The Constellation 1186.75.00, seen from the bench

The Constellation represents one of Omega's historic collections, characterized by the distinctive design with the crown integrated into the case profile. Reference 1186.75.00 mounts the Omega 1376 quartz caliber with hours and minutes indication. The model maintains the classic proportions of the Constellation line with a precious metal finish.

Frequently asked questions

Can a standard strap be fitted to the Omega Constellation 1186.75.00?

No, the bracelet is integrated directly into the case: there is no standard lug attachment for a strap. I've seen many people surprised by this, because the red gold immediately suggests the desire to change it. But here I build everything bespoke, directly on the watch, without forcing anything.

How does the bespoke strap process work for this model?

We work exclusively at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take the watch in hand, measure the case in detail, and build the strap honouring that geometry. It's not quick work, but it's the only serious approach for a Constellation.

What leather do you recommend for the red gold Constellation?

I prefer Mississippi Alligator in Cognac tone. Red gold has a warmth that calls for equally mature and deep leather. Cognac speaks with the metal without competing, and alligator ages in exactly the character of this watch—richer every year, never fragile.

How long does a well-made strap last?

With care, 5–7 years of daily wear without issue. Leather ages—colour shifts, patina develops—but this is beauty, not deterioration. I recommend cleaning the strap every two months with a damp cloth and keeping it away from direct heat. I've seen Mississippi alligator worn daily stay intact beyond 10 years.

Why are the 'griffes' of the Constellation so important to the design?

Those claws aren't merely decorative: they protect the sapphire crystal while transforming the case into a sculptural structure. When I chose to work with this model, it was precisely that geometry that spoke to me—elegance that feels like engineering. That's why the strap must honour that architecture, never betray it.
