First Omega Seamaster Cosmic

diegova88 · Aug 7, 2025

Hey everyone,

Recently bought my first Seamaster Cosmic 135.017 Silver dial crosshair.
Love to hear if I made a good purchase or not.
I’m new in the vintage world so all the information I can get will be highly appreciated!

That all depends. At $10 USD it’s a great purchase, at $2000 USD not so much.

Paid 600€ for it. I’m trying to learn as much as possible on what to check/pay attention to in terms of state and authenticity.
