I understand what you are talking about. In fact, the old and the new case have differences in the shape of the bezel and crystal, it's true.
I also, it is not much, due to the transparent caseback on 441/438, but this difference is taken into account.
The difference remains in the thickness of the midcase and the measurements of the
jonnybaws show this. The thickness should be similar to 1312 according to my logic.
Considering that the design of the 1950 ceramic case is such that the bezel is screwed, as on vintage radiomirs, as an example, they can put a new bezel with a crystal and reduce the thickness.
But changing the midcase to a new one, given that the shape of the lugs has not changed (they became thinner on the steel and titanium 1950s), I think they will not.
But we won't get 3mm. At best, 1-1.5, but that will be much better.
Photo comparison midcase:
(As you can see, the difference from gen is also in 1312, but relative to reps with each other, it is not great, and you can live with it)
Photo of the bezel construction:
(As you can see from the photo provided by
Repworld in thread 441 it is threaded, and you can replace it with another design, correct for the new ceramic 1950 44mm)
Photo of the difference in the shape of the bezel:
(This is gens for example 441 and 438 in relation to 1441 and 1438)
