Strap for Constellation Co-Axial 38 Day-Date Stainless Steel / Black
Integrated bracelet: measurements, the most common questions, and the way to a made-to-measure strap.
Integrated bracelet
The Omega Constellation 123.10.38.22.01.001 (aka: 12310382201001) is designed with a bracelet integrated into the case. For a compatible made-to-measure strap, the Casati Milano atelier builds it on your watch.

Frequently asked questions
Can a standard strap be fitted to the Omega Constellation 123.10.38.22.01.001?
No, the bracelet is integrated into the case. The lug attachment is not standard, and an ordinary strap will not fit. To change it, I craft something entirely new directly onto the watch, in the atelier.
How does a custom strap work for this Constellation?
I work only at <a href="/pages/casati-booking">Casati Milano</a>, by appointment. I take the watch in hand, measure the case down to every detail — the lugs, the spacing, the height — and shape the strap so it integrates perfectly with the original case geometry.
Which leather do you recommend for the Constellation?
Mississippi Alligator. This Constellation is both sporty and refined — it carries the soul of a chronometer but the bearing of an elegant watch. Alligator resists daily wear well and ages in a controlled way, without losing its character.
How long does a well-made strap last?
It depends on use and care. With thoughtful maintenance — protecting from rain, letting the leather breathe — a good strap lasts 5 to 7 years. The leather develops a patina and tells the story of its time at your wrist.
Why was the Constellation originally conceived as a precision chronometer?
In 1952, Omega designed it to measure time with rigour, not merely to look beautiful. The integrated lugs, the crown with the star — everything speaks of that heritage. A strap that respects this history must be built with the same seriousness.
