and the checks that matter when comparing examples.
Where the 15500ST fits in the Royal Oak line
AP’s heritage chronology traces this standard-size selfwinding branch from the 39 mm Royal Oak 15300, equipped with Calibre 3120, to the 41 mm 15400 in 2012, then to the 15500 in 2019. The 15500 continued the 41 mm format and succeeded the 15400. Audemars Piguet’s heritage chronology and a 2019 Phillips auction essay support that lineage.
The 15500ST is not the Royal Oak “Jumbo.” That nickname belongs to the original 39 mm Royal Oak and the related Jumbo lineage, not this standard 41 mm Selfwinding reference. Nor should it be conflated with the later 15510, a distinct reference associated with a subsequent design evolution.
Case, dial and bracelet specifications
For the blue-dial 15500ST.OO.1220ST.01, AP lists a stainless-steel case measuring 41 mm across and 10.5 mm thick, with 50 m stated water resistance. It has a glare-proofed sapphire crystal and caseback, a screw-locked crown, and a matching stainless-steel bracelet secured by an AP folding clasp. These are manufacturer specifications, not an independent water-resistance test. See the official blue-dial product page.

Blue and black dials
AP describes both the blue 15500ST.OO.1220ST.01 and black 15500ST.OO.1220ST.03 with a Grande Tapisserie pattern, white-gold applied hour markers and luminous Royal Oak hands. The black-dial description additionally highlights wider indexes, a minute track printed around the dial’s outer area, and a date window positioned farther from the centre. Compare the exact suffix rather than relying on a listing that says only “15500ST.” AP’s black-dial product page describes those details.
Calibre 4302 and functions
The 15500ST uses AP’s selfwinding Calibre 4302. The movement provides hours, minutes, central seconds and a date display. AP lists 32 jewels, 257 parts, a frequency of 4 Hz (28,800 vibrations per hour), a 70-hour power reserve, a 32 mm total diameter and 4.9 mm thickness on its official blue-dial listing.

Phillips likewise identifies Calibre 4302 and a 70-hour reserve in its catalogue entry, contrasting the reserve with the 60 hours of the predecessor movement. That is a specification comparison, not a claim about observed running time or accuracy in an individual watch.
What to compare when buying a 15500ST
Examples can share the reference family while differing in dial, condition and documentation. Assess the particular watch and the evidence offered with it; a catalogue entry or seller description alone is not a general authentication guarantee.

- Exact reference and dial: Confirm the complete reference suffix and whether the dial is blue, black or another documented variant. Match the photographed dial details to the claimed version.
- Case and bracelet condition: Inspect the edges, brushed and polished surfaces, links, clasp and fit. Look for wear or refinishing that affects the original geometry and finishing.
- Service evidence: Ask for dated service records and clarify what work was performed and by whom. Do not treat a seller’s unsupported “serviced” claim as documentation.
- Completeness and provenance: Check which box, papers, accessories and ownership records are actually included, and whether their details correspond to the watch. Phillips’ lot catalogue is an example of how a specific sale records condition and accessories; its description applies only to that lot.
Prices and resale estimates need dates
WatchCharts listed a $41,749 market estimate for the model as of September 30, 2026, and a $27,800 retail figure dated March 2023. These are third-party figures surfaced by WatchCharts, not current AP offers, guaranteed sale prices or proof of what a particular watch will sell for. The market estimate is an estimate at a stated date, not a realized average sale price. AP’s live product page did not provide a reliably rendered current price, so no current official price is stated here.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Warranty status is specific to the watch
AP’s surfaced warranty text describes two years of coverage against manufacturing defects subject to its International Sales Warranty, with five-year coverage applying to watches purchased through the authorized network from January 1, 2017, subject to that warranty. Because the live page may show account-specific information and coverage depends on the individual watch and terms, verify the watch’s warranty status and current AP conditions directly before relying on a warranty claim.
