What I'm asked about the Steinhart NAV.B-CHRONO NAV.B-CHRONO 42 CLASSIC A-TYPE

What strap size does the Steinhart NAV.B-CHRONO NAV.B-CHRONO 42 CLASSIC A-TYPE take?

The Steinhart NAV.B-CHRONO NAV.B-CHRONO 42 CLASSIC A-TYPE 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 Steinhart NAV.B-CHRONO NAV.B-CHRONO 42 CLASSIC A-TYPE 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 Steinhart NAV.B-CHRONO NAV.B-CHRONO 42 CLASSIC A-TYPE?

Yes, in 20 mm leather. On a 42 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Steinhart NAV.B-CHRONO NAV.B-CHRONO 42 CLASSIC A-TYPE?

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.
