When Audemars Piguet assigns a watchmaker to assemble a Jules Audemars Grande Complication, they commit to six to eight months of continuous work on a single piece, completing the entire assembly from first component to final adjustment. Only a handful of watchmakers at the Le Brassus workshops are qualified for this task, with AP producing roughly eight Grande Complication pieces annually across all collections. Single-watchmaker assembly has been a hallmark of the line since its launch.
The 1996 Launch
The 1996 launch of the Jules Audemars Grande Complication took place during a cautious period in Swiss watchmaking. The quartz crisis had subsided, but the industry remained conservative. Most manufacturers were playing it safe, yet Audemars Piguet chose to revive three classical complications in a wristwatch format. The decision traced back to the maison’s earliest days—since the company’s founding in 1875, Jules Louis Audemars pursued intricate movements, producing the first Grande Complication pocket watches by 1882. By 1892, they had developed a minute-repeating movement compact enough for wristwatch dimensions, decades before wristwatches became standard wear.
Between the 1880s and 1890s, Audemars Piguet produced 1,625 watches, with over 300 featuring a split-second function—evidence of the maison’s early mastery of complicated mechanisms. Although this expertise survived the quartz years, production of grande complications had largely halted. The 1996 Jules Audemars Grande Complication reintroduced three classical complications—minute repeater, split-seconds chronograph, and perpetual calendar—this time in a wristwatch format.
Engineering the Calibre 2885
The Calibre 2885 that powers these pieces was developed with help from Renaud & Papi, the same specialists who would later develop complex complications for other manufacturers. The movement contains approximately 648 components fitted within an 8.5mm case profile—more than double the 300 to 350 parts found in standard automatic chronographs. Operating at 19,800 vibrations per hour with 52 jewels, it delivers approximately 45–50 hours of power reserve while managing the three major complications simultaneously.
The Three Complications
The minute repeater represents the most complex of the three. When activated via a case-mounted slide, tiny hammers strike gongs tuned to specific pitches—a low tone for hours, a double “ding-dong” for quarter-hours, and a high tone for minutes past the last quarter. The complication originated in the 1670s when Edward Barlow invented the rack-and-snail mechanism, designed to tell time before electric lighting existed. Case material significantly influences acoustic properties: platinum produces crisp chimes due to its dampening effect, while rose gold delivers warmer tones through greater resonance. Each Jules Audemars Grande Complication’s gongs are individually tuned by hand, a process that relies on the watchmaker’s trained ear and repeated adjustment to achieve precise tonal balance.
The split-seconds chronograph adds another layer of complexity through its rattrapante mechanism. Two chronograph hands sit superimposed—one can be stopped independently while the other continues running, allowing simultaneous timing of two events. The pusher at 2 o’clock controls the split function, halting one hand while the other continues—ideal for timing laps or comparing performance.
The perpetual calendar manages irregular month lengths and leap years automatically, requiring manual correction only in 2100. Cams must be shaped to recognise 28, 29, 30, and 31-day months, account for leap years, and coordinate all this information across multiple display wheels.
Through the sapphire caseback, the three complications share a single, integrated architecture. The gongs position themselves around the movement’s outer edge to optimise acoustic performance. Above them sit the hammers, connected to levers that lift and release in precise sequence. Column wheels—stacked, toothed components—govern the chronograph functions, coordinating start, stop, and reset operations. Hand-finishing extends throughout, including components hidden during wear: bridge edges chamfered to exact 45-degree angles, base plates decorated with overlapping perlage.
Key References
Reference 25866: The Foundation
The ref. 25866 series established what a Jules Audemars Grande Complication should be. Produced in platinum, rose gold, and yellow gold at 42mm diameter and 14mm thickness, it incorporated all three major complications in a classically proportioned case.
The platinum 25866PT weighs over 200 grams, delivering substantial wrist presence.
Rose gold editions like 25866OR offer comparable weight with warmer metal tones, while yellow gold variants add traditional lustre.
Dials featured Breguet numerals on silver-toned backgrounds, with moonphase displays positioned at 12 o’clock. The repeater slide sat at the case edge, ready to activate the chiming mechanism. A pusher at 2 o’clock controlled the rattrapante function. Function and finishing received equal attention, with no compromises made for either.
Reference 25984: Refined Complexity
The ref. 25984OR focused on perpetual calendar and minute repeater, eliminating the split-seconds chronograph. This allowed reduced case thickness while maintaining the two most complex functions. Skeletonised versions exposed the movement through the dial, with day, date, and month sub-dials arranged symmetrically. The openwork revealed polished levers, ruby jewels, and engraved details normally concealed.
Reference 25996PT: Transparency as Statement
The ref. 25996PT combined platinum construction with a transparent sapphire dial, offering simultaneous front and rear movement views.
References 26050OR and 26070PT: Adding the Tourbillon
The rose gold 26050OR and platinum 26070PT incorporated tourbillons, with the rotating cage visible at 6 o’clock. Both measured approximately 42mm, fitted with alligator leather straps. The platinum 26070PT attracted particular collector interest.
Market Analysis
Jules Audemars Grande Complications appear rarely on the secondary market. Technical complexity and proven scarcity drive demand. Auction activity concentrates at Christie’s and Sotheby’s.
A platinum ref. 25866PT from approximately 2004 achieved HKD 1,764,000 (roughly £140,000 / $175,000) at Christie’s in 2022, exceeding its upper estimate of HKD 1,600,000 (roughly £127,000 / $160,000). Current secondary pricing typically begins above £150,000 ($188,000), reaching beyond £400,000 ($500,000) for variants with sapphire dials and complete documentation including original boxes, papers, and service records. The ref. 25996PT with its transparent sapphire dial commands particular premium due to manufacturing complexity and visual appeal. References incorporating tourbillons—the 26050OR and 26070PT—appear even more rarely, with the platinum 26070PT achieving prices approaching £500,000 ($625,000) when complete examples surface.
Asian and European collectors show increasing interest, though ownership involves specific considerations. Authentication requires expert evaluation, and servicing requires authorised specialists. Annual costs can reach several thousand pounds, and certain replacement components must be manufactured individually to match original specifications.
Acquisition depends on authorised dealer relationships and waiting periods are measured in years. With approximately eight pieces produced annually, buyers require both capital and patience.
Enduring Appeal
The Jules Audemars Grande Complication represents Audemars Piguet’s approach to classical watchmaking without compromise. Six to eight months of work by a single watchmaker creates consistency that assembly-line production cannot match. Production remains at eight pieces annually, a figure determined by the time required to assemble each watch to specification rather than strategic scarcity. The combination of restricted output and single-watchmaker assembly ensures these references maintain their position within the secondary market.
