What length do I need?
Measure your wrist with a tailor's tape or a piece of string, comfortably snug.

| 16.5–17.8 cm | 115 / 75 mm |
| 17.9–19.0 cm | 120 / 80 mm |

The ready-to-wear strap is 115 × 75 mm. For a smaller or larger wrist I make it in the right length: order your length.
What I'm asked about the Omega Dynamic 5290.50.27
What strap size does the Omega Dynamic 5290.50.27 take?
The Omega Dynamic 5290.50.27 needs 20 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Omega Dynamic 5290.50.27 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 Dynamic 5290.50.27?
Yes, in 20 mm leather. On a 38 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Omega Dynamic 5290.50.27?
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.
