The 10-cm dial has baton hour markings and is inscribed ATMOS pendule perpetuelle. The straight hands are made of blued steel.
The movement is driven by a spring. This spring is wound by a mechanism which functions on changes in temperature. It causes a drum to turn. This turning motion winds the spring. The exceptional movement requires very little energy to run. With only one degree Centigrade temperature difference, the clock can run for 48 hours. The clock is regulated by a large horizontal balance wheel with adjusting screws which has a thirty second oscillation time. Since there are always changes of temperature during the course of the day, the clock is wound continually and will run continually. That is why Reutter called ‘Pendule perpetuelle’ (perpetual clock).
The rectangular case is made of black and red veined marble. Below the nickel plated door is a nickel lined aperture showing the balance wheel. The geometrical shape of this clock is typical for the Art Deco period. On the reverse is a plaque inscribed with Brevets J.L. Reutter s.g.d.g. made in France.
