Atmos I

Based on a 1928 concept by Swiss inventor Jean-Léon Rutt who entrusted its development and production to the Manufacture Jaeger-LeCoultre, the Atmos is the first clock with a perpetual movement. This model, called Atmos I, dates from 1934 and contains at its heart the LeCoultre 30A perpetual winding calibre, the first calibre manufactured by LeCoultre & Cie for Atmos. The rhodium-plated cabinet is composed of four glasses in the centre of which a round silvered dial with straight arrow markers and leaf hands in two shades of colour stands out. Perpetual LeCoutlre Calibre 30A.
