Found an old picture in an old book and...
The clock was made by an ancestor (?) a Ducommun from La Chaux de Fonds, Switzerland, the watchmaking Capital in the past. My FIL graduated from the Watchmaker School, came to the US in the twenties and worked for Bulova Company in NY before coming to California in the thirties to open his own Jewelry Store and watchmaking business.
FIL never mentioned his ancestor, never talked much about his roots, I found this picture in an old book.
I can't imagine the work that went into this`piece, it shows time, date, signs of the zodiac, and all mechanical.
Google Francois Ducommun, you get some more info and amuch better picture of this master-piece, in the Watchmaking Museum
