An amazing mantle/desk clock with quite a history. Designed by esteemed manufacturer Jaeger LeCoultre about a century ago, the Atmos clock requires no batteries, winding, or light. So how does it work?

It uses the regular changes in atmospheric pressure (what your barometer shows) to wind its mainspring. This powers the clock.

Recently, Jaeger LeCoultre has released Transparent models, updating the classic look. The one shown here is the "Atmos Classique Phases de lune Transparente" , which displays the time, date, month, and lunar phase.
