I spotted some Heuer branded cases on Watchco's Ebay auctions today, and wondered whether anyone (especially Jeff) might have a clue what models they derive from.

They can be found here

from what I can see, Heuer never made a chronograph using this case, but Sinn did, and various others offered them. the relevant Sinn model was the 143, seen here

I recall that Chuck had a "mistral" branded one, and I have seen an "Arena" one too, but never a Heuer.

In considering a pd put-together, Chuck published photos of the Mistral here

Any clues??
