Made to Measure

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.

FAQ

What is the best strap for the Omega Constellation 1297.75.00?

It depends on use and wrist size. For formal elegance: dark brown alligator, vegetable-tanned calf, or burgundy shell cordovan maintain the balance of the two-tone case design. For casual versatility: pearl grey NATO or light grey rubber. The key is choosing a leather or material that doesn't compete with the mother-of-pearl dial for luminosity.

How do I change the strap on my Omega Constellation 1297.75.00?

You have two options: DIY strap change with a specialized tool (lug bar or spring bar tool), which requires care not to scratch the two-tone case, or entrust it to a professional. The Casati Milano atelier offers free strap replacement if purchased through them, with complete case inspection during the operation.

How long does a leather strap last on my Constellation?

A premium alligator strap lasts 5-7 years with daily wear; calf leather 3-5 years; shell cordovan 6-8 years thanks to the greater density of the leather. Durability depends on humidity, sun exposure, and frequency of use. The Casati Milano atelier guarantees 18 months on all handcrafted straps, with the possibility of maintenance and controlled aging.
