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.

Which leather strap is best for the Constellation 131.23.29.20.99.003?
For the 131.23.29.20.99.003, we recommend alligator leather straps for formal occasions, vegetable-tanned calf for daily durability, and shell cordovan if you desire a leather that develops a refined patina over time. The choice depends on your use case: formal, casual daily, or sporty. The aventurine dial requires straps that don't compete chromatically—we prefer dark shades or caramel tones in calf leather.
How do you change the strap on the Omega Constellation 131.23.29.20.99.003?
Remove the original bracelet/strap by gently extracting the pins with a spring bar tool (a specialized instrument with a dual flat end). Position the tool parallel to the dial, press on the internal spring of the pin to release it, and the pin will slide out of the slot. Repeat on the other side. To install the new strap, insert the pin into the new slot and let it snap into place naturally—the spring will close on its own. If you lack confidence, consult a professional watchmaker.
