What I'm asked about the Omega Museum Collection 5778.71.56
What strap size does the Omega Museum Collection 5778.71.56 take?
The Omega Museum Collection 5778.71.56 needs 24 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Omega Museum Collection 5778.71.56 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.

Yes, in 24 mm leather. On a 40 mm case a calf strap works every day; if you want something more, alligator.

A 24 mm calf strap, for every day. You'll find it ready in the 24 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
