Frequently asked questions

Can a standard strap be fitted to the Omega Constellation 1372.70.00?

No, the bracelet is integrated into the case: there are no standard lugs. The architecture is conceived as one piece. To change it, you need bespoke handcrafted work, directly on the case.

How does a bespoke strap work for this model?

I work at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I bring the watch in hand, study the original griffes and measure everything directly from the case. I craft a bespoke attachment that respects the model's unique geometry.

Which leather do you recommend for the Constellation 1372.70.00?

I prefer Mississippi Alligator in mother-of-pearl tones, or soft champagne Swift if you love suppleness. This model is feminine and refined: the leather must dialogue with yellow gold without competing. Alligator ages beautifully, developing patina over time.

How long does a well-made strap last?

With daily wear and proper care, expect 5-7 years of conscious use. Quality leather ages, it doesn't die: it darkens, breathes, tells the story of your wrist. With care—a light balm application now and then—it lasts even longer.

Why is the integrated bracelet so complex to modify?

The griffes embrace the case like architecture: they aren't simple lugs. Studying them, translating them into a new strap, maintaining the elegant line that defines the Constellation—requires hours of handwork. It's not a modification, it's a rewriting of the detail.

The next step

The right strap isn't chosen. It is built, together.
