A rare Art Deco nickel plated Jean Leon Reutter patent atmos clock, type J1, circa 1935.
The chapter ring
The 13-cm silvered chapter ring has Arabic numerals. It is inscribed below 12 ATMOS and above 6 Pendule Perpetuelle. The painted hands have black tips.
The movement is attractively visible from all sides and is driven by a spring. This spring is wound by a drum that turns by means of temperature changes. Since the movement needs very little power to operate, it runs for 48 hours with one degree of temperature change. The large balance rotates every thirty seconds. The bracket holding the drum is numbered 5540 and marked Brevets J.L. Reutter S.G.D.G.
The rectangular case is made of nickel plated brass and has beveled glass panels on all sides. The flat plinth holds the lever for fixing balance for transport or handling.
