Hi there,

I might be mistaken, but afaik the champion models are not genuine, but were made in license by a different manufacturers, when Heuer was about to go bankrupt.

At least that's what I've been told.

Matter of fact, you can still buy NOS Heuer champion dials from certain dealers, fitting cases, movements etc. and make one by yourself ; they pop up on Ebay frequently and sell for silly money (I bought one....) .

That said, I doubt there is any particular watch strap made for thes watches.

Best
