Audemars Piguet Royal Oak Tourbillon Chronograph Platinum — Blue Openworked Dial | Ref. 26347PT.OO.D315CR.01

Platinum, a tourbillon, and a hand-wound chronograph: the 26347PT.OO.D315CR.01 assembles the most prestigious materials and complications the Royal Oak canon offers into a single statement of horological supremacy. The 950 platinum case — 44 mm in diameter, 13.2 mm thick — achieves a cool, almost ethereal gravitas that only this rarest of precious metals can bestow, while the satin-brushed blue openworked dial transforms the traditional Royal Oak architecture into a window onto pure mechanical art.

Calibre 2936, the movement within, is hand-wound and combines a flying tourbillon at 6 o'clock with a column-wheel chronograph of the highest horological refinement, delivering approximately 72 hours of power reserve. Every component of the skeleton dial is finished to exhibition standard: satin-brushed bridges in a blue that echoes the dial, pink gold applied hour-markers, and Royal Oak hands with luminescent coating provide orientation across the open architecture. Blue counters and the inner bezel maintain the monochromatic composition with deliberate elegance.

A glareproofed sapphire caseback exposes the full movement display, complemented by a 950 platinum AP folding buckle securing the hand-stitched large square scale blue alligator strap. Water-resistant to 20 metres, Ref. 26347PT is positioned squarely for the connoisseur collector — a watch of extraordinary rarity, technical complexity, and aesthetic resolution that exemplifies what Audemars Piguet's manufacture is uniquely capable of producing.
