A large French art deco nickel Reutter patent atmos clock, circa 1930.


The dial

The 11.5-cm enamel dial has Roman numerals and is inscribed ATMOS pendule perpetuelle and Brevets J.L. Reutter. The blued steel hands are of the Breguet type.

The movement

The movement is attractively visible from all sides which is an attractive feature. It is driven by a small spring which is wound by the turning motion of a drum. This turning motion is 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 2235.

The case

The rectangular nickel plated case has beveled glass panels on all sides and top. To the front and back are doors. The whole is placed on a canted plinth. The height of this case is unusually large which makes this clock quite rare.
