This is what I know, if any of this is wrong please correct. This watch is a 14K full hunter case with an unsigned movement and face. The case has the collective responsibility mark no 2, the hammer with handle. With the number "39" inside the hammer head. Research tells me that this mark is pre 1966. The pre 1995 swiss gold mark is the "583 squirrel" with an "L" inside the stamp. That tells me that the assayers office was Le Locle. There is a crown style mark that I have not been able to attribute.
This is a quarter repeater, lever type, with wire bell, there is a strange star shaped "gear" that sticks up from the movement and spins when the watch chimes.
There is a repair date from 1984 scratch inside the movement back cover. The front cover has a serial number of 0572, and the back cover has a serial number of 20572.
This is what I don't know.
Who was registered the number "39" for the collective responsibility mark?
Who were the prime contracts for this case maker?
Is the movement identifiable in any way, as to age and house?
As a side note I purchased this watch in Prague from a reputable dealer, in a small shop selling antique watches and clocks.
Attached are several pictures that I hope will help.
Any response will be helpful.
