Are you in a position to let them down gently, because I'm afraid it's not.

That's not a Camaro case. The dial's not a Camaro dial, nor I think is it a Heuer dial from another model - as far as I can recall, Heuer didn't use that style of stamped register at all but instead properly bevelled and recessed ones. You'll note that all the hands are somewhat too long for the dial too, so they have come from somewhere else.

Looks like a collection of parts from a number of donors brought together and given the Camaro name, presumably because of the cushion case. I'm not seeing any Heuer parts at first glance - the pushers and crown could be, but the crown looks a bit too thick for the case anyway.
