Can anyone identify this vintage Vacheron Constantin?

Hello all,

I am looking for some information about my grandfathers watch. I believe the watch is from the early sixties and was serviced about two decades ago. Any help would be great, thank you!

The reference number should be marked on the inside of the case back.
From the photos, I can't tell for sure if the case is yellow or white gold.

Thanks for your reply, I belive the watch is cased in either white gold or platinum. I do not have the watch in my possession otherwise I would've checked the caseback.
