Is this a WW1 era VC ebauche?

I am a keen but fairly clueless collector of WW1 era trench watches. I have seen a watch with a movement like one of mine where the the movement is described as being based on an ebauche by Vacheron. Here is a picture of the movement of my watch. Could it be a VC ebauche? Any comments gratefully received!

VC Ebauche?
I'm not aware of VC supplying ebauches to other brands during that

Yes, but who supplied ebauches to VC?

The watch pictured looks quite JLC-like, in which case I think it could be similar to movements supplied to VC.
At the time most ebauches to VC came from Louis Nardin, Piguet..

JLC came much later and mostly supplied wrist watch movements
The design of the bridges does not look like anything I've seen ...

Borgel Myth

Borgel was a manufacturer of WWI trench watches using supplied movements and I've heard rumours of Borgel wristlets with Vacheron ebauches for some time.  Having asked a couple of Borgel collectors to confirm, they have been unable to locate a single example.  The confusion may be from the fact that Borgel supplied cases to Vacheron rather than the other way around.  To throw in my own two-cents worth, yours doesn't look like a Vacheron and, by that time, they were using six digit serial numbers.
