Frequently asked questions
Can I fit a standard strap onto the Omega Constellation 123.20.38.21.06.002?
No, the bracelet is integrated directly into the case — there's no lug for standard straps. I've seen clients try quick fixes: they don't work. The only way is to have a bespoke strap made in the atelier, tailored to your specific case geometry.
How does the bespoke strap process work for this Constellation?
I work only at <a href="/pages/casati-booking">Casati Milano</a>, by appointment. I take measurements directly from your case — the attachment points, width, angles. Every detail is calibrated by hand because no two cases are identical, even within the same series.
Which leather do you recommend for this model?
I prefer Mississippi Alligator with large scales or extra-soft French Barenia. The Constellation is elegant but has broad shoulders and a sporty character beneath the red gold — the leather must breathe and age with dignity, not suffocate. Alligator develops a splendid patina over years.
How long does a well-made strap last?
A properly maintained strap lasts 6–8 years, sometimes longer. It depends on use: if you remove it every evening, it lasts longer. Good leather ages visibly — it deepens in colour, gains character. It's not wear, it's transformation.
Why does the Constellation have those 'griffes' on the case?
The griffes were born in 1952 as an aesthetic signature: they embrace and protect the crystal. It's not just form — it's architecture. That's why the strap must dialogue with that geometry, not fight it. In the atelier I model every curve to respect that original vision.
The next step
