Atmos Classique Phases de Lune Clock

An ingenious clock that never stops ticking, running solely on air.

Almost 100 years after its debut, Jean-Léon Reutter’s revolutionary winding mechanism continues to wow even the most discerning horology experts. The simple yet ingenious device relies on the contraction and expansion of gases to keep the movement of clocks like the Atmos Classique Phases de Lune beating in perpetuity. Even a seemingly insignificant change of one degree Celsius is enough to power it for 48 hours. The collection is not only exceptional performance-wise – its elegance and timelessness have also captured the attention of great designers, who have reinterpreted it with their own verve and style.
