1960's Seamaster De Ville for my wife - What movement?

Good day, Omega Fans,

This is post 4 of 4. Today, I'm illustrating my final vintage purchase, an Omega Seamaster De Ville I got for my wife! BUT secretly I love it and plan to wear it as a dress watch.

What movement comes in this watch?
Is the crown correct?

I welcome all/any feedback you have on this one.

Check out my previous posts, as I would love you see your comments on my three (3) other purchases:

I really appreciate all the help thus far...

I say this with all due respect...

Were you born stupid or did you have a recent traumatic brain injury?

Get your own!

Goofball. 😀

A combination of the two! I picked up 4 SM in one transaction, so I need to cool the jets and start investing in servicing.

For sure... no contest!

Strapped and Serviced. Turned out really nice!
