Regarded as a reference among clocks, the Atmos has been literally living on air since l928. lnvented by Neuchatel-born engineer Jean-Léon Reuttet, then developed and relentlessly fine-tuned in the workshop of the Manufacture, the Atmos clock measures the flow of time with a faithful continuity unaltered by the passing of years.
lts prodigiously creative perpetual winding principle is based on an hermetically sealed capsule filled with a mixture of gases, which expands when the temperature rises and contracts as it falls.
lnterdependent with the mainspring of the clock, the capsule constantly winds the clock movement.
A mere one-degree temperature fluctuation is enough to provide the watch with a two-day power-reserve.
The secret of the Atmos clock is undoubtedly lies in its movement requiring an incredibly small amount of energy to operate.
lts balance moves at a majestically slow pace, vibrating only twice a minute.
lt hangs from a thin yet exceptionally stable and resistant steel alloy wire that is finer than a hair and keeps any losses due to friction to an absolute minimum.
The gearing is so perfect that it requires no lubrication and oil itself would simply clog the mechanism.
