Jaeger-LeCoultreThe Jaeger-LeCoultre Atmos du Millenaire 'Atlantis' is an atmospheric clock designed to function through changes in barometric pressure and temperature. The clock features a stainless steel and glass housing, constructed with bevelled glass panels and supported by three conical stainless steel feet.
It incorporates an inset spirit level for stabilization. The white lacquered dial displays painted baton hour indexes and an inner minute ring, complemented by blue painted month indications and a moon phase aperture with a lunar calendar. A distinct feature is the outer spiral scale calibrated to track years through the year 3000. It is powered by a vacuum chamber that winds the mainspring, utilizing an annular tension pendulum and a lever escapement.
The mechanism includes a locking lever for the pendulum. The clock is documented as being produced in a limited series starting in 1999.

Design
- Movement
- The movement is constructed from stainless steel and relies on the Atmos system of energy generation. A vacuum chamber responds to fluctuations in temperature and barometric pressure, providing energy to wind the going barrel. The manufacturer notes that a temperature variation of one degree is sufficient to power the clock for two days of operation. The escapement is a lever type driven by an annular tension pendulum. A locking lever is positioned above the pendulum disc for safety or transport, and the regulator is located at the top of the assembly.
- Case and Dial
- The Atmos du Millenaire 'Atlantis' is housed in a wedge-shaped case constructed from bevelled glass panels. The structure is elevated on three conical stainless steel feet and includes an integrated spirit level to ensure proper horizontal positioning of the mechanism. The visual profile is defined by the transparent enclosure which allows for view of the internal movement and pendulum. The white lacquered dial features painted baton hour indexes and an inner minute track. It incorporates a blue painted disc for month indications and a dedicated aperture showing moon phases alongside a lunar calendar. The primary complication is an outer spiral scale calibrated to indicate years up to the year 3000. Time is displayed via blued hour and minute hands, while a separate white and blued hand serves the year indicator.
- Visible features
- • Exterior is composed of bevelled glass panels with stainless steel supports. • Dial includes an outer spiral scale for 1000-year tracking. • The movement utilizes an annular tension pendulum with a locking lever. • Includes an integrated spirit level at the base.
- Condition and Attribution
- The auction description reports that the object is in very good condition across all primary categories. Specifically, the case, movement, and dial are all graded as '2 Very good'. The hands are noted as original to the piece. The clock is identified as part of a series produced by Jaeger-LeCoultre starting in 1999, with an intended annual production limit of 50 units. The case is signed by the maker.
