Jaeger-LeCoultre’s newest Atmos is an exceedingly clear expression of clock-sized mechanical timekeeping. The beautiful new Art Deco dial within this new Atmos Transparente seems to float inside six glass panes that have all been treated with a new anti-reflective coating to better reveal the essentially simple, air-temperature-powered clock within.
Even the dial, stylized as it is, is an artistic work in glass that echoes its minimalistic housing. The Deco hour-markers and hands are spare, cloaked in black and quite visible. The clock’s base is satin brushed and rhodium plated, matching the barely noticeable movement plate and base within the case.
Jaeger-LeCoultre’s Atmos is possibly the best-known, ongoing clock collection within the pantheon of high-end Swiss watch manufacturers. Only Patek Philippe’s dome clocks and Cartier’s mystery clocks reach the same level of historical and technical significance within the world of watchmakers as Atmos.
As a reminder, the Atmos clockworks are powered by a mechanism that translates small changes in air temperature into motion. Invented by engineer Jean-Léon Reutter in 1928 and brought to market by Jaeger-LeCoultre in the 1930s, the Atmos clock can operate for two full days with just a single degree of variation in the room temperature. Price: $9,450.
