Hi there, looking to find a 9220n. This is a black dial camaro with 45min register without tachymeter. 9220nt and 7743n models seem quite common, but so far I've only seen one 9220n for sale at a Bonhams auction last year.

Here's a link to it on the Heuer Camaro page:

Let me know if you see one!

Cheers.

 

You're right, there's really not many of them compared to the other 9220s. I'll keep an eye out though.
Best, Steve
