Frequently asked questions

Can I fit a standard strap on the Omega Constellation 123.20.24.60.55.002?

No, the bracelet is integrated into the case — the attachment is not standard. An off-the-shelf strap simply won't fit. In the atelier I build the strap directly onto your case, hand-modelling the attachments to align perfectly with your original lugs.

How does the bespoke strap project work for this model?

I work exclusively at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from your case — no distance guesswork. This is the only way to respect the Constellation's integrated geometry and guarantee a seamless result.

Which leather do you recommend for the Constellation?

I favour premium Swift in tones that dialogue with the mother-of-pearl — milk white, champagne, pearl grey. For those wanting sharper contrast, Mississippi Alligator with small scales brings discreet luxury to the 24mm case, without adding weight.

How long does a well-made strap last?

Built properly and worn with care, 8-10 years without issue. Leather ages naturally, developing patina — not a fault, but the memory of time. Light maintenance now and then (neutral cream, proper drying) keeps the strap supple and alive.

Why was the Constellation designed with an integrated bracelet?

Omega conceived this architecture in 1952 to emphasise precision and solidity — the lugs embrace the crystal and the case forms one body. It's an aesthetic and structural choice that demands respect. For this reason, a bespoke strap is the only path: it doesn't adapt, it's built.

The next step

The right strap isn't chosen. It is built, together.
