Measure your wrist with a tailor's tape or a piece of string, comfortably snug.

The ready-to-wear strap is 115 × 75 mm. For a smaller or larger wrist I make it in the right length: order your length.

What I'm asked about the Omega Speedmaster Moonwatch CK2915

What strap size does the Omega Speedmaster Moonwatch CK2915 take?

The Omega Speedmaster Moonwatch CK2915 needs 19 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 Moonwatch CK2915 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 Moonwatch CK2915?

Yes, in 19 mm leather. On a 39 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Omega Speedmaster Moonwatch CK2915?

A 19 mm box calf. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
