Royal Oak Flying Tourbillon

Audemars Piguet Royal Oak Flying Tourbillon 26730ST

The Audemars Piguet Royal Oak Selfwinding Flying Tourbillon Ref. 26730ST.OO.1320ST.01 sits at the intersection of iconic design and haute horlogerie, elevating the classic Royal Oak into a true collector’s piece.

The watch features a 41 mm stainless steel case with the unmistakable octagonal bezel secured by eight hexagonal screws, maintaining the DNA introduced in 1972. The finishing—alternating satin brushing and polished bevels—is executed at an extremely high level, reinforcing the Royal Oak’s reputation for case craftsmanship.

The dial is a smoked blue “Grande Tapisserie”, offering depth and gradient tonality, with the flying tourbillon positioned at 6 o’clock as the visual centerpiece. The layout is intentionally minimal—hours and minutes only—allowing the complication to dominate without distraction.
