What I'm asked about the TAG Heuer Formula 1 CAH1012.BT0717

What strap size does the TAG Heuer Formula 1 CAH1012.BT0717 take?

The TAG Heuer Formula 1 CAH1012.BT0717 needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the TAG Heuer Formula 1 CAH1012.BT0717 be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Can I put a leather strap on the TAG Heuer Formula 1 CAH1012.BT0717?

Yes, in 20 mm leather. On a 44 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the TAG Heuer Formula 1 CAH1012.BT0717?

A 20 mm box calf. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
