OK, I have it roughed together and I've decided I'll probably have to machine some sort of spacer to thread into the case and then thread a shortened tube and crown into that. The spacer will be painted red so hopefully it will get the general look. I had to order an M3 x .35 thread die so it will be a little while before it is finished. This will be Rev. 1 of the project and some day when there are more good straight-on large pics of the gen, if it hasn't been repped, I'll re-do the dial artwork with the Tudor the correct size and font. But, for right now I'm fairly happy with the looks and I think I've captured the "essence" of the gen...
Here's a couple shots of the test fitting. The tube is not finished and the stem has been left long on purpose to leave some for final fitting...
The "blush" didn't dry out of the clear so I guess I'm stuck with it but it has a nice "vintage" feel. On the close-up I see that I didn't get my decal perfectly centered but it's not too apparent on ther wrist:
The T21 presents a profile very close to the one on the gen so I'm pretty happy with that:
I'm not sure what the clasp on the gen looks like but I figured this would be a nice touch:
