Strap for Constellation Co-Axial 27 Brushed Yellow Gold / Diamond / MOP Stars

No, the Manhattan bracelet is integrated directly into the case. A standard strap has nothing to attach to. I've seen many owners search for workarounds: the only serious solution is to have a custom strap made, shaped to the specific lug geometry of this watch. That's what we do in the atelier.

We work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15 in Milan. I take measurements directly from your case, millimetre by millimetre. I hand-craft the attachment so the strap integrates perfectly with the yellow gold architecture and respects the original case proportions.

I prefer polished Mississippi alligator. This watch carries both sporty and elegant character, and alligator speaks well to yellow gold without competing with the four-claw bezel. The smooth grain echoes the watch's technical precision, and it ages into a patina that deepens over time.

A strap built from serious leather lasts 8–12 years with regular wear, depending on how you treat it. Good leather ages rather than wearing out: it develops a patina that tells the story of time passed. I recommend removing the watch at night and not soaking it regularly. Care is simply respect.

It's a design choice: Omega conceived case and bracelet as a single architectural unit, not as separate components. This means structural rigidity and proportions refined to the detail. The cost of that precision is you can't swap straps in a minute—but when you do it bespoke, the result is incomparably more elegant than a watch with standard lugs.
