What I'm asked about the Omega Speedmaster Dark Side of the Moon 311.92.44.51.01.006
What strap size does the Omega Speedmaster Dark Side of the Moon 311.92.44.51.01.006 take?
The Omega Speedmaster Dark Side of the Moon 311.92.44.51.01.006 needs 21 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Omega Speedmaster Dark Side of the Moon 311.92.44.51.01.006 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 Dark Side of the Moon 311.92.44.51.01.006?
Yes, in 21 mm leather. On a 44 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Omega Speedmaster Dark Side of the Moon 311.92.44.51.01.006?
A 21 mm box calf. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
