I have a milestone birthday coming up and have just begun the recon mission on finding a piece that will complement, but not directly compete with anything I currently have. Not into overly dressy or rectangular watches. 39-43mm range under $10k. No Rolex, I've had a few and I didn't like the attention they got. Any suggestions would be greatly appreciated!
I would go for an IWC Pilots Chronograph (Green or Petit Prince), JLC Polaris. Scratch that. You should definitely get a Zenith El Primero before any of those.
All three here are stellar recommendations!
