Hybris Mechanica à Grande Sonnerie (2009)
Jaeger-LeCoultre’s most complex watch
Price: Estimated at US$1.5 million but only offered in an exclusive set of three watches worth US$2.5million
One of the most complex timepieces in the industry, the 30-piece limited-edition supercomplication in a white gold case, measuring 44mm in diameter and 15mm thick, was first presented in 2009 as a concept piece, which then required an additional five years to finetune. More than 1,300 people worked on the production of the 1,472-part watch and it takes nine months for one watchmaker to assemble the timepiece. The manually wound Calibre 182 movement features a minute repeater, petite sonnerie and grande sonnerie with full Westminster chimes that plays the longest melody ever chimed by a striking timepiece; it also comes complete with the proprietary monobloc crystal gongs and trebuchet hammers that contribute to better resonance. Additionally, the watch also showcases a perpetual calendar, flying tourbillon and two power reserve indicators contained in the classic Duomètre case. One of the most advanced movements ever created for a wristwatch, the brand didn’t merely conceive a new minor adaptation based on existing striking watch concepts, but completely reassessed and improved the main principles of musical mechanisms by relying on its experience and savoir faire acquired over the past 182 years, a period over which it developed and produced more than 1,242 calibres.
