2024 Watch - Jaeger-LeCoultre Master Ultra Thin Perpetual

The Jaeger-LeCoultre Master Perpetual Calendar was first launched in 2013. It is an ultra-thin perpetual calendar that combines the IWC "one-button adjustment" perpetual calendar module with the Jaeger-LeCoultre 899 automatic movement. Jaeger-LeCoultre and IWC are both members of the Richemont Group, and their technologies are interoperable. The Jaeger-LeCoultre Master Perpetual Calendar has the convenience of "one-button adjustment" perpetual calendar, while maintaining the consistent ultra-thin thickness of the Jaeger-LeCoultre Ultra-Thin Master, and the price is reasonable.

From 2013 to 2023, the Jaeger-LeCoultre Master Perpetual Calendar has no other changes except that the automatic rotor was replaced once in the middle, from the steel rotor to the current gold rotor. But the old Jaeger-LeCoultre Master Perpetual Calendar, with a power of 38 hours, was acceptable in 2013. But today, 60, 70 hours, or even more than 100 hours of power are very common, and 38 hours of power is not enough. Jaeger-LeCoultre has also realized this problem, and has been upgrading the 70-hour power movement on a large scale since 2020. With the Master Calendar, Master Moon Phase, and Polaris series all replaced, it is finally the turn of the Master Perpetual Calendar this year.

After upgrading to 70 hours of power, the movement models of Jaeger-LeCoultre remain unchanged. The new Master Perpetual Calendar is still the 868 automatic movement. The appearance of the movement has not changed either, and it is obviously a pure upgrade of the barrel (or spring). The movement decoration of Jaeger-LeCoultre has always been exquisite. The lower movement plywood is full of pearl patterns, the upper plywood is decorated with Geneva stripes, the edges of the plywood are chamfered and polished, and the exposed screw heads are blued. The all-gold hollow automatic rotor with the Jaeger-LeCoultre JL logo is very luxurious without covering the movement.

The size and thickness of the new Jaeger-LeCoultre Master Perpetual Calendar have not changed, and it is still 39 mm and 9.2 mm thick. The amazing thing is that the thickness of the Master Perpetual Calendar is a little thinner than that of the Master Moon Phase. It can be seen how outstanding the "one-button adjustment" perpetual calendar module and the lower Jaeger-LeCoultre 899 automatic movement are in controlling thickness. On the side of the case, we can see a "hidden button". This is the adjustment button for the "one-touch adjustment" perpetual calendar. Press it with the adjustment needle, and all the days of the week, calendars, and moon phases will move forward one day. One button adjusts everything, and it is set for you, which is very convenient. This is the advantage of Jaeger-LeCoultre and IWC perpetual calendars (but be careful not to press too much, or you can't adjust it back if you adjust it too much, you can only stop the watch and wait until the correct date).
