Jaeger-LeCoultre Atmos clock is created by Australian aircraft designer Marc Newson. Powered by minuscule changes in temperature, this clock can run for a long time on nothing but at least 1 degree of temperature change (Celsius) every 2 days. It is encased in a Baccarat crystal, and has a sky chart in the middle indicating the astronomical details of the sky in the Northern Hemisphere. There were only 48 of the clear models built and 28 of the blue crystals. This limited edition clock will cost you $2,600 each.
