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 is most suitable for the Omega Constellation 131.50.29.20.53.001 in Sedna Gold?

For the 131.50.29.20.53.001 in Sedna Gold we recommend alligator straps (cognac or dark brown), vegetable-tanned calfskin, or shell cordovan. Alligator creates chromatic harmony with Sedna Gold, calfskin develops a fascinating patina over time, while shell cordovan guarantees extraordinary durability for decades of use.

How to change the strap of the Omega Constellation 131.50.29.20.53.001?

The 131.50.29.20.53.001 features integrated lugs on the case. To change the strap, you need to use a specific tool (spring bar tool) to compress the spring pins positioned laterally to the lugs, then remove the old strap and insert the new one, verifying that it is correctly positioned on both sides.

How long does a leather strap last on the Omega Constellation 131.50.29.20.53.001?

Durability depends on the material: standard quality calfskin lasts 4-7 years with daily use, shell cordovan exceeds 15-20 years, alligator ranges around 10-15 years. Atelier Casati Milano offers an 18-month warranty on bespoke artisanal straps, with the possibility of regenerating the leather through reconditioning.
