The Constellation 123.20.24.60.58.001 (aka: 12320246058001), seen from the bench

The Constellation Quartz 24 Brushed Stainless Steel / Yellow Gold / Champagne Supernova is a 24mm bicolor timepiece embodying Omega's 1952 vision of combining chronometric precision with aesthetic refinement. The model features the iconic integrated Manhattan bracelet fusing case and strap into a single sculptural architecture, characterized by the signature four "griffes" embracing the bezel.

Frequently asked questions

Can I fit a standard strap on the Omega Constellation 123.20.24.60.58.001?

No, the bracelet is integrated into the case. The lug attachment is not standard — the geometry of the lugs and the Manhattan bracelet require a bespoke solution. I build it custom in the atelier, directly on your watch.

How does the custom strap work for this Constellation?

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15 in Milan. I take measurements directly from the case, study how the integrated bracelet interacts with the lugs, and craft a millimetre-precise attachment that respects the two-tone steel and gold architecture.

Which leather do you recommend for this model?

I prefer Swift or Mississippi Alligator. This Constellation has a dual character — feminine elegance but solid — and the leather must dialogue with the steel and yellow gold without competing. Neutral or earth tones let the two metals speak.

How long does a well-made strap last?

With care, 5 to 8 years of regular wear. Leather ages: it shifts in tone, develops patina. That's not a flaw — it's the mark of a relationship with your watch. Protect it from moisture and direct sweat, and it will have a long life.

Why does this Constellation require special attention in the atelier?

The lugs — the four 'griffes' that frame the bezel — are the soul of the design. The Manhattan bracelet fuses case and strap into one form. I cannot improvise: I study the geometry, respect both metals, and create an attachment that amplifies the original aesthetic, not betrays it.

The next step

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