My watch's crown came off, can anyone tell me which parts are needed to fix it? Thanks.

 

This is a split stem design - it's meant to come apart, and if you carefully liner up the stem, parts, you can likely snap it back together.

 

I can snap it back. But it came off again when i pull it out to set the time.

 

Then you need to take it to a watchmaker...

 

I took it to watchmakers and they don’t have the parts. So I am trying to find the parts in internet.

 

What exactly did your watchmaker say they don't have? The crown looks fine, so you either need a new male split stem or it is being installed wrong.

 

They said the “stem” was corroded and needed replacement. But they don’t have the part.

 

You could try a different watchmaker - any watchmaker with an Omega parts account can order the needed parts.

 

Is that a cosmic case that doesn't open from back?

If it's corroded I guess stem replacement is the only solution, but if it's not corrosion, you can always squeeze the crown's holding part just a tiny bit?

 

Yes, its a cosmic case. One watchmaker suggest replacing it with a one-stem part. I doubt it works or not.

I think he needs a male stem, but that watchmaker is definitely loco, one piece stem is a no-no

 

Very bad idea if he is suggesting a one piece stem...

 

He would discover that quickly when trying to put it back together.

 

I think he's just going to push and lock the stem inside, if it's the push-button type maybe with enough force it locks in there, the next watchmaker can figure out how to remove it

 

Yes, much easier to install than remove...I wish I could say I’d never seen this, but I can’t...

 

I doubt the part inside the watch is corroded. If it was. There would be some evidence on the female part on the crown

When you tried to place the crown back on. Did it go all the way in (bottom of crown flush with case?)

Watchmaker needs to remove the movement and get the case reference number + caliber number

Don't need an Omega parts account for certain pieces. Just email a parts supplier and see if they have in stock

Otto Frei, Jules Borel, Cousins or H W Perrin

A check of a caliber of the same period shows either a narrow beak or a wide beak for the male part.

Could just be. You have the wrong male part and you need the wide beak

Or. Just as someone mention. Could be some wear and squeeze the crown part closed a little bit more

Just don't take it back to this guy.
