A call was enough

In contrast to many other companies, when the war ended in 1918 Kapsch was able to build on its pre-war success. It continued to supply its customers in Prague, Trieste and Zagreb – and was able to intensify its relationships with the postal and telegraph authorities. The expansion of the telephone network and the construction of semi-automatic switchboards especially helped Kapsch to achieve good revenues.

Telephone with Retrofitted Dial


Telephones were expensive, which is why they were often modified as opposed to purchasing new models. This system was retrofitted with a dial. The postal and telegraph authorities introduced six-digit telephone numbers for the first time in 1927, the so-called ‘million system’.

Tabletop Telephone, ‘Carrying Ring Type’


This telephone was extremely practical: a ring was located in the center that allowed the telephone to be lifted up with a finger. This made it possible to carry the device and use it to make a telephone call at the same time.

Electric Clock Model A


Electric clocks may have been too modern for the public at the time they were invented. Production was discontinued after a few years. These electric clocks could be operated using both direct and alternating current and featured a power reserve of approximately 6 hours in the event of a power outage. Model ‘B’ could be supplied with an alarm function, while model ‘C’ featured a radio and an alarm clock function.
