Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

An Atmos clock is a mechanical timepiece manufactured by Jaeger-LeCoultre that derives energy from minute temperature and atmospheric pressure variations in the surrounding environment. First developed in the late 1920s, it uses a sealed capsule containing ethyl chloride gas that expands and contracts to wind the mainspring without manual winding.

Mid-twentieth-century Atmos clocks are typically housed in a gilt brass frame with five bevelled or plain glass panels. Internal mechanisms feature brass gear trains, a heavy rotating balance wheel suspended by an elinvar wire, and a painted or lacquered dial.

Authentic Atmos clocks feature the Jaeger-LeCoultre brand marking on the dial or movement face, along with a stamped calibre number and unique serial number. Additionally, authentic models possess the characteristic slow-rotating balance wheel suspended at the base, completing two beats per minute.

Positioning an Atmos clock on a dark wood mantelpiece, a structured sideboard top, or within an executive desk shelf creates a defined focus. Its transparent glass housing allows light to pass through, pairing well with contemporary minimalist or mid-century interior schemes.

To preserve an Atmos clock, place it on a strictly level, vibration-free surface and engage the pendulum locking mechanism whenever moving the piece. Dust the exterior glass and brass case gently with a soft microfibre cloth without applying liquid chemical cleaners.
