Frequently asked questions

Can I fit a standard strap on the Omega Constellation 1156.77.00?

No. The bracelet is integrated into the case. The lug attachment is proprietary — designed for the original "griffes". A standard strap won't engage. The solution is to have the strap built bespoke, directly on the watch.

How does the bespoke strap process work for this model?

We work at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from the case, study how the strap must integrate with the griffes. Every piece is hand-shaped to respect the original architecture.

Which leather do I recommend for a rose gold Constellation?

Mississippi alligator, burnished. The Constellation breathes sportive elegance, and alligator gives it substance and warmth without overloading it. The leather texture speaks well with rose gold — they age together, and the result improves over years.

How long does a well-made strap last?

It depends on use and care. With a hand-built strap, you see the leather change colour over time, the hide breathe. It lasts 8 to 12 years, sometimes longer. If you treat it well — no standing water, no direct sun for days — the leather ages with grace and you won't want to leave it.

Why are the "griffes" so important on this model?

They are the signature of the Constellation since 1952. Four lugs embracing the sapphire crystal — not decoration, it's architecture. When we build the strap, we respect them in every millimetre. It's the detail that sets this watch apart and must remain intact.

The next step

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