Invented in 1928， the Jaeger‑LeCoultre’s Atmos clock utilises air as the source of energy. Not needing manual winding， the clock automatically winds itself by the expansion and contraction of gases due to temperature differences. Since then， the Atmos clock has been the Swiss government’s official gift for important guests. Besides its complicated and creative mechanism， the unique design allows the clock to be observed from every angle， giving the Atmos clock a classic and timeless character.
