Thank you for taking the time to stop by our forum! I think it a nice gesture to ask the members for ideas, very similar to what Doxa has been doing recently..I was a Doxaholic for a brief period..
As to suggestions, I personally would love to see a PVD monaco. Of all the Heuer that I have owned, it is one of the few that I have kept....second watch I would like to see is the Autavia but with a GMT function, and the red/blue bezel...again another one that I have kept.
Lastly, the mareographe sounds like a great idea...what case shape do you propose, Carrera or Autavia?
The 2447CSF is the one vintage Heuer that my wife wears, would love to see a picture of yours.
Cheers,
David
