They're fairly common, and go for around $5k. I paid $4k for mine brand new 12 years ago, and the current 2026 models go for around $7k (Inflation and Omega has raised their prices quite a few times as they've gotten more popular and positioned themselves better in the market).
The trick is finding one from that era in decent condition, good patina, original dial/hands/bezel/bracelet, etc.
