What I'm asked about the Omega Speedmaster First Omega in Space 311.63.40.30.02.001

What strap size does the Omega Speedmaster First Omega in Space 311.63.40.30.02.001 take?

The Omega Speedmaster First Omega in Space 311.63.40.30.02.001 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 First Omega in Space 311.63.40.30.02.001 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 First Omega in Space 311.63.40.30.02.001?

Yes, in 20 mm leather. On a 40 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Omega Speedmaster First Omega in Space 311.63.40.30.02.001?

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.
