Jaeger-LeCoultre Master Grande Tradition Tourbillon Cylindrique à Quantième Perpétuel
The world’s most accurate perpetual calendar. Inspired by its 19th century predecessors, this watch is said to be the world’s most accurate perpetual calendar because of the advanced technology that powers it. Within its 42 mm pink gold case, the automatic winding mechanical movement  Jaeger-LeCoultre Calibre 985 beats to the rhythm of a flying tourbillion, equipped with a cylindrical balance-spring for precision timing. The tourbillon’s grade 5 titanium carriage, its large 14-carat balance and its cylindrical balance-spring create an impression of levitation: the tourbillon appears to be suspended in mid-air at the heart of the movement. The perpetual calendar provides a crystal-clear display of the day, date, month and year, alongside with the moon phases, while the small seconds hands is located above the flying tourbillon. Power reserve of 48 hours

The bezel is in satin-brushed and polished stainless steel or 18-carat pink gold, secured by the brand’s signature eight polished steel hexagonal screws.

IWC Aquatimer Perpetual Calendar Digital Date-Month04_IWC_Aquatimer_IW379401_front
This 49-mm limited edition watch (50 pieces) in a rubber-coated titanium case with an 18-carat red gold bezel is the second-largest wristwatch in IWC’s history after the Big Pilot from the 1940s. In order to advance its large month display discs, the watch requires more power than the in-house automatic 89801 calibre can provide. For this reason, every night when the date display is advanced, the quick-action switch taps a little energy and stores it until the end of the month. The date and month discs have semi-transparent perforated covers that provide a view of the complex mechanism within.
