Audemars Piguet Royal Oak Grande Complication — Openworked Titanium with Minute Repeater, Perpetual Calendar & Split-Seconds | Ref. 26065IS.OO.1105IS.01

Few timepieces in the history of modern watchmaking pack as many complications into a single case as the Royal Oak Grande Complication, and the 26065IS.OO.1105IS.01 represents that tradition at its most technically heroic. Within a 44 mm titanium case — lightweight at 14.80 mm thick, yet structurally rigid enough to house Calibre 2885 — AP's engineers achieved the near-impossible: perpetual calendar displaying day, date, week, moon phase, month, and leap year; a minute repeater striking the hours, quarters, and minutes on demand; and a split-seconds chronograph with small seconds at 9 o'clock. The sapphire caseback and openworked dial dissolve any barrier between wearer and the 500-plus components orchestrating this mechanical symphony.

The dial architecture is theatrical: smoky counters float above the exposed movement's slate grey plate, their recessed surfaces providing legibility contrast against the technical complexity beneath. White gold Royal Oak hands with luminescent coating indicate hours and minutes, while white chronograph seconds, split-seconds, and a contrasting inner bezel with white minute circle complete the display hierarchy. The entire mechanical landscape — spring barrels, escapement, perpetual calendar cam stack, minute repeater hammers and gongs — is rendered visible, a choice that demands flawless finishing of every surface, whether seen or unseen.

The titanium integrated bracelet, closing with AP's folding buckle and water-resistant to 20 metres, grounds this extraordinary complication in the Royal Oak's sporting idiom. Offered at a price that reflects the decade of development Calibre 2885 required, the 26065IS.OO.1105IS.01 is a horological landmark — the kind of watch that rewrites the collector's definition of what a wristwatch can be.
