Tudor ETA 2447 Stem???

[mzinski]

I have a Tudor ETA 2447 with a broken stem. I cannot for the life of me find any information on the ETA 2447 nor what alternate Calibre may have a compatible stem. 
Can anyone help me determine what stem would be compatible? 
THA!

Can you show us pictures of the movement? It may stir up the old grey cells somewhere.

So far I only turned up this. -> http://cgi.julesborel.com/cgi-bin/matcgi2?ref=ETA_2447

.. but that spring fits the following -> http://cgi.julesborel.com/cgi-bin/matcgi2?ref=q}B~UVE

.. so that may or may not be of help.

It may be related to the ETA 2442

Thanks, I found that relationship at Jules Borel too. 
 

Here’s a pic of the movement:

That looks pretty similar to the ETA 2450, 2451, 2452 etc.

What size is it?

Don’t have it in hand to measure at the moment. But I did find this, I think it’s 7.75 ligne (fits in a 23mm case).

That windinstems.com link looks likely to be correct.

... also this ebay link ...

... which states the following ...

Thanks for talking through this with me. It’s funny I search ETA 2447 all over but it wasn’t until I search “ETA 2447 diameter” that info about the stem appeared. 
I’ve ordered a 2360 stem - hopefully problem solved. 

[AndyHull]

I'm 99% certain it will work. Keep us posted with progress.

The 2360 fits perfectly!
