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.

How do I change the strap on the Constellation 131.23.29.20.99.001?
The strap is replaced by extracting the spring bars from the case lugs using a dedicated tool, strap lever, or multi-function tool. Position the watch on a soft pad, locate the spring bar, compress it slightly to release it, then extract it. Insert the new strap following the reverse procedure. If you lack experience, we recommend support from a professional watchmaker.
How long does a leather strap last on the Constellation?
A quality leather strap (alligator or natural calf) typically lasts 3-5 years with moderate daily use, developing an authentic patina over time that enhances its character. Longevity depends on frequency of use, water exposure, and maintenance. Casati Milano straps include an 18-month warranty and support for extending durability through personalized regenerations.
The next step
