Question about calibers 1071 & 1072

Hi guys!  I find some troubles when I tried to distingush the two calibers from Vacheron Constantin, 1071 and 1072. In addition to the fact that 1072 can display the date on the right side of the watch whereas 1072 cannot, is it correct to say that the word "automatic" printed on the watch is diffrent between the two calibers?

Here's some images of 1071:  

I find that the "matic" part in the word automatic is kind of in a bold typeface, as you can see the "matic" part isslightly different than other letters in the word "automatic" in terms of typeface.

Here are some images of 1072 in comparison:

Different from 1071, the typeface of each letter in the word "automatic" is identical.Question about calibers 1071 & 1072Question about calibers 1071 & 1072Question about calibers 1071 & 1072Question about calibers 1071 & 1072

 

And again, my question is that, based on the images above, is the difference of typefaces between two calibers commonly exsit in every 1071/ 1072 caliber? Can this difference be used as a standard to identify the two calibers?

Thank you!

I would say these are two separate issues

The differences between the two movements, Cal. 1071 and 1072, cannot be determined by the dial and you have to look at the movements themselves to be 100% sure.  There was a transition period from Cal. 1071 to Cal. 1072 To Cal. 1072/1.  Here are a couple of links to previous discussions about this calibre family:

The difference in fonts from one dial to another is dependent on the different dial makers that VC used.  During this time period, none of the major swiss watch Brands manufactured their own dials and used several suppliers. 

A difference in font within a word is interesting, it could be the original dial maker's work...or it could be a sign of a redial.

Either way, it should not indicate whether a cal. 1071 or a cal. 1072 is inside the watch case.

wring out of a comparison between dials by their graphics is to understand which supplier produced them, although it's not always possible anyway, without watching their backs.

Before this, is important to determine whether the dial has been reprinted, otherwise there's no room left for comparisons.

I'm not sure some of the dials you've posted would pass this test.
