Omega 166.037 Too Good?

I am looking to buy my first Omega. Currently looking at 60s/70s Seamasters and Geneves. I came across this 166.037 and I am concerned that it is potentially a redial.

1. All the other examples I see of this reference are Seamasters.

2. I have never seen this dial in all my searches.

3. It seems too nice

So any help is appreciated!
