Hello, I would like to show you this interesting regulator clock. Dial clock is signed "FRANZ HECKEL IN WIEN". The precision of this clock is very good. I love this kind of clocks for two reason: cases are often very nices, and also accurate time perfectly. You can see here some pictures. Does any have some information about FRANZ HECKEL?. Is this name a clockmaker name?, a company name?, a clock seller name? I really apreciate all information, opinions, etc, about this piece. Thank you in advance, and let´s take a look to the clock. Best regards, Miguel.
