Integrated bracelet
The Omega Constellation 111.20.23.60.55.001 (aka: 11120236055001) 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 on the Omega Constellation 111.20.23.60.55.001?
No, the bracelet is integrated directly into the case – there are no standard lugs to attach a strap. I've seen many owners ask about changing it, but a standard strap won't fit. In the atelier I build a custom attachment directly on the case, respecting the original geometry.
How does the bespoke strap work for this model?
We work exclusively at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from your case, point by point. It's the only way to ensure the strap fits perfectly without compromise.
Which leather would you recommend for the Constellation?
I prefer Mississippi Alligator in Blanc Naturel. This watch has an elegant but direct character – yellow gold and steel together, mother of pearl dial – and alligator ages quietly, without theatrics. The natural texture of the leather speaks well with light on the wrist.
How long does a well-made strap last?
With regular care, 5 to 7 years at least, depending on use. Leather ages, darkens, develops a patina – that's part of its character. I recommend having it checked every two years and keeping it dry. A good strap is an investment, not an expense.
Why was the Constellation created as a tribute to observatory chronometers?
In 1952, Omega wanted to celebrate astronomical precision, not just a style. The griffes – the claws around the sapphire crystal – aren't ornament: they hold the crystal firmly and became the visual code of the collection. It's a detail that speaks to how Omega thinks: form and function inseparable.
