What I'm asked about the H. Moser & Cie Pioneer 3804-1201

What strap size does the H. Moser & Cie Pioneer 3804-1201 take?

The H. Moser & Cie Pioneer 3804-1201 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 H. Moser & Cie Pioneer 3804-1201 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 H. Moser & Cie Pioneer 3804-1201?

Yes, in 20 mm leather. On a 43 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the H. Moser & Cie Pioneer 3804-1201?

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