Atmos clocks are way beyond their time with the mechanism that they use to work. Incremental temperature changes are used to keep the watch running through the years without failing. These changes are useful when tracked by a bubble block of Baccarat crystal. The watches are powered up by a capsule that has a mix of gas and liquid ethyl chloride that causes a rise in temperature and this in turn compresses the spiral spring. Just an increment of a degree of temperature in the 15 to 30 degree Celsius range can keep the watch working for a whole two days.
The Atmos 561 timepiece has its bearings in time and promises to be an eternal companion.
