The detail from FF this time is very useful for me and I am certain now to go for the 2 mm thick of crown. All the PAM I have, the crowns are 2 mm but they look thin. Now in the photos of FF, we can see clearly that the gap between crown and CG is too large of Rep compares to Gen.
I plan to mod the CG to reduce this gap and see how it looks. If I can do it sucessfully, I will try to post it in RWI here so we can see the result. I think to mod the CG, the filer will not work. I will put it on the CNC milling machine and will thinner the CG just for like 0,3 to 0,5 mm. I am also very exciting of this mod. If it is successfully done, my PAM will look much better. Let see.
Thanks again FF for your greatful information. Very much appreciate for your great job on these watches.
