One more nit I'll add to this excellent review is a difference I've noticed on the bezel inserts.
- On the 45.5, the numerals are just a hair further from the sliver printed ring than gen. It's most noticeable on the 50 and 20 I think.
- On the 42, and this has been noted in past reviews, the slilver ring is just a bit too thick.
Also, print quality on the reps suffers from lower quality. On my 42, really close up, I can see some minor imperfections that I'm sure the 6K gen doesn't have. Thankfully these are hard to see without a loupe so it doesn't bother my eyes.
Yes + the font thickness is different.
