Audemars Piguet Royal Oak Concept Tourbillon Chronograph Titanium — Skeleton Openworked Dial | Ref. 26587TI.OO.D067CA.01

Representing the most technically ambitious territory in the entire Audemars Piguet catalogue, the Royal Oak Concept Tourbillon Chronograph Openworked Selfwinding 26587TI is a watch that exists beyond conventional horological categories. The 44 mm titanium case — lightweight, corrosion-resistant, and brutally technical — houses the combination of a flying tourbillon and a column-wheel chronograph within a fully openworked architecture, the skeleton dial dissolving any boundary between observer and mechanism. A titanium bezel and screw-locked crown frame the display, while a rubber strap with tang buckle positions the watch unambiguously in the realm of high-performance sport.

The selfwinding movement powering the 26587TI combines complications that individually represent manufacture peaks: the flying tourbillon rotates in free suspension, compensating for gravitational deviation with elegant mechanical ingenuity, while the integrated chronograph delivers split-second timing capability. The openworked architecture that Audemars Piguet's master craftsmen have applied to every visible surface transforms the watch into a three-dimensional mechanical composition, its bridges and plates hand-decorated to a standard that rewards magnification. The black and red tonal scheme of the movement adds a contemporary edge to the classical complications within.

Royal Oak Concept Tourbillon Chronographs are among the most complex and limited pieces Audemars Piguet produces, and examples complete with box and papers command immediate attention when they surface. The openworked selfwinding configuration — marrying automatic convenience with complete visual transparency — is a configuration that satisfies both the pragmatic wearer and the dedicated horological scholar. At HKD 339,999, this is a benchmark acquisition for the serious Concept collector.
