The Constellation 123.55.24.60.58.002 (aka: 12355246058002), seen from the bench

The Omega Constellation 123.55.24.60.58.002 is a 24mm yellow gold quartz watch with a champagne supernova dial and diamond set bezel, featuring the iconic "griffes" on the case. This model requires a bespoke strap solution from Atelier Casati Milano to respect its integrated metal bracelet architecture and preserve the watch's precious character.

Frequently asked questions

Can a standard strap be fitted to the Omega Constellation 123.55.24.60.58.002?

No. The bracelet is integrated into the case; the lugs are not standard. A commercial strap will not fit. To change the strap, there is only one way: I handcraft it bespoke directly on your watch at <a href="/pages/casati-booking">Casati Milano</a>.

How does the bespoke strap work for this model?

Book an appointment at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15 in Milan. Bring your watch, and I take direct measurements from the case and its proprietary lugs. From there I shape the strap to your proportions and wrist, in leather chosen together.

Which leather do I recommend for the Constellation 123.55.24.60.58.002?

I prefer a natural, structured leather that ages with character. The Constellation is both sporty and elegant — it has that duality. Uncoated leather breathes better alongside yellow gold warmth. It ages well, develops patina, tells the story of time.

How long does a well-made strap last?

It depends on how you wear it. With conscious daily use, five to seven years at least. Leather ages naturally, darkens, softens. If you dirty it, clean with a damp cloth — no harsh detergents. In the end your gestures will shape it.

Why does the Constellation since 1952 remain so current?

Because the proportion is right: 24mm diameter, yellow gold, that clean dial. It does not follow trends. I have seen these watches on people who owned them twenty years ago, and they still feel true. The case architecture, with its griffes, is solid. It does not age; only the wrist wearing it changes.

The next step

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

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
