The Constellation 123.10.27.60.55.004 (aka: 12310276055004), seen from the bench

The Constellation represents one of Omega's historical collections, characterized by the distinctive design with the crown integrated into the case. This model features the Omega 1376 quartz caliber with hour and minute indication. The case presents the characteristic profile with side 'griffes', a distinctive element of the Constellation line.

Frequently asked questions

Can I fit a standard strap on the Omega Constellation 123.10.27.60.55.004?

No, the bracelet is integrated into the case. The attachment isn't a standard lug — a commercial strap simply won't connect. For a strap on this model, I build it by hand in the atelier, shaping the attachments to fit the specific anatomy of your case.

How does bespoke strap work for the Constellation?

Come to <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from your watch: I study the lug geometry, the case width, how it dialogues with the griffes. From there I craft the strap, piece by piece.

Which leather would you recommend for this Constellation?

Swift Premium. This model is elegant but carries a sporty minerality in its design — Swift breathes with the steel, ages naturally, and keeps a lightness that doesn't weigh down the wrist. If you prefer a sharper contrast, Mississippi Alligator adds density and luxury, but Swift is the instinctive choice.

How long does a well-made strap last?

It depends on use, but with care — a light dusting now and then, kept away from direct water — even five, six years of daily wear. The leather ages, develops patina, tells the story of time. It's not a failure: it's the strap breathing with you.

Why are the Constellation's griffes so important when choosing a strap?

The griffes aren't just visual — they're the architecture that defines how the strap dialogues with the case. When I build by hand in the atelier, I shape the attachments precisely around this geometry, respecting it. That's why I don't make a generic strap: every Constellation deserves a personal reading.
