SIGNED JAEGER-LECOULTRE, ATMOS 561 MODEL, NO. 313/888, MOVEMENT NO. 734'805, CIRCA 2008

The movement of the Jaeger-LeCoultre Atmos clock harvests its energy from temperature and atmospheric changes in the environment. To do so, it not only draws energy from a sealed airtight capsule of mixed gases that either expand or condense when the temperature changes, but it also requires a very innovative and amusing mechanism known as the torsion pendulum, which is inspired by the traditional clock. Unlike a pendulum clock, which requires manual winding with a key and consists of the swaying movement of a pendulum to act as a harmonic oscillator for accurate time keeping, a torsion pendulum uses a weighted wheel that oscillates in a movement similar to the balance wheel of a watch, and most importantly requires less energy to operate than a traditional pendulum clock. The Atmos clock has been very popular among collectors since its introduction in 1928 and has served as official gifts for the Swiss government.

Marc Newson who has brought a new twist to the traditional form of the Jaeger-LeCoultre Atmos clock has also designed for Apple, Nike, Hermés, Leica amongst others. Unlike the traditional Jaeger-LeCoultre Atmos clocks, the present Atmos 561 model ignites a new spark to the design of this historically famous timepiece by incorporating a Baccarat crystal case. The case is shaped like an ice cube and when seen from afar, the rounded lines of the crystal can deceive spectators in seeing a floating dial and movement.

The present clock is number 313 of a limited edition of 888 examples made to commemorate the 80th anniversary of Atmos Clock in 2008.
