Antique watches

I have a pocketwatch in 18k with very fancy multi color gold face and case, with original bullseye crystal and diamond end stones in the movement.  It is signed Const. Jacot.   Is this a very early VC watch?
considering that Vacheron was the watchmaker and before

the partnership with Constantin certain watches only had the Vacheron name however no watches from VC featured Constantin without Vacheron so I don't think your watch is from VC, I would love to see a scan though.... 

it is from an English maker and not VC (nt)
