What I'm asked about the Omega Speedmaster Broad Arrow 321.50.42.50.01.001
What strap size does the Omega Speedmaster Broad Arrow 321.50.42.50.01.001 take?
The Omega Speedmaster Broad Arrow 321.50.42.50.01.001 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 Speedmaster Broad Arrow 321.50.42.50.01.001 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 Speedmaster Broad Arrow 321.50.42.50.01.001?
Yes, in 20 mm leather. On a 42 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Omega Speedmaster Broad Arrow 321.50.42.50.01.001?
A 20 mm box calf. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions
What is the best material for a strap on this rose gold Speedmaster?
Alligator is the most suitable choice: the compact grain enhances the leather without competing with the dial's complexity. Recommended colors are medium brown, deep burgundy, or elegant black. Vegetable-tanned calf leather represents the alternative for those desiring a natural patina that ages over time. For sporty use, gray-black technical rubber guarantees practicality and moisture resistance.
Does an aftermarket strap maintain my Omega's warranty?
Changing the strap does not affect the Omega international warranty on the movement and case. However, if you use a lower-quality aftermarket strap and cause damage to the case (scratches to the lugs), the damage may not be covered. For complete protection, use straps made to professional construction specifications, such as those offered by milanostraps.it.
How long does a leather strap last on a chronograph worn daily?
A quality alligator or calf leather strap, worn an average of 8-10 hours per day, lasts between 3 and 5 years before stitching begins to fail or the leather thins from abrasion. Durability depends on humidity, washing frequency, perspiration, and storage. Rotating among multiple straps extends the life of each. Rubber straps last 5-7 years with regular maintenance.
The next step
The right strap isn't chosen. It is built, together.
