Strap for Constellation Quartz 24 Polished Yellow Gold / Champagne Supernova

No. The bracelet is integrated into the case—there's no spring bar system. Strap and case form a single structure. A standard strap won't attach. In the atelier, I build the piece bespoke, fitted to the geometry of your watch.

We work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from your case, studying the lug angles and how it sits on your wrist. Every millimetre is shaped by hand to integrate with the yellow gold as though it were born together.

I prefer Mississippi Alligator or Barenia in tone-on-tone with the yellow gold. This Constellation has refined, understated character—it deserves leather that ages with dignity, developing natural patina. Mississippi alligator has subtle grain; Barenia carries a lived-in soul.

With care, 5–7 years of daily wear. The leather breathes, develops patina, settles into your wrist. Just avoid prolonged moisture and occasionally condition it with neutral cream. Barenia especially ages beautifully: every scratch becomes part of its story.

The four lugs embracing the sapphire crystal are pure architecture—born in 1952 and still unmistakable today. It's measured elegance, never shouted. A watch that speaks to your wrist, not the room. On this model, the integrated bracelet amplifies that coherence of design.
