What I'm asked about the Omega Railmaster 2804.52.37
What strap size does the Omega Railmaster 2804.52.37 take?
The Omega Railmaster 2804.52.37 needs 19 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Omega Railmaster 2804.52.37 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 2804.52.37?
Yes, in 19 mm leather. On a 36 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Omega Railmaster 2804.52.37?
A 19 mm calf strap, for every day. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
