Replica Jaeger-LeCoultre

LeCoultre & Cie, located in the small Swiss village of Le Sentier in the Jura Mountains was the original owner of LeCoultre trademark. However, in 1985, Jaeger-LeCoultre officially replaced the former trademark, after it expired.

Jaeger LeCoultre manufactured the famous Atmos, which is a non-winding mechanical clock. One of the most unique features of the model is its capability of independently deriving its total energy requirements from small changes in its environment. Minute changes in temperature or atmospheric pressure are sufficient to serve this purpose. It requires no human involvement whatsoever to function with unproblematic efficiently.

Jean Leon Reuter of Neuchatel, Switzerland, who was an engineer by profession, designed the initial Atmos in 1928. It is generally agreed that the clock unofficially called Atmos 0 was invented prior to the 1928 model. However, this was a non-commercial trial model that operated by an expansion device, containing mercury in an inbuilt glass tube. Even the smallest alteration of a degree in temperature was sufficient to self-wind the clock for a continuous use of up to two days.

Manufacturing of the first marketable model of Atmos 1, that used ammonia and mercury power source, was commenced in France in 1929. Consequently, its commercial production was taken over by the company in 1935. A second version of the model, later on to be named Atmos 2 was initially developed and publicized in 1936. This model used ethyl chloride alternate power source, which has remained in constant use till today. However, due to persistent problems, its full production failed to start until 1939. Successive models have successfully produced more than 500,000 clocks, based on the original design.

Timepieces available as Jaeger-leCoultre replica watches, perfectly copied from models of the famous original Atmos collection, are a constant source of inspiration that can be readily compared to the devotion displayed by its creators.
