The Heritage
The strap for this watch is made to measure
On the Omega Constellation the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

Can a strap be fitted to the Omega Constellation 1156.77.00?
No, not a standard strap. The integrated lugs – the four griffe – are part of the case structure and do not accommodate conventional straight spring bars. A strap can be made, built entirely bespoke on your watch by <a href="/pages/casati-booking">Casati Milano</a>. The atelier measures the case geometry and crafts the strap calibrated to your specific reference.
How does the bespoke strap work for this model?
The craftsman at <a href="/pages/casati-booking">Casati Milano</a> takes precise measurements of the griffe attachment points, width, and thickness required. The strap is built piece by piece – cut, sanded, stitched, and dyed – according to the exact coordinates of your watch. It is parallel creation with the case, not adaptation.
Which leather suits the character of the Constellation 1156.77.00?
Vegetable-tanned leathers with fine or semi-rough grain dialogue naturally with rose gold. Materials such as Hermès Étoupe, aged Pueblo, or superior-quality Veg Tan develop a patina over time consistent with the watch's evolution. Noble reptiles – crocodile or alligator – also have their place, provided they maintain a tonal restraint that does not diminish the quiet authority of the case.
How long does a well-made strap last on this watch?
A strap crafted by <a href="/pages/casati-booking">Casati Milano</a> in superior leather lasts for years, improving with wear. The patina that develops is part of its beauty: the material tells the story of time passing. Longevity depends on use and care, but a well-constructed strap is an investment as lasting as the watch itself.
Why is the Constellation 1156.77.00 considered an icon in watchmaking history?
Introduced in 1952, the Constellation was born from a celebration of certified chronometer precision. The calibre 1456 that animates it is a manual-wind movement – hours and minutes – of unspoiled Swiss reliability. The four griffe are not decorative: they are the seal of a constructive philosophy where every element is structural and representative of an era when watchmaking was wrist architecture.
