1940 - 1960
Sold 16 December 2025 · Chalfont Clocks
This “Jaeger Lecoultre Atmos Clock with Original Bracket” found a buyer.

It was listed by Chalfont Clocks. Sold pieces stay on Sellingantiques as a record of what has passed through, and the next one is rarely far away.

Description

A beautiful Atmos Clock By Jaeger LeCoultre numbered 120482, with a square dial with gilded Arabic numerals and battens and smoked tip hands. Unusually this clock still has it’s original gilded wall bracket finished in a combination or grained and burnish gold plate.

This example dates from 1960 and the mechanism is housed in a gilt brass case with a brushed pedestal. The glass sides allow you to see the ingenious movement for all angles. These Atmos Clocks come in variety of designs, and this stylish example of Mid-Century design is one of our favourites.

The ‘Atmos’, first invented in 1928, has no external power source and never needs to be wound by hand. It isn’t powered by a suspended weight, as most pendulum clocks are. The Atmos clock gets its power from minute changes in atmospheric temperature, hence its name. Within a sealed capsule, a mixture of gases expand and contract with each temperature change. This is how the mechanism winds naturally without any human intervention.

This clock has been overhaulled and comes with our 2 year guarantee.

The Atmos clock is a mechanical timepiece manufactured in Switzerland by Jaeger-LeCoultre that does not need to be wound manually; it runs by sensing changes in temperature and atmospheric pressure in the environment.

These clocks are typically constructed with a brass or gilt metal casing, glass panels to showcase the internal mechanism, and specialized metallic bellows containing a gas and liquid mixture that expands and contracts with temperature shifts.

Authentication involves examining the serial number engraved on the movement, verifying the signature Swiss craftsmanship, checking the precision of the torsion pendulum, and inspecting the quality of the casing and glass panels.

An Atmos clock serves as a sophisticated focal point and can be placed on a mantelpiece, sideboard, or dedicated wall bracket where its intricate mechanical movement is visible and protected from vibrations.

Due to the extreme sensitivity of the torsion pendulum and perpetual mechanism, these clocks should be kept stationary on a rigid surface away from direct sunlight, and serviced only by specialized horologists every few decades.
