I recently brought an Omega 2367-7 to a watchmaker I'm trying out.

He says he never changed the crown but I remember the crown having straight feet (not with the upward point at the end). I admit a may be paranoid.

If anyone has the same ref. (ending in -7) or a picture of what the crown should look like it would be greatly appreciated.

**EDIT**: I checked the serial number and it's a little later, probably around '49

 

+1 regardless of the -7 or other -x

 

So when did they introduce signed crowns? I'm positive by 47 they had them.

 

..and roughly what years could the crown be from?
