Jaeger-LeCoultre ATMOS Classique Phases de Lune Gold-Plated (5111202)

The Jaeger-LeCoultre ATMOS Classique Phases de Lune clock (ref. 5111202) features a hermetically sealed automatic movement, gold-plated & transparent glass cabinet revealing its impressive horological movement, visible winding mechanism, moon phase complication and month display. Dimensions: 9.8" (25.0cm) height x 7.3" (18.5cm) width x 5.5" (14.0cm) depth.

ATMOS clocks are technical marvels. Inside each clock is a hermetically sealed capsule that contains a mixture of gas and liquid that expands as the temperature rises and contracts as it falls. This motion constantly winds the mainspring, a variation in temperature of only one degree centigrade being sufficient for two days' operation.

Every ATMOS clock is made entirely by hand, and with some models, a single clock takes a month to produce. The incredible precision of the ATMOS' manufacture produces clocks that have an expected service life of over 600 years.
