Audemars Piguet Stainless Steel
Steel is where the Royal Oak began. Gérald Genta’s 1972 reference 5402 asked buyers to pay gold-watch money for a steel sports watch, and that gamble has defined Audemars Piguet ever since. Our stainless steel inventory runs from the 41 mm 15500 and 15510 Selfwinding models through the 26240 and 26331 chronographs to the 39 mm 16202 “Jumbo” Extra-Thin, the 37 mm 15450 and 15550 references, and rarities such as the 26730 Flying Tourbillon.Browse and filter this collection

Choosing a Stainless Steel Audemars Piguet
Nearly every steel AP on the market is a Royal Oak, so the real decision is case size, complication and generation. The table below maps the reference families currently in our inventory.| Reference | Case | What it is |
|---|---|---|
| 15400 · 15500 · 15510 | 41 mm | Three generations of the core Selfwinding Royal Oak. The 15400 ran 2012–2016, the 15500 added calibre 4302 in 2016, and the 15510 arrived for the 50th anniversary in 2022 with calibre 7121 and a revised bracelet taper. |
| 16202 · 16204 | 39 mm | The “Jumbo” Extra-Thin, successor to the 15202 and the closest thing to Genta’s original 5402 proportions. The 16204 adds an openworked dial. |
| 15450 · 15550 · 15551 | 37 mm | The mid-size Selfwinding Royal Oak. The 15550 and 15551 are the 50th-anniversary replacements for the 15450, sharing the 41 mm models’ calibre 7121. |
| 26240 · 26331 · 26315 · 26320 | 38–41 mm | Royal Oak Chronograph. The 26331 carried the line from 2017, and the 26240 replaced it in 2023 with an integrated flyback movement. |
| 26660 · 26730 | 37–41 mm | Flying Tourbillon — the top of the steel range, and the reason this collection reaches six figures. |
| 26574 | 41 mm | Perpetual Calendar in steel, with moon phase and week-of-year display. |
Audemars Piguet Stainless Steel Price
At Watch My Diamonds, stainless steel Audemars Piguet watches range from $19,999 to $315,800 across 33 priced listings.
Steel sits at the bottom of Audemars Piguet’s retail price list and near the top of the secondary market. A steel 16202 “Jumbo” routinely trades well above its gold siblings, because allocation — not the metal — sets the price. Entry to the collection is a 41 mm chronograph or an earlier 15400; the ceiling is the Flying Tourbillon.
