A rare Art Deco nickel plated Reutter patent atmos clock type P01, circa 1930

Description

The chapter ring

The 13.5-cm silvered chapter ring has Roman numerals and is inscribed ATMOS and pendule perpetuelle. The hands are laquered white with black tips.

The movement

The attractively visible movement is driven by a small spring. This spring is wound by the turning motion of a drum which are caused by changes in temperature. The movement requires extremely little energy to run and it needs only one degree temperature change to be able to run for another 48 hours. The large balance wheel with attractive large rating screws revolves every thirty seconds. The back is numbered 5430 and marked Brevets J.L. Reutter S.G.D.G.

The case

The skeletonised movement is placed on two nikkel plated supports mounted on a black marble base raised on arched nickel plated feet. The whole under a glass dome.
