Audemars Piguet Code 11.59 Selfwinding Chronograph Blue Ceramic — Tuscany Blue Grained Dial | Ref. 26439NB.OO.A346KB.01

Audemars Piguet's decision to produce the Code 11.59 Selfwinding Chronograph in blue ceramic for 2025 is a statement of technical confidence matched by very few Manufactures. The 41 mm case — hewn from a material that resists scratches, shrugs off temperature variation, and develops no patina — is paired with a Tuscany Blue grained dial whose textured surface evokes sun-warmed terracotta reinterpreted through a cool chromatic lens. The blue inner bezel frames azured blue chronograph counters set against baguette-cut diamond hour-markers, a combination of precision lapidary and haute horlogerie that the Code 11.59 alone can carry without contradiction.

At the heart of the watch is Calibre 4409, Audemars Piguet's latest-generation in-house selfwinding flyback chronograph movement. Comprising 349 components across a movement diameter of 32 mm and a thickness of 6.8 mm, the calibre operates at 28,800 vph (4 Hz) and delivers a generous 70-hour power reserve across its 40 jewels. The flyback function enables immediate chronograph reset and restart with a single depression of the pusher — a complication that originated in aviation timing and retains all its technical drama in this context.

The blue textured rubber strap, matched in tone to the ceramic case, fastens with an 18-carat white gold pin buckle whose construction quality mirrors the movement's attention to detail. White gold luminescent hands, produced in-house, ensure legibility under all light conditions. Water-resistant to 30 metres, certified with a two-year warranty, and presented complete with box and papers, reference 26439NB is a landmark Code 11.59 — the most technically ambitious expression of the line yet made available.
