Atmos clocks are made by the renowned Swiss company Jaeger LeCoultre. Atmos regarded as a reference among clocks, the Atmos has been literally living on air since 1928.
Invented by Neuchatel-born engineer Jean-Leon Reutter, then developed and relentlessy fine-tuned in the workshop of the Manufacture, the Atmos clock measures the flow of time with a faithful continuity unaltered by the passing of years.
It's prodigiously creative perpetual winding principle is based on a hermetically saled capsule filled with mixture of gases,wich expands when the temperature rise and contracts as it falls. Interdependent with the mainspring of the clock, the capsule constantly winds the clock movement. A mere one-degree temperature fluctuation is enough to provide the watch with a two-day power-reserve.
