Strap for Constellation Co-Axial 38 Yellow Gold / Diamond / Silver

No, the bracelet is integrated into the case and the attachment system is proprietary to Omega: a standard strap won't fit. For this model I craft everything by hand at the atelier, taking measurements directly from your case and creating a bespoke attachment that works with the yellow gold without compromising the original proportions.

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements and thickness readings directly from your case, study the integrated attachment architecture, and handcraft the strap in my atelier. It's the only way to achieve a proper fit that honours the original design.

I favour Mississippi Alligator dyed in honey tones: it complements the warmth of the gold without competing for attention, and the sporty elegance of this watch calls for leather that ages with dignity. Natural Barenia is another choice if you want to see it evolve toward deep amber tones over time.

It depends on wear and care. Good leather, built with appropriate thickness and proper stitching, will perform for 5–8 years of daily use. Then the skin thins, the patina deepens. With occasional cleaning and letting the strap breathe, it lasts even longer. It's not a short lifespan—it's a relationship that evolves.

Omega designed this architecture in 1952 as a statement of precision and structural integrity: the bracelet integrated into the case reinforces rigidity and creates a visual harmony that a detachable strap cannot match. It was a technical and aesthetic choice together, and it demands respect when you transition it to a leather strap.
