Grandpa's watch : genuine? (Omega Genève)

Dear Community,

Please find below my story.

1. What can I tell you?

I just inherited a little watch from my beloved deceased grand-father. I never expected it to be an Omega, hence I was pleasantly surprised to spot the little logo.

As you can see, the dial has suffered a great deal of damage. The "Omega" mark is completely scrapped out, there are a lot of marks, and some indexes are also missing.

Nevertheless it seems to be running pretty smoothly!

There is a signed Omega crown, an indication "Genève", and "Automatic" (almost scrapped out too).
The back side says "Waterproof".
It is around 34mm if my measurement is correct.

I did some research and it looks a lot like a model 166.070, similar to this one :

There is a stainless steel wristband which I'm pretty sure is not original.

2. Is it owned?

Yes, and I intend to keep it.

3. How you can help me?

a) Does the watch appear to be genuine?
b) Would your experience eyes be able to recognise the exact model/year? Is there any way I can determine this without unscrewing the back? (I have no idea how to do this)
c) Are the signs of wear "normal" for a quality watch like an Omega? I would imagine that these are due to over-exposition to water.
d) What would be its approximate value? I'm not considering selling it at all, it's only curiosity.
e) Would it be worth bringing it for review at a watch shop?

I greatly appreciate your help.

Kind regards,

Martin

Hello Wagudc!

Ah that's what happened then..

I do like it a lot. Would it be worth checking Ebay for a replacement dial? I have no idea where to start..

However by changing the dial, wouldn't the watch lose all its history/character? I'm curious to see how much different it would look and feel.
For me, it's first an item to remember my grandfather by, I also wouldn't want to completely change it.

Duly noted for the band 😀

Cheers,
