Jaeger-LeCoultreThis Atmos perpetual motion clock by Jaeger-LeCoultre is housed in a gilt brass case fitted with glazed panels. The source dates the timepiece to circa 1970. It operates via an 11-jewel movement with a torsion pendulum mechanism designed to be powered by environmental atmospheric variations.
The front displays a white chapter ring featuring Arabic numerals at the three, six, nine, and twelve positions alternating with dart-shaped hour markers, paired with gilt hands over an open skeletonized center that exposes the movement wheels.

- Visible features
- • Rectangular gilt brass case with glazed side, front, and top panels. • White chapter ring inscribed 'LECOULTRE' below 12 and 'SWISS' below 6. • Arabic numerals at 3, 6, 9, and 12 alternating with applied dart hour markers. • Skeletonized center revealing brass gears and movement plates. • Fluted cylindrical torsion pendulum balance suspended below the movement frame.
- Case Construction and Dimensions
- The clock is housed in a rectangular gilt brass case fitted with glazed front, side, and top panels. Direct visual observation confirms the glazed panels enclose the internal movement components and pendulum. According to the seller's catalog entry, the overall exterior dimensions measure 9 1/2 inches high by 8 inches wide by 6 1/4 inches deep.
- Dial Display and Movement Visibility
- The dial configuration features a white chapter ring encircling an open center that reveals internal brass gears and movement plates. Direct visual observation records the dial markings as 'LECOULTRE' placed below the 12 position and 'SWISS' positioned below 6. The hour track includes Arabic numerals at the 3, 6, 9, and 12 positions alternating with applied dart hour markers. The seller listing describes the hour markers as sword and Arabic markers with sword hands on a white enamel chapter ring.
- Reported Mechanism and Documentation Limits
- The clock incorporates an 11-jewel movement with a torsion pendulum mechanism reported by the source to be driven by environmental changes in atmospheric pressure and temperature causing gases to contract and expand. A fluted cylindrical torsion pendulum balance is visibly suspended beneath the movement frame. The seller dates the clock to circa 1970, although specific caliber designations, reference numbers, and serial stamps are neither recorded in the source text nor legible from the frontal photograph. Commercial claims stating that the piece bears a complete restoration and a one-year warranty represent unverified vendor assertions.
