History of this interesting VC keywound

Hello all,

I am wondering on the history of this strange VC pocketwatch which has crossed my path. I have dealt with a few watches, but nothing as "old" or like this one before, especially a keywound. What confuses me is the lack of information on the movement, as well as "Vacheron & constantin" instead of the just Vacheron Constantin. Is this some wonderful old watch or just a knock off?

Here are images (sorry if I posted them incorrectly).

Hi Alex, On the case it says "1443". No numbers on the movement. Many thanks
