Something a bit unconventional for this blog, mainly because it isn't a watch, but a clock. An Atmos clock is very peculiar, as it is wound by slight changes in temperature, which causes gas in the clock to expand and contract. When the temperature is between 15˚C and 30˚C, a change in as little as 1˚C can power the clock for two days. Any information about the technology can be found here. The movement, which essentially runs on perpetual motion, is the Jaeger-LeCoultre Calibre 568. The movement is hand-assembled from 211 parts. The perpetual moonphase indicator has a discrepency of 1 day every 3,861 years, which is unncessarily accurate. It is encased in glass. I've put photos below, I'd guess the price is around $6,000-$7,000 USD, but I haven't found any official figures.
