Audemars Piguet Royal Oak Tourbillon 26730or.oo.1320or.05 Watch

Audemars Piguet Royal Oak Tourbillon Extra-Thin — Ref. 26730OR.OO.1320OR.05

The Royal Oak Tourbillon Extra-Thin in 18-carat rose gold stands as one of the most technically refined expressions of Gerald Genta's iconic 1972 design. Reference 26730OR.OO.1320OR.05 pairs the architectural rigour of the Royal Oak case with the horological mastery of a flying tourbillon — a complication that eliminates the traditional tourbillon bridge, allowing the rotating cage to float freely at 6 o'clock, visible in its entirety against the signature Grande Tapisserie dial.

Case & Dial

The 41 mm case is crafted in 18-carat rose gold, polished and satin-brushed across its alternating surfaces in the manner that has defined the Royal Oak since its inception. The integrated bracelet flows seamlessly from the case, secured by the AP folding clasp. The smoked salmon-toned dial — a hallmark of rose gold Royal Oak references — is executed in the Grande Tapisserie pattern, framed by an applied rose gold hour-marker chapter ring and complemented by blued-steel hands.

Movement

Powering the watch is Calibre 2924, Audemars Piguet's in-house ultra-thin flying tourbillon movement. At just 3.05 mm in height, it represents a significant feat of miniaturisation. The tourbillon cage completes one rotation per minute, compensating for the effects of gravity on the escapement. A power reserve of approximately 70 hours is delivered via a single barrel, wound through the crown at 3 o'clock.

Provenance & Collectability

The Royal Oak Tourbillon occupies the apex of the Royal Oak family — a timepiece that distils over five decades of design heritage into a single, uncompromising statement. Produced in limited numbers, it is sought by collectors who value both the aesthetic authority of the Royal Oak and the mechanical complexity of a hand-finished flying tourbillon. The rose gold configuration of reference 26730OR adds warmth and depth to the already commanding presence of the 41 mm case.
