Nice work mate, I presume you mixed some hands about?, looks super:) I'm still confused about these cases though... My STAILESS steel 16** doesn't have that ring machined around the top of case. (has exactly the same serial no)
The plates cover the movement holding screws so it's not possible to get the movement out without removing The plates, but they are just stuck on, you have to pull them off carefully . (on mine anyway it's just a regular a6497 ) Alas, you're picture indicates a different movement, I dont know... :lol:
I swapped the subdial hands on my build, I remember ordering so many different sets...the ones that fit were 0.26mm. I'll have a look see if i have a spare set on my bench.
