AMBUSH and Audemars Piguet Drop a 150-Piece Royal Oak Tourbillon

May 27. Audemars Piguet posted the collab overnight: a Royal Oak Concept Flying Tourbillon reworked with AMBUSH, the Tokyo-based studio run by Yoon Ahn and Verbal. Limited to 150 pieces, all numbered, in 38.5 mm titanium with a black aventurine dial.

The aventurine catches light the way only stone can. Not lacquer, not enamel. The dial sits under a sapphire crystal with an anti-reflective treatment, which means the stone reads clean in direct light and shimmer-dark in shade. The flying tourbillon sits at six o'clock, visible through the dial cutout. Movement is the Calibre 2964, hand-wound, 237 parts, 72-hour power reserve.

The case is brushed titanium, not polished. The bezel is the Royal Oak signature octagon with eight exposed screws. The crown is at three o'clock, screw-down, with an engraved AP monogram. Water resistance is 100 meters, which is more than most tourbillons bother with.

AMBUSH's hand is visible in two places: the case-back engraving, which reads "AMBUSH" in the studio's signature all-caps font, and the strap, a rubber composite with a titanium folding clasp. The strap texture is hexagonal, a nod to the octagonal bezel without mirroring it directly.

Yoon Ahn has worked with Dior, Converse, Nike. Verbal co-founded A Bathing Ape before AMBUSH. This is their first watch collab at this tier. Audemars Piguet has done Royal Oak Concepts with Marvel, with Kaws, with various athletes. This one feels quieter. No cartoon dial, no superhero colorway. Just titanium, stone, and a tourbillon that floats.

The piece ships now. Retail sits north of $200,000, which is standard for a Royal Oak Concept with a flying tourbillon and a limited run. The aventurine dial alone adds material cost; aventurine is copper-flecked glass, difficult to cut thin enough for a watch dial without fracturing.

The collab reads as AMBUSH entering the high-complication watch space without loud signaling. The logo is case-back only. The strap is the tell. The rest is Audemars Piguet doing what it does, with AMBUSH adjusting the details where adjustments matter.
