Crown Tube repair

[Dudemeister]

I guess it was inevitable that the crown tube threads would eventually strip on my SMP Chrono. About a year ago I bought one of the newer models from one our member, and while the watch itself was in great condition, the inner threads of the crown tube were weak to start with, and today they finally gave out.

I know I can do the job myself, but I need a bit of guidance from those that have already done this. The watch is the newer version with red Seamaster lettering, if that makes any difference. So here are a few things I'd need pointers on:

1. Replacement part number(s) (I can order from Ofrei as they are just across the bay from me)

2. How is the tube removed (screwed in)? Does it require any special tools?

3. Do I need to replace the tube AND the crown? Which one gets stripped?

Thanks in advance for all the help.

P.S. if anyone has step by step photos or knows of an article like that, it would be of great help

Mine stripped too, so I hope someone knowledgeable will chime in. I've read elsewhere that sometimes it's better simply to replace the movement; I'm considering swapping my high beat A7750 with a genuine one.

swapping the movement will not solve the tube issues....
