In addition to the famous drop-shaped kitchen clock with a short timer, Max Bill also created wall clocks in cooperation with Junghans around 1958/59. There are three different versions of the clock with the lines, one chromed and two different with brass case.
One brass-case model has a case with only a very short rim, the dial is moved far to the front of the clock. This model has no glass and 30 cm diameter. It cost 120,- DM at that time. The reference number is: 322/0350
On the other brass version (here from the collection @sheldinkee, Australia), the movement is in a deep case and it is equipped with a glass. This version has got a diameter of 24 cm and cost 123,- DM at that time. The reference number is: 322/0411
The third version (reference number 322/0389) has a chrome-plated case, a diameter of 30 cm, cost 140,- DM and is equipped with a glass.
All three variants carry an electromechanical movement. It is an "Electora" folding pallet lever movement Junghans W285.
The clock has a diameter of about 30 cm.
The clock is powered by the caliber Junghans W285, which was manufactured between 1956 and 1962. A spring is tensioned by a hinged anchor, which drives the pin lever movement. If the anchor sinks slowly, it triggers an electrical contact, which throws the anchore upwards again by means of a magnetic coil.
