Frequently asked questions
Can I fit a standard strap on the Omega Constellation 123.55.27.60.55.003?
No, the bracelet is integrated into the case. There is no standard lug where you can attach a strap. I've seen many owners try DIY solutions: I don't recommend them. In the atelier, I build a custom strap directly on the geometry of your case.
How does the custom strap process work for this model?
We work only at <a href="/pages/casati-booking">Casati Milano</a>, by appointment. I take measurements directly from your case, study the architecture of the lugs, and shape the strap by hand so it integrates seamlessly. It's not standard work.
Which leather do you recommend for the yellow gold Constellation?
I prefer Mississippi Alligator or Swift in warm tones – honey, cognac, chocolate. This model has a sporty elegance that doesn't want to be overwhelmed by cold colours. Dark leather speaks to yellow gold without competing.
How long does a well-made strap last?
A good strap lasts 4–6 years with daily wear, sometimes longer if you treat it with respect. Leather ages, develops patina, shifts colour slightly. It's not a flaw: it's the story of your watch writing itself.
Why does the Constellation have those protrusions on the case?
The lugs – the claws on the case – are the signature of the Constellation since 1952. They demand absolute respect for their geometry. That's why the strap can't be approximate: every millimetre counts to preserve the architecture Omega designed.
