Thats a pretty interesting piece there, if only it could talk.
It looks like a mish mash of different eras has come together here in just one example. The movement is from likely a ladies pocket watch. The serial number on the movement dates it to 1916, a time before wrist watches as we know them.
The case is very unique. I have no resource to date the case by the serial number inside. The marks look a little suspect to me. It would at any rate be a custom case, the movement and case are "wedded" together in what is sometimes called a wedding watch. By its design, I would judge it to have come some 20+ years after the movement. Pretty unusual to have the crown at 12. I'm sure the size would be about 28-30mm.
The dial and hands bear only a passing similarity to anything Vacheron related, and would again be from a different era altogether.
I'm afraid your watch would have little market value. Although it is an interesting conversation piece and something nice to wear on occation.
There was a period when they made watches with the crown at 12, and now that you mention it, I may have seen one before.
What struck me is the age of the movement relative to the case style, quite a big gap. And while the size of the movement in the case looks good, the two movement retaining screws look a bit clumsy.
That style of hands, didn't they come much later, 1960's? The dial looks like it was preped for a redial, and not finished.
I guess that you would have to send it in to Geneve to have them sort it out for a difinitive answer. We can only speculate.
