Telux / TAG Heuer 80s F1 Connection?

Just saw this on eBay and thought it was a Formula 1 right off the bat... the strap is identical but with different text to the 80s F1, the case, bezel even hands are about identical to the original release TAG Heuer Formula 1 that I bought for my youngest nephew, even the TAG Heuer shield logo is still on the strap just with different branding.

That F1 is probably close enough to be a source of spare bezels, I just figured given the strap even has the exact shape it might have been some shared production, I mean who'd "borrow" the strap right down to the TAG Heuer shield unless they were incredibly lazy but what you said makes sense. I'm still trying to figure out what the weird numbers are on the outer edge of the F1... can't think of what they relate to
