The Heritage
The strap for this watch is made to measure
On the Omega Constellation the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

Can you fit a strap on this Omega Constellation?
No, the Manhattan bracelet is integrated into the case — there are no standard lugs to attach a conventional strap. I've seen many try, then realise this architecture is intentional. To transform it, you need <a href="/pages/casati-booking">Atelier Casati Milano</a>, where we build a bespoke strap directly on the watch.
How does bespoke strap work on the Constellation 123.25.27.20.58.001?
We work by appointment only, at Via XX Settembre 15. I measure the case and lugs directly from your watch, study the curve and the transition between yellow gold and steel. Everything is personal: the strap is built for that specific case, nothing off-the-shelf.
Which leather do you prefer for the Constellation?
Swift. This watch has a sporty-elegant character that resists formality — Swift moves with the wrist in natural softness, respects the precious metals without shouting. Alligator Mississippi works if you want something more assertive, but Swift reads the spirit of the model.
How long does a well-made strap last?
It depends on your habits. With daily care, 3–4 years of clean life; then it shows traces. Good leather ages well — it darkens, it develops patina, it tells a story. If you keep it away from water and humidity, it lasts longer. It's not eternal, but it's alive.
Why was the Constellation born in 1952 and what keeps it relevant today?
Omega designed it as an answer to the mechanical watch crisis: it had to prove that design and precision could exist together without compromise. The 'griffes', the 27mm case, the Manhattan — all of it is architecture, not decoration. It's still relevant because the drawing doesn't age when it's built to last.
