I am looking for a crown for my 14k Seamaster Calendar. Can anyone please tell me the part #/specs (and where I might find one)? I want to see how it runs prior to sourcing a new/needed dial and service.

 

Bowler hat is ok.

 

Would a 42012-y be appropriate/fit the stem?

 

For some reason, those clover crown exist with 2 and 2.5mm opening for the stem, if your watch has the original one it should measure 2.5 though, I believe. Maybe ask the seller about the measurements of his article.

Do you have a picture of the inside of the case back of your example? Knowing the reference would help to answer your question wether a clover style crown is appropriate. The one you're looking at is a modern service replacement, by the way - a period correct one would have a flat foot Omega logo. Not saying you should be bothered by this, your choice, really.

Are you looking for further feedback on the watch or is it just the crown you're looking for?
