What I'm asked about the Omega Constellation 123.10.35.20.01.001

What strap size does the Omega Constellation 123.10.35.20.01.001 take?

The Omega Constellation 123.10.35.20.01.001 needs 16 mm between the lugs, usually 14 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Omega Constellation 123.10.35.20.01.001 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 Constellation 123.10.35.20.01.001?

Yes, in 16 mm leather. On a 35 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Omega Constellation 123.10.35.20.01.001?

A 16 mm calf strap, for every day. You'll find it ready in the 16 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
