Audemars Piguet Code 11.59 Perpetual Calendar 26443NB.OO.D002CR.01 White Gold Black Ceramic Openworked Dial (2026)

描述

Introduced early 2026, reference 26443NB marks pivotal moment for Code 11.59 collection—first openworked perpetual calendar since line’s controversial 2019 debut, elevating the “other watch” to haute horological heights previously reserved for Royal Oak. The watch debuts alongside Royal Oak Perpetual Calendar Openworked (reference 26685XT) as twin vehicles for revolutionary Caliber 7139—openworked evolution of 2025’s groundbreaking Caliber 7138 that transformed perpetual calendar user experience through patented all-in-one crown adjustment system. Where Caliber 5135 represented final iteration of legendary ultra-thin 2120 base (dating to 1967) powering openworked perpetual calendars through 2025’s 150th Anniversary models, Caliber 7139 establishes new architectural foundation for AP’s most emblematic complication. The movement measures just 4.1mm thick despite integrated perpetual calendar mechanism, representing decisive break from nearly six-decade-old platform. From 1955’s world’s first leap-year perpetual calendar wristwatch through 1980s Royal Oak Perpetual Calendar establishing cornerstone status, Audemars Piguet has consistently advanced the genre—Caliber 7139 continues this legacy while addressing modern ergonomic demands.

The 41mm case measures 10.6mm thick, combining 18k white gold for the round bezel and caseback with black ceramic octagonal middle section—signature Code 11.59 construction framing the round outer elements around geometric core. The case architecture features alternating polished and satin-brushed surfaces creating depth through light interplay, while the double-curved sapphire crystal tops the dial with glareproofing on both sides. A sapphire exhibition caseback reveals the openworked Caliber 7139 beneath, secured by five screws and offering unobstructed view of the movement’s mechanical artistry. Water resistance reaches 30 meters, while the black ceramic screw-locked crown at 3 o’clock flanked by slender white gold casebands integrates the revolutionary crown-only adjustment system. The transparent sapphire dial places Caliber 7139 center stage, with lightly smoked transparent subdials hovering above the exposed openworked movement creating three-dimensional layered effect. The perpetual calendar follows traditional layout: day indication at 9 o’clock incorporates 24-hour indicator with red-marked no-correction zone between 9 PM and 3 AM, large instantaneous jumping date aperture commands 12 o’clock, month and leap year share 3 o’clock position, while aventurine moonphase at 6 o’clock adds darker, more mysterious presence compared to typical blue moonphases. Peripheral week indication runs along black inner bezel with printed markings. Applied rhodium-toned 18k pink gold hour markers provide contrast against the openworked backdrop, complemented by 18k white gold hands with red tips filled with luminescent material ensuring legibility. The self-winding Caliber 7139 comprises 423 components with 41 jewels, measuring 29.6mm diameter by 4.1mm thickness despite its complexity, operating at 28,800 vph with 55-hour power reserve. The openworked architecture showcases main plates, bridges, date wheels, leap year wheels, and barrels shaped through electrical discharge machining with all non-essential material removed, while bridges receive hand-finished V-angles requiring over 30 hours painstaking work per movement. Refined decorations include satin brushing, circular graining, snailing, and chamfering creating striking contrasts, while non-magnetic balance springs are fitted to balance wheel by hand using traditional techniques typically reserved for limited-production movements. The openworked pink gold rotor, barrel bridge, and balance wheel bridge create warm contrast against rhodium-plated steel components visible through sapphire caseback. Black alligator leather strap with 18k white gold three-blade folding clasp.
