Nice work, all.
TMG - I really like what you have done with your 1675, but I think you need to 'antique' it a bit. As it is, the watch looks too pristine, which, for this model, is not a benefit. If you gave it the 'Nanuq treatment' (a few minutes of accelerated motion (shaking) within a jar filled with coinage), it would just about have fooled me (even with the over enthusiastically countersunk lug holes).
Something I just noticed -- Definitely, a VERY small detail, but I thought I would mention it -- The division between red & blue at the 18 in the bezel insert may not be at the right spot. I think division on the gen insert occurs right in the middle of the number & yours is just prior to the 8. One of the parts sellers has better inserts for this model, but I cannot remember who it was?
