Does anyone have the exact measures of the correct tube (outer and inner) measures of the crown tube inside the case and also of a correct flat feet crown?

I'm a little bit confused because the mounted service crown fits the tube but the flat feet cown not.

Thanks

 

Are you sure the flat feet originally came from a Speedmaster?

 

No but the outer measures are OK (6,7)...

Thanks, I've seen this thread but my problem is the tube outer diameter (case side)...

 

If a correct replacement crown fits the case tube, and your other crown does not, it's not the case tube that's the problem...

Sometimes they don’t fit because the inner gasket has melted or because the inside is filled with gunk...
Maybe it is not a Speedmaster crown but a Seamaster or Railmaster crown.

 

Yes, agree. I would like to figure this out so we can all participate...

 

What is the OD of the case tube on the watch you have?

Note sure there is too much to figure out here - likely the wrong crown.
