Watchlords

Nestled in Le Sentier, in the heart of the Jaeger-LeCoultre Manufacture, is a division dedicated solely to the building the famed Atmos clocks that almost runs on air.

Essentially powered by changes in atmospheric temperatures, the clock – made in some of the most elegant and unusual designs possible – can run continually without anyone touching it.
One of the most superb statement makers on the clock market, the Atmos Clock has been being built for almost a century and yet it is still as revolutionary today as it was when it was invented. In the Jaeger-LeCoultre Atmos clock workshops, approximately 50 technical experts work together to build and test these beauties.
