Audemars Piguet Royal Oak Steel — Blue Petite Tapisserie Dial, 50th Anniversary | Ref. 26670ST.OO.1240ST.01

Launched as part of Audemars Piguet's landmark 50th Anniversary programme in 2022, the 26670ST.OO.1240ST.01 reintroduces the Royal Oak's most revered proportion — the 39 mm Jumbo format — dressed in stainless steel with a serene blue Petite Tapisserie dial. This is a watch conceived for those who understand that restraint, in horology, is the most powerful form of expression, recalling the elegance of the original 5402 while speaking entirely to the present moment.

The movement powering this reference is Calibre 2121 — the ultra-thin automatic calibre that has defined the Jumbo Royal Oak since 1972. Measuring a mere 3.05 mm in height and beating at 2.75 Hz with 40 hours of power reserve, Cal. 2121 is one of the most celebrated movements in horological history, its architecture engineered for the Jumbo's slim 8.1 mm case profile. The dial's Petite Tapisserie texture — finer and more delicate than its Grande counterpart — is rendered in a blue that shifts from cerulean to midnight depending on available light, complemented by luminous hands and steel applied hour-markers.

The 39 mm octagonal case and fully integrated stainless steel bracelet reference the purist's ideal of the Royal Oak in its most classical expression. The screw-down crown, transparent caseback, and AP folding clasp complete a package that comes box and papers fresh, priced as a unisex statement of horological authority. Ref. 26670ST is destined for the rarified company of watches that define their era.
