The new Jaeger-LeCoultre Master Ultra Thin Perpetual watch exudes elegance and simplicity. Its clean dial displays the perpetual calendar with ease, thanks to the Jaeger-LeCoultre Calibre 868 nestled in a slim 9.2mm case. Despite its slim profile, the 39mm case provides a balanced platform for the different functions of the perpetual calendar, including day, month, year, and moon phase. With only one corrector, the watch can be set for up to 2100 without any need for adjustments. The perpetual calendar takes leap years into account, making it a reliable timepiece. Introduced at SIHH 2016, the Reference 1308470 boasts a black dial and stainless steel case.
