LeCoultre & Companie Atmos mantel clock. Produced by Jaeger - LeCoultre & Compagnie. Swiss, ca. mid 20th century. The Atmos clock is a masterful piece of engineering. It operates solely on changes in temperature and barometric pressure; quite simply, it runs without batteries, winding, or any sort of input for years on end. This example runs and sets. Minor wear on exterior, clock seems to work great. 9 3/16" tall by 8 1/4" wide by 6 1/2" long.
