Of course we could mention many great movements from Jaeger Lecoultre. They made,since 1833, more than 2000 movements, so the list can be endless, such as the Cal 889, the 38x from the Duometre line, the Gyrotourbillons, and, of course, the vintage calibres such as those of the Geophysic, Futurematic, the Memovox...
Here, I would just show two of them, one which is the thinnest, the Cal 849, and the smallest, the cal 101.
Being the smallest and the thinnest movement is a true technical and horological defy, and at that game, Jaeger Lecoultre is a champion.
- The Cal 101, first.
Did you know that this movement was born in... 1929? Can you imagine the necessary amount of skill and talent to produce such a movement at that time?
Here you have a movement which is 14 x 4, 8 mm big and 3, 4 mm high, made of 98 parts, beating at 21, 600 vibrations per hour, and offering a modest power reserve of 33 hours.
The other remarkable detail is that after all these years, 91 years, it is still housed in some watches of the current collection. How many movements can claim such longevity?
The Reverso Cal 101, a limited edition of 5 pieces in white gold, XGT case:
- The Cal 849.
Born in 1975 under a slightly different reference, the Cal 839, when the Quartz almost killed the traditional mechanical movements, it had to be daring to decide to make such a movement. It is small, with a diameter of 20, 20 mm, but the most impressive feature is its thinness, with a height of only 1, 85 mm for 123 components. It beats at 21, 600 vibrations per hour and offers the same power reserve as the Cal 101 ( 33 hours ).
It is housed in the thinnest modern definitive watch, the Master Ultra Thin Enamel Skeleton, which is 3, 6 mm high.
Both of these movements are an important and very interesting part of JLC Patrimony. They are the heart of some horological marvels, too.
It was fair to give them some attention.
