I have an old key wind pocket watch given to me by my grandmother some 60 years ago. She told me it was handed down from her great-grandfather which would place it in the 1840's - 50's. When I open the back of the watch case, the back of the watch is brass colored and has the following words imprinted (starting at the top): Cylinder, Escapement, Four Holes Jeweled, hands, Vacheron, Geneva. There are two key stems...one to wind the watch and one to set the hands. At the bottom, below the word Geneva, the watch is numbered 30527. That same number is imprinted on the back of the silver colored case. There are no other marks on the back of the silver colored case except the letters VF. When I open up the brass colored back of the watch, the number 30527 is also imprinted on the back of the brass cover. I can find no other markings on the movement. The dial face numbers are roman numerals. The case is silvered colored. The dial face has a flower/vine scroll design in the center. The back of the case has a landscape scene with buildings and a man in a boat casting a fishing net. I have the key and the watch runs...including the small inset second hand. I have "Googled" the watch, and have learned that it was not made by Vacheron because the name Constatin does not appear and the writing is in English. Can someone tell from the photos if the watch is actually from before the Civil War? The inside of the silver colored case cover has the letters VF imprinted above the numbers 30527, which are imprinted near the bottom of the cover. Does that represent some sort of silver alloy/composition? The inside of the brass colored cover also has the number 30527 imprinted near the bottom and there is a letter "C" imprinted just to the right of the hinge. The hour and minute hands are very thin with pointed ends and are copper colored . Could Vacheron/Constatin produced inexpensive watch movements in the 1840’s with English inscriptions and just the Vacheron name, that they sold to American/British watch makers who then put on their own hands and dials and put the movements into their own cases or was this watch made by some other watch maker that just "used" the Vacheron name because of its prestige? Can you tell from the movement if the watch was made in Europe, Britain of the US? Any information would be greatly appreciated.?
