A7750 Reversing wheel needs replacement - ETA will fit?

[GenTLe]

Hi All,

my HBB doesn't autowind and looking in the autowind plate hole where the reverse wheel click is visible, I could see that the problem is in the reversing wheel where the lower gear doesn't "grip" with the upper gear driven by the rotor.

Basically this is the problem:

 

I have 2 questions about this problem:

1) will the ETA gen spare part fit this (recent 28.8kBPH) asian 7750?

2) I remember that once I have already dealt with a similar problem on a 3/6/9 and I ended up having the chrono minute hand not resetting correctly anymore... Is there a way to avoid this? Maybe putting some rodico on the dial to block the hand? I am a bit scared to remove the minute subdial hand because I've already had a case of glued hands on a similar configuration watch...

 

Thanks, GenTLe
