The history of this Jaeger-LeCoultre Atmos Malachite
Jaeger-LeCoultre offers a unique approach to timekeeping with the Atmos clock. Invented in 1928 by the engineer Jean-Léon Reutter, this creation is based on a mechanical principle that operates using variations in ambient temperature. The 5905 model features a 1980s aesthetic, incorporating decorative panels that mimic hard stone. The Swiss government traditionally presents an Atmos to heads of state on official visits, cementing the status of this desk ornament. This model embodies precise and masterful mechanical engineering.
Case, movement and strap of this Atmos Malachite
The timepiece rests on a stepped base in polished gilt brass. The case features fluted sides framing green lacquered panels. These surfaces replicate the layered appearance of malachite. The central dial echoes this deep green motif and displays black Roman numerals on a brushed ring. The gold hands indicate the time clearly. The movement is powered by the calibre 528. A sealed capsule containing ethyl chloride expands and contracts. A temperature variation of just 1 degree Celsius is sufficient to provide a 48-hour power reserve. The lower ring balance oscillates slowly to minimise friction. This table clock is displayed directly on its plinth.
Why this Jaeger-LeCoultre clock
Acquiring an Atmos clock from this era is a discerning choice for a collector. The malachite-effect finish adds a striking touch to any interior. Finding a 1983 model accompanied by its original documentation represents a tangible opportunity on the second-hand market. It offers a genuine mechanical alternative to contemporary clocks.
