I am not certain on thickness measurements, so I couldnt say what they were..
I have noticed however that dial thickness' did vary on the gens I have had..not by much and only to my eye so again its a subjective opinion...
Though looking at say what D did in his post I would say these are thinner regardless of the lume though with changing this you can negate the shallow rep look but wont acheive the full gen look...
I think a lot of what you see on the gen isnt just the plate itself but also the build up on it of the base coat, top coat and lacquer...which the rep dials dont get or certainly dont appear to get...
What I havent paid attention too and will do at the next opportunity is compare the dial feet and base plate thickness as this will also provide more information on the comparison of gen to rep relative to the way the CP and hands sit above the top plate.
I dont think anything is going to change on this dial as when I spoke to Angus he said the only variation from this to the final dial being used on the 312 was the GMT... so given that the 312 is the final version its logical to assume this is the final GMT dial...
I really dont think we are going to see much difference in any of these models now... the only outstanding part that I have been told is still not final is the shape of the CG lever but I think reading between the lines this doesnt inclue the distance of the lever from the case, which is another shame..
On another small point..none of these models will have SL.. it will be a decent lume but not gen standard
Having said all that I still think this whole process has been a great example of how things could be progressed in developing reps.... if only !!
These are still going to be nice reps compared to whats currently available... and until the movements are sorted the main flaw, the position and size of the DW, will always be evident so what harm does a few other flaws do overall !! ;)
