Audemars Piguet Royal Oak Concept Titanium — Skeleton Openworked Dial | Ref. 26650TI.OO.D013CA.01

The Royal Oak Concept series represents Audemars Piguet's most radical departure from convention — a laboratory for complication architecture that Genta's original 1972 brief could scarcely have imagined. The 26650TI is the 2023 generation's most dramatic statement: a 43 mm titanium case that encloses a fully skeletonised movement, exposing every layer of mechanical complexity through an openworked dial that renders the watch a wearable engine.

The case in grade 5 titanium — valued for its exceptional strength-to-weight ratio and hypoallergenic properties — is anchored by an octagonal bezel referencing the Royal Oak lineage, while black ceramic pushpieces and a screw-locked crown introduce a contrasting technical aesthetic. Water resistance to 50 metres speaks to the structural precision of the case construction. The sapphire crystal caseback mirrors the transparency of the dial, offering a dual perspective on the movement that inhabits the space between them. Luminous hands and markers ensure the openworked composition remains legible across all conditions.

Valued at $199,999, the 26650TI commands a position at the apex of the Royal Oak Concept hierarchy. Its split-second chronograph, GMT, and large date complications — executed entirely within a skeletonised architecture — represent some of the most technically demanding watchmaking in contemporary haute horlogerie. Complete with box and papers from the 2023 release, this is an acquisition for the serious collector who understands that the Concept series occupies a category unto itself: part timepiece, part mechanical sculpture, entirely irreplaceable.
