Atmos Classique Phases de Lune from Jaeger-LeCoultre

It has been over 85 years since the Atmos, from Jaeger-LeCoultre has been on the horological stage for its extraordinary technical achievement. It has the most precise moon-phase display in the history of horology and is accurate to a single day every 3,821 years and another dial with months that are indicated on openwork disc at the centre of the dial.

The classical pink gilt cabinet of the new Atmos is the epitome of restraint and purity and this is the third variation of a model that also comes with a yellow gilt or rhodiumed cabinet. Each Atmos has to undergo weeks of trials and adjustments before it is allowed to leave the workshops where the clockmasters at Jaeger-LeCoultre are aware that it is their job to guide the first steps of a mechanism destined to far outlive their own human lifespan.

The Atmos clock lives from generation to generation and celebrates countless special moments, bordering on the perpetual. It is this vocation as a messenger and a witness to time that gave rise to the idea of offering personalised engraving of Atmos clock windows. Its glass cabinet may be silkscreen-printed, thus enabling meticulous craftsmanship suited to the executing of sophisticated lettering and motifs.

The Atmos, which was invented in 1928, counts the hours, day after day, year after year, without any need for a battery or rewinding and is a clock that lives on air. It works with the help of the hermetically sealed capsule positioned at the back of the mechanism which can transform variations in ambient temperature into mechanical energy. Each time the latter rises or falls by a single degree centigrade, the mechanism is able to store up enough energy to guarantee 48 hours of operation. Only the balance’s extremely slow oscillating speed and its suspension from an incredibly fine Elinvar wire guarantee the mechanism’s ability to continue functioning unassisted across the centuries.
