Strap for Constellation Co-Axial 27 Brushed Stainless Steel / Yellow Gold / Champagne Supernova
Integrated bracelet: measurements, the most common questions, and the way to a made-to-measure strap.
Integrated bracelet
The Omega Constellation 123.20.27.20.58.001 (aka: 12320272058001) is designed with a bracelet integrated into the case. For a compatible made-to-measure strap, the Casati Milano atelier builds it on your watch.
Frequently asked questions
Can you fit a standard strap to the Omega Constellation 123.20.27.20.58.001?
No. The Manhattan bracelet is integrated into the case — there are no standard spring bar attachments. I've seen attempts to force it, and the results are always poor. The only option is a custom-made strap built directly onto the watch in the atelier.
How does the bespoke strap work for the Constellation?
You book an appointment at <a href="/pages/casati-booking">Casati Milano</a>. Once in the atelier, I study the case geometry, the griffes, the seamless integration of the original bracelet. I measure directly on your watch, then craft the strap while respecting that millimetric architecture.
Which leather do you recommend for this Omega?
Barenia. This Constellation breathes sporting elegance — it doesn't want delicacy. Barenia has that austere character, that patina which builds over years and dialogues perfectly with yellow gold and steel. It ages honestly.
How long does a well-made strap last?
With care — dried after moisture, kept away from direct heat — between 4 and 6 years of daily wear. Then the leather changes texture, loses grip. It's not an ending: it's an ageing. We clean it, condition it, or rebuild it. Everything evolves.
Why does the 1952 Constellation still have this balance between case and bracelet?
Genta designed that geometry thinking about harmony, not just function. The sculptural griffes and the seamless Manhattan integration require precise synergy. When you change the strap, you must respect this conversation between components — otherwise the watch loses its clarity of design.
