What I'm asked about the Arnold & Son Royal Collection 1TBAS.B01A.C113S

What strap size does the Arnold & Son Royal Collection 1TBAS.B01A.C113S take?

The Arnold & Son Royal Collection 1TBAS.B01A.C113S 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 Arnold & Son Royal Collection 1TBAS.B01A.C113S 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 Arnold & Son Royal Collection 1TBAS.B01A.C113S?

Yes, in 20 mm leather. On a 46 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Arnold & Son Royal Collection 1TBAS.B01A.C113S?

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.
