What I'm asked about the Fortis Novonaut F2040013
What strap size does the Fortis Novonaut F2040013 take?
The Fortis Novonaut F2040013 needs 22 mm between the lugs, usually 18 or 20 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Fortis Novonaut F2040013 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 Fortis Novonaut F2040013?
Yes, in 22 mm leather. On a 42 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Fortis Novonaut F2040013?
A 22 mm calf strap, for every day. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
