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

Which strap material is most suitable for the Constellation 1173.76.00 in white gold?

Alligator remains the most natural choice for the 1173.76.00 in white gold, thanks to its caracollo texture that optically complements the surface texture of white gold and the case lugs. Shell cordovan represents the premium alternative for those desiring a patina that becomes richer over time. Vegetable-tanned calfskin offers a modern balance between lightness and the promise of noble aging.

How do you change the strap on a watch with integrated lugs?

Watches with integrated lugs (such as the 1173.76.00) require the use of a specific tool to remove the pin that connects the strap to the lugs. The operation cannot be performed manually: it is necessary to resort to a professional watchmaker or specialized services such as Casati Milano, which has the appropriate tools and expertise to avoid damaging the case during the intervention.

How long does a leather strap last on a watch like the Constellation 1173.76.00?

The lifespan of a leather strap depends on the quality of the raw material, the tanning process, and the intensity of use. A strap in excellent shell cordovan or alligator can maintain structural integrity for 5-8 years of daily use, developing an increasingly fascinating patina. Calfskin, being more delicate, tends to show the first signs of wear around 3-5 years. The 18-month warranty offered by Casati Milano covers manufacturing defects and ensures replacements in case of issues due to craftsmanship.
