Help identify Omega Seamaster Geneve 166.070 - cleaned dial/redial?

I have a question about a watch I Inherited/ was gifted from the the widow of a dear customer of mine. He recently passed away with 91. In the the last years he used to wear this Omega Geneve/Seamaster a lot.

He Used to wear it on a nato strap. And we often talked about his watches. And his wife said he wanted me to have it so she passed it on to me.

Today I received it and got to take a closer look at it. I noticed that the hands have been relumed. And it seems the second hand was also replaced at some point.
I also noticed that there is parts on the dial that are dirty (f.e. around the 12 hour marker). Around the date window is also black residue. And part of the seamaster lettering is gone. It seems to me that the dial could have been cleaned at some point during its long life. And while cleaning the seamaster lettering was damaged.

The other possibility is that this lettering has been added later on since I couldn’t find any other example of this kind of double named Seamaster Geneve where the word seamaster is placed below automatic and not above Geneve. But I didnt research a lot of time.

Or am I wrong and was there a omega model where it was placed on the dial like that? Was there a model and time where it was done like that?

The plexi chrystal is original/at least it is omega signed. And the crown is omega signed as well.

To identify the model reference I will have to visit my watchmaker next week to open the watch for me. So I can then look at the reference number inscribed on the caseback.

Can someone may be give me a hint on what kind of reference this could be?

With such a possible ref. Number I can do more research before I visit the watchmaker (I won’t be able to visit him before end of next week)…

Furthermore I am interested to speculate about the calibre it might use. The date changes with a quickset feature:
If the crown is pulled outwards the date jumps one day ahead. What kind of calibres was this features used on?


And yes the buckle on the leather strap is a poorly made aftermarket buckle 🥴😉

Kind regards and thanks upfront for any help, inside and input!

And for anyone wondering I am just looking for input and will definitely keep this piece in honor of the previous owner. I am really honored that he wanted me to have his most worn and most cherished watch. 😎😉

A very nice gesture that it was given to you,
dial looks original to me but unfortunately the Seamaster writing has been added on later for some reason and isn’t correct
It’s called an omega Geneve
Entry level omega but still a very good watch with a good movement
Possibly a 565 movement cal with a case ref of 166.070

hi Wat-1

Thanks for giving me possibly reference. The case of 166.070 geneve models indeed look pretty similar.
I will look into that 565 movement specs.

And yeah the seamaster inscription seems so off and wrong. So you support the impression invalid had that it was added later on. For what ever reason someone might have to do this…

Geneve models were positioned as the more affordable in Omega's lineups, its likely 'Seamaster' was added at some point to help boost its perception.

Sounds like a reasonable explanation. That decreases its appeal from a collector view. But that doesn’t matter in my case since it was such a nice gesture and a gift.

It still funny what they back in the day do to those pieces…
