I was wondering what the crown Size would be for my 1960s Omega Seamaster. It's an Automatic 565. Would I need to get the serial number from the back of the case?

 

Hi,

You would need to get the reference number. From that era, it should be a 4 digit number (with probably a variation, such as XXXX/X)
Then you would need to find info on that reference number, that should give you the crown it usually comes with.

 

With a caliber 565 movement it will be a six digit number, something like 166.xxx.

 

Thanks for the feedback. Yes, it's 166.002. Any clue what crown would fit on that? Thanks

Gold one is harder to get.

Awesome - thanks guys. Got a 42052na from ebay.

 

You may want to get a new stem as well. If the current crown on the watch is not original the stem may be to short.

 

Hi guys, I need help. I have a 166.0263 that is missing crown and stem, can anyone suggest me the size and etc. it is in gold plated. Thanks.
