You are correct Michwr - there is an early Monaco dial style and a late one! It is true for both blue and grey dials.
For me it is not to U-RON or not to U-RON, but rather the case of the Fat RA and the Normal RA....
To check your theory, I looked at the blue transitional Monaco dials. I used the OntheDash Chronograph Galleries, which are a fantastic reference resource. I have taken blown up versions of these photos to emphasize the point.
If we look at the Blue Transitional style, which we know was earlier than the “normal” 1133B blue dial, you can clearly see the different font on the dial. I think the line-up of the U and O is tricky to see (you need a head on shot ideally), but you can really see a weird “fat” RA in the word “CHRONOGRAPH”. In particular the A has a flat top rather than a pointed top:
You can see this font in all the blue Transitional dial Monaco’s - here is another photo with a different watch (also from the gallery):
It’s really easy to tell an early blue dial from a late, as the really early ones for the Transitional have a metallic finish. But you can also see this change in font, as the later matte blue dials have a “normal” RA with a pointed A:
But what is new that Michwr noticed is that you can also distinguish early and late grey metallic dials with sunken subdials! We already knew that the black “flat” subdials versions of the 1133G are later dials, but we didn’t know there were two varieties of the early grey sunken subdial version of the dial.
Here is the early grey sunken subdial version of the dial with the characteristic “fat” RA and the flat top A:
Then you can see the dial change to the later font with the “normal” RA and pointed A, with the same change in font seen in the move from shiny transitional to flat blue in the 1133B. Here is a later grey sunken subdials version of the dial:
The sunken subdial 1133G I have seen was with the later style of dial (pointed A) and with a 16xxxx serial.
Hope it is useful for people
PS: My dream has been to find a “transitional” 1133G with the rectangular hands, now we know it would need to have a “fat RA” dial to be correct! And then the grail of grails, a grey Chronomatic....that really would be a find.
