First time buying a connie pie pan, how to spot if fake or NOT? is this one fake? Thanks in advance for the input...

 

It's genuine but the case is in horrible condition.

PASS.

 

What would you recommend for a starter constellation collection watch?

Welcome @Rbucs
An idea of your budget would help but you’re already on the right track by looking at the round cased Connies if you want an affordable pie pan.
If you haven’t already found this site, try reading this to hone your knowledge:

Look at the how to spot a fake section and also the dial sections.

And you may want to wander over to the ‘vintage omega forum’ to discuss vintage Constellations.
