I have an opportunity to buy a Vacheron Constatin reference 33051, made around the early 1970s with the respectale Calibre 1003/1. In looking through the www, I noticed there are small differences in the way this reference looks in pictures. All the pictures on the internet are with the same reference number (33051) and same Calibre (1003/1), but I noticed that the hands are longer on some and shorter on others; and the VC cross logo (?) is very close to the "12" marker in some while farther away in others. The "Vacheron Constantin" fonts are a little different in some pictures, too.
Am I looking at some replicas, or Re-dials, or variation in dial design from different years?
Below are pictures of the watch that I'm potentially buying, and below that are various pictures from the internet.
And, now, below are various, random pictures of the same reference pulled from the internet. Please notice that the watches in these pictures have hands that are slightly shorter and, in particular, the VC cross logo (?) are much closer to the "12" marker. The font is slightly different, too.
And, yet, other random photos of the same reference shows the watch to have the same hands and VC cross placement as the one I'm hoping to buy. Please compare these to the photos of the watch I'm considering (first set of pics above):
Please help. Am I looking at fakes, re-dials, or variations in design through different years? Should I buy, or sit out?
