What I'm asked about the H. Moser & Cie Pioneer Cylindrical Tourbillon 3811-1203
What strap size does the H. Moser & Cie Pioneer Cylindrical Tourbillon 3811-1203 take?
The H. Moser & Cie Pioneer Cylindrical Tourbillon 3811-1203 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 H. Moser & Cie Pioneer Cylindrical Tourbillon 3811-1203 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 Cylindrical Tourbillon 3811-1203?
Yes, in 22 mm leather. On a 42.8 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 Cylindrical Tourbillon 3811-1203?
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.
