Frequently asked questions

Can you fit a standard strap on the Omega Constellation 1561.61.00?

No. The bracelet is integrated into the case — there are no standard lugs for a strap. I've seen many owners try DIY solutions: nothing really works. The only proper way is to have a custom strap built directly in the atelier.

How does the custom strap work for this Constellation?

I work only at <a href="/pages/casati-booking">Casati Milano</a>, by appointment. I take measurements directly from the case — I observe how the watch sits on the wrist, how the griffes move, where the strap must anchor. Then I build everything by hand, once, designed for that specific case.

Which leather do you recommend for the Constellation?

Mississippi Alligator if you want it for evening wear — the leather has a softness that respects the quiet elegance of this watch. For daily use I prefer Swift, which ages better and keeps the sporty-elegant character of the model. Nothing flashy: the Constellation doesn't shout.

How long does a well-made strap last?

With care, 4 to 6 years of regular wear. It depends on how often you wear it, humidity, how many times you get it wet. Good leather doesn't die — it changes colour, it gets marked, it tells time. If you treat it well, it ages in a way you'd never achieve with a new one.

Why does the Constellation 1561.61.00 have that distinctive design with the griffes?

The griffes aren't decoration — they're structural attachments that come from the 1950s, when Omega had to prove chronometric strength through form as well. That integrated bracelet is architecture: if you remove the strap, you're left with a case that speaks for itself. That's why you can't improvise — the strap must dialogue with that geometry.

The next step

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