What is this vintage omega?

[random.collector]

Good Morning,
I bought this about 6 months ago randomly for $400. Figured it maybe redialed - but I loved it. Plus my fiancé has worn it for months. Figured vintage, automatic, omega, $400… why not.

It runs. I haven’t opened it yet. Going to do that soon and update photos then.
Back of the case has “p2516” engraved it - anyone know what that is? Or what this watch is?
Thanks so much for the help.

Also - Tanner Moorehouse just finished up my 1970 Mark 2 you all helped me with. Should be getting that back in the next week or so! Will update that as well!

you guys are awesome! Happy hunting and collecting!

A Google lens search shows that it looks like a 162.045. Most of them have DeVille or Seamaster on the dial, though, so you might be right about it being redialed. The dashes around Swiss Made would usually indicate tritium lume, which I don't see, but as I understand it, this is not a hard and fast rule.

Just on the dashes, they don’t indicate tritium lume. Around the late 60’s/early 70’s the dashes appeared for a short while, some with T’s, some without, but the dashes on their own don’t indicate tritium

Thank you. I appreciate the clarification.

Somebody just engraved the P2516 on the back. Not factory.

this is not true - Tritium is indicated by one or two "T"(s) not by dashes

Your watch has the dial style and case design that was popular in the early 1970s, similar to the DeVille product line shown in this catalog image from 1972:

Yeah, I definitely misunderstood. Apologies to the OP for any confusion.
