Seamaster DeVille reference number?

[GerardCardinal]

Hi, I own this watch and therefore _could_ take it to a watchmaker. But all I’m after is the reference number. It is a Seamaster DeVille so it opens through the crystal. This is beyond my skills.

This is what I know about it:
Seamaster monocoque 34 mm case
14k gold bezel/stainless back
565 caliber
Mid 60’s.

As I say, I could definitely take it and get it opened, but if someone could know the reference by the information and picture I provide, that would be super.

thank you in advance,
Gerard

Came to say this. I have a 166.020 although the dial on this one is very nice!
It will be gold cap over stainless steel case.
