What I'm asked about the Certina DS First C0142173305100

What strap size does the Certina DS First C0142173305100 take?

The Certina DS First C0142173305100 needs 17 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Certina DS First C0142173305100 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 Certina DS First C0142173305100?

Yes, in 17 mm leather. On a 35 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Certina DS First C0142173305100?

A 17 mm box calf. I don't keep this size ready in the catalogue: I make it to measure. If you'd rather have something built on your wrist, the Casati atelier.
