We are sorry, but this watch has already sold to another client
Since its introduction back in 2013, the Jaeger LeCoultre Master Ultra-Thin Perpetual Calendar has become one of the defining timepieces for JLC apart from the Reverso collection. The aesthetics and mechanical purity of the watch has attracted a fair share of collectors and devotees alike.
One of the differentiating points for the Jaeger LeCoultre Master Ultra-Thin Perpetual Calendar is the thin profile it possesses, measuring at a mere 9.2 mm in thickness, this makes it perhaps one of the thinnest perpetual calendars on the market. The streamlined lugs and sleek design of the bezel gives it an elegant look and class and this coupled with a stainless steel case that measures at 39 mm, makes this an ideal dress watch for collectors.
This model also features a single corrector located on the side of the case to allow for any adjustments to be made to the indications on the dial. It operates with a simple principle where one press would move the perpetual calendar one day forward, while any other changes required to keep step with the Gregorian calendar would happen automatically. One of the awesome features of the movement is its ability to take into account leap years and does not require any manual adjustment from the user before the year 2100.
The 2016 edition of the JLC Master Ultra-Thin Perpetual Calendar is powered by the mechanical automatic Jaeger-LeCoultre Calibre 868 which is the same movement used in the 2013 release.
The movement operates at 28,800 vph and comprises of a total of 336 parts which is a remarkable feat given the fact that the dimension of the watch measures only at a thin 9.2 mm thus the need for a compact design in order for it to be housed within the timepiece.
The movement has a 38 hours power reserve which is reasonable and looking closer at the movement, we can see a skeletonised rotor with its oscillating mass in gold which allows for a clearer view of the movement. In addition, the Côtes de Genève finish on the movement completes the look of pure excellence.
