The Atmos Classic Bicolor has a platinated polished case and a round white dial with black Roman numerals. This timepiece is newly revised and in immaculate condition.
The Atmos (for atmospheric clock) takes its energy from from the expansion and contraction of a capsule filled with ethyl chloride gas that responds to changes in temperature and barometric pressure. The produced energy winds the mainspring. According to the makers of the clock, a temperature difference of 1 Kelvin creates a power reserve of approximately 48 hours.
