The Hybris Mechanica Grande Sonnerie will hold the Jaeger LeCoultre mechanical Calibre 182 movement with 26 complications and over 1300 parts. All of that will be inside of the 18k white gold 44mm wide by 15mm thick case. I honestly don't know how they will be able to cram the ultra complex movement and complex chiming and gongs mechanism into such a small space. I am starting to understand where the huge price comes into play. The last two "world's most complex watchess" were the Patek Philippe Calibre 89 which boasted 24 complications and cost $6 million, and the Franck Muller Aeternitas Mega that had 25 complications and cost (only) $1 million. Soon these watches will be supplanted by the Hybris Mechanica Grande Sonnerie. The collection of three watches that will come in the Hybris Mechanica set will together hold 55 complications. For the serious collector, and serious price of the watch, it is clear why they will be delivered in a safe.
So what does the watch do? Many of the complications involve the sonnerie functions that include Westminster chimes (will be the only watch that can play the whole Westminster carillon melody), grande sonnerie, petit sonnerie, minute repeater, a silent mode, flying tourbillon, perpetual calendar with a retrograde day, date, and month indicator as well as a leap year indicator. The watch will of course have the time, with an instantaneous jumping hour display, as well as separate power reserve indicators for the mainspring power reserve as well as the power reserve for the sonnerie. There is frankly too much to discuss in terms of all that is seemingly impossibly included in this incredible timepiece. I am most impressed that despite the many complications, the watch still is able to have a large portion of the dial skeletonized and still be highly easy to read. More details soon as the Jaeger LeCoultre Hybris Mechanica Grande Sonnerie is closer to release.
