What I'm asked about the Omega Railmaster 220.10.40.20.01.001
What strap size does the Omega Railmaster 220.10.40.20.01.001 take?
The Omega Railmaster 220.10.40.20.01.001 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 Railmaster 220.10.40.20.01.001 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 Railmaster 220.10.40.20.01.001?
Yes, in 20 mm leather. On a 40 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Omega Railmaster 220.10.40.20.01.001?
A 20 mm calf strap, for every day. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
