Good day everyone!

 

Once again, I am in need of your assistance.

I have an Omega cal. 321 in a CK2907 case that was/is not running. Upon first inspection, I found that a broken winding pinion was blocking the movement. While taking the movement apart, I noticed some dirt in the channel where the chrono minute shaft goes. A closer look revealed that the shaft where the stem end rests was damaged, assuming due to the watch falling on the crown at some point?

As a result, the two channels were interconnected, and the residue from the keyless works spread, causing wear on the top of the main plate.

 

Please advise. Is this repairable? What options do I have?

The only solution I can see is to bush it.

definitely would be an option if I would have had proper tooling. 

 

now that Im thinking, the proper question would be, is there anyone from Switzerland who would be willing to help?

First of all, the whole assumption is wrong. The truth is that the holes are interconnected by defoult. Clean and lubricate the movement and enjoy it, no point to wоrry.

If thats true I wonder where did all that bronze come from.

The problem is that the hole is a bit too large, and the shaft has to much shake.

And I supose You believe this will prevent the movement from normal working?

Define “normal”. 
The movement will run just fine. But I believe when I will set the minute hand, it might potentially touch the dial, and thus cause problems.
