Stunning German Olympia Jerger with the hearts mechanism and roman numerals, ca.1960s. This is one of the most beautiful versions of Olympia clocks.
I am not aware of any black version of this timer so probably it was painted black at some point.
The condition is good considering the age. Both clocks run fine and have been tested for a few hours.
