I don't like to comment on cropped photos because important clues may have been omitted, but I will go so far as to say the dial closely resembles several V&C models with central and sub-seconds from 1936 - 1938, such as photo ref 3800.
The movement is most surprising as I've never seen that modification for center seconds from V&C. The base resembles a 9-ligne caliber 458:
Now the 458 was itself was given central seconds with the caliber 466, but this aint that!
There is a crude friction spring for the central jewel which is unneccesary with that bridge placed over the second and third driving wheel. Since the spring is there, I question the purpose of the center pivot jewel on that bridge? The layout just doesn't make sense to me :-( What is the history of this watch, do you suspect this was a modification from some time in the past or a recent fabrication?
This is how the friction spring should function to secure the center pivot jewel, here on the cal. 1002:
The dial is rather thickly painted and, if this piece was modified from sub-seconds, the original dial would have to have been replaced or modified and repainted. Many other thoughts cross my mind but I will refrain until you can share complete pictures with us.
The 30s was a wild and difficult time for the Manufacture and many old movements were cased-up for a quick sale. Your movement number is quite a bit earlier, late 1920s, and the case number mid-1930s, so the info you receive from VC's Heritage Department may be informative but, even if the numbers match up, they may need to examine it directly to confirm authenticity.
