What I'm asked about the Omega Speedmaster '57 331.10.42.51.01.002

What strap size does the Omega Speedmaster '57 331.10.42.51.01.002 take?

The Omega Speedmaster '57 331.10.42.51.01.002 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 Omega Speedmaster '57 331.10.42.51.01.002 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 Omega Speedmaster '57 331.10.42.51.01.002?

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 Omega Speedmaster '57 331.10.42.51.01.002?

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.
