Adjust A7750 second hand to fit Swiss7750

[kingkitesurf]

Question,

How can one broach the center second hand from an Asian 7750 which is 0,20 to fit the gen swiss 7750 which is 0,25. I want to do a transplant but this is keeping me. The Top Gun second hand gen will be impossible to find. Please advise.

You need two tools:

1.- 0.25 broacher

2.- A tool to fasten teh hand tube.
