Hi!
Can someone please inform me on the measurements needed for sourcing a clover crown that fits the 2757 Seamaster cal. 355?
Thanks!

 

Here is what https://www.cousinsuk.com suggest and they seems to be in stock.

 

Thanks so much! Cousin's search function is really good, I was looking at Ofrei and it's a lot more difficult to find things there. I have found a nice Seamaster with a generic Omega crown, but the clover crown really makes a difference on this model.
