~ Cased Atmos Clock By Jaeger LeCoultre c1950’s ~
A very stylish Swiss-made Atmos Clock by Jaeger LeCoultre complete with case dating to the late 1950’s.
Atmos clocks are known as perpetual motion clocks, as they require no winding. They work by using a thin hairspring located at the top of the clock and an aneroid chamber mounted on the back of the movement via which the clock is able to detect changes in temperature which regulates the accuracy of the movement. Apparently even a one degree change in temperature is sufficient to wind the clock for two days' duration.
The brass clock is housed inside a gilt metal framed glass case with front opening door.
The clock has a white chapter ring dial through which you can see the movement; this is surrounded by a gilt brass bezel.
The dial has both Arabic numerals and baton hours and features two gilt, dagger style hands with blackened tips.
The clock is marked ‘Swiss Made, Jaeger LeCoultre, ATMOS’.
The clock has a ‘526-5’ movement with a serial number of ‘124534’.
The underside of the clock reads ‘LeCoultre & Cie, Metal, Calibre 526-5, Swiss’.
The clock comes with an original Jaeger LeCoultre fitted hard case and original instruction booklet.
