This watch was launched as a special edition in 2013. The Master Grande Traditional Tourbillon Quantieme Perpetual Jubilee Edition is Jaeger-LeCoultre’s complicated watchmaking at its finest. Based on a 42mm by 13.1 mm platform in Platinum with a silver toned dial, display case back, and a gorgeous layout that balances a flying tourbillon as well as a perpetual calendar display spread across three sub dials. The case is finished with its lugs and bezel polished and its flanks in satin.

JLC went all out when it came to the movement cased within. Using the automatic calibre 985, the Cylindrique Perpetuel is comprised of 431 parts which support the 48 hour power reserve and a frequency of 28,800 vph. The movement is hand built and entirely finished by hand with an oscillating gold weight that bears the design from the medallion that Jaeger-LeCoultre won at the 1889 Paris Universal Exposition. With hours, minutes, seconds (via the tourbillon), as well as day, date, month, year and moon phase (within the date sub dial at three), complexity is the name of the game, even before we get to the tourbillon details.

With a titanium carriage, 14-carat balance and a cylindrical balance spring, this flying tourbillon looks as though it’s floating in place at the six position on the dial. With the combination of the tourbillon and their perpetual calendar technology, Jaeger-LeCoultre claims that the Cylindrique Perpetuel is the world’s most accurate perpetual calendar.
