The Reason

This is a classic example of a 1950's triple date JLC with steel case, tear drop lugs. Entirely made by JLC the same design and mechanism was reproduced by Cartier and Vacheron Constantin in the same period by JLC for these houses. It is a historical representation of JLC's design and manufacturing expertise.


There is an extraordinary array of classic calibers in watchmaking, by numerous watch houses that have been developed, executed and found their way into history. This JLC is one of them, it is a work-horse of a caliber and with the exceptions created because of an early case which is not moisture resistant, could effectively live for ever. The over all movement design and proportions are perfect for classical chronometry and longevity.

The conical case back integrates a substantial mechanism and renders the case elegant and relatively slim. The overall design is complex and indicative of JLC from the early 1950's and late  1940's.
