Kasper: Watches and Movements – Part 1

As with a number of manufacturers in the watch and jewelry town of Pforzheim, the history of Kasper & Co., founded in 1911 by Karl and Christine Kasper, did not begin with watches, but with elastic straps for watches.

Accordingly, in some cases it is difficult to find the manufacturer or an exact caliber designation.
