Audemars Piguet Royal Oak Steel Blue Dial 41mm Tourbillion 26510st

The 26510ST is one of the very few Royal Oak tourbillons crafted in stainless steel, featuring a 39mm case—the same dimensions as the iconic "Jumbo." Paired with a striking blue sunburst dial and visible tourbillon at 6 o’clock, it blends elegance, heritage, and high horology in a highly wearable form.

Extremely rare. Most Royal Oak tourbillons are released in precious metals, making the steel version highly sought-after. Limited in production and hard to find on the secondary market, the 26510ST has become a grail piece for many collectors.

This reference features the Caliber 2924, a hand-wound movement with a beautifully finished flying tourbillon at 6 o’clock. It offers a 70-hour power reserve and is admired for both its aesthetic architecture and mechanical precision.

While the "Jumbo" (like Ref. 15202ST) focuses on ultra-thin simplicity, the 26510ST adds a serious complication—the tourbillon—without compromising the iconic 39mm Royal Oak silhouette. It’s ideal for collectors who love the classic size but want something mechanically elevated.

Due to its limited production, steel case, classic proportions, and presence of a tourbillon, the 26510ST is not only highly collectible but also holds strong potential for value retention or appreciation—especially among those who prize both design and rarity.
