Complications transform mechanical watches into true masterpieces of haute horlogerie. They offer far more than just displaying hours, minutes, and seconds — ranging from simple date displays to astronomical complications and intricate chiming mechanisms such as a grande sonnerie or a perpetual calendar. The more complications a watch combines, the greater the technical challenge, and the more impressive the innovation, watchmaking expertise, and craftsmanship. Complicated watches are not merely timepieces but expressions of precision, luxury, and technical excellence.
The Most Complicated Watches in the World – Masterpieces of Haute Horlogerie
Wristwatches: Complexity in a Wearable Format
Among the most complicated wristwatches in the world, the Patek Philippe Grandmaster Chime Ref. 6300A stands out as an absolute icon. With a total of 20 complications, including five striking mechanisms such as a grande sonnerie and an alarm with a melody sequence, it exemplifies modern watchmaking artistry. Its reversible double dial features classical time indications on one side and complex calendar functions on the other. At auction, it fetched over CHF 31 million — the highest price ever paid for a wristwatch.
Even more complex is the Franck Muller Aeternitas Mega 4, boasting an astounding 36 complications. This exceptional watch features a perpetual calendar valid until the year 9999, multiple time zone complications, a minute repeater, and a carillon striking mechanism. With over 1,400 individual components, it is a technical marvel and one of the most sophisticated wearable luxury watches in the world.
The Jaeger-LeCoultre Hybris Mechanica à Grande Sonnerie, with 26 complications, is considered a masterpiece of watchmaking. It can play the complete Westminster chime on four gongs and combines a tourbillon, perpetual calendar, retrograde displays, and astronomical complications. With more than 1,300 components, it symbolizes the precision of contemporary horology.
The Breguet Classique Grande Complication, with 13 complications, proves that technological sophistication and elegant wearability are not mutually exclusive. Its prominent tourbillon at 6 o’clock is paired with a perpetual calendar and retrograde displays. It epitomizes classical aesthetics combined with high watchmaking artistry and complex functions.
Pocket Watches: The Ultimate Expression of Complicated Watchmaking
When it comes to the absolute pinnacles of horology, pocket watches are impossible to overlook. The Vacheron Constantin Reference 57260, also known as “Tivoli,” was unveiled in 2015 to mark the manufacture’s 260th anniversary and is considered one of the most complex mechanical watches ever made, with 57 complications. It features a triple-axis tourbillon regulator, both Gregorian and Hebrew calendars, an astronomical module, and a Westminster chime. Eight years of development and more than 2,800 components make it a milestone of haute horlogerie and a highly coveted collector’s piece.
Even more spectacular is the Vacheron Constantin Berkley Grand Complication, currently recognized as the most complicated watch in the world with 63 complications. Over eleven years of development went into this masterpiece, which includes a Chinese perpetual calendar, a celestial chart over Shanghai, astronomical indications, a grande sonnerie chiming mechanism, and a triple-axis tourbillon regulator. Despite its immense complexity, it remains remarkably clear and aesthetically pleasing — a technical and artisanal monument to watchmaking.
