Atmos Tuxedo


This Atmos Tuxedo clock, with an ornate banded front door, is a rare model. These clocks were made and sold by Le Coultre to high end jewlers. They were often used as presentation pieces celebrating accomplishments in life and/or career. The clock concept was developed by an engineer @ 1930’s. This model used a set of bellows filled with a special chemical which was very sensitive to temperature in terms of the volume it occupied. The variation in chemical volume caused the bellows to expand & contract this action was transmitted to a mainspring using a series of wheels & springs & a chain. Hence if the temperature changed enough and in the right range the clock never needed to be hand wound.
