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 you change the strap on an Omega Constellation 1886.79.40?
Changing the strap requires a specific tool (spring bar tool) or the intervention of a watchmaker. Position the flat end of the tool into the lug hole, push inward to release the spring bar, and gently extract the bar. Repeat the operation on the other side. The opposite procedure installs the new strap. In the case of an Omega Constellation with integrated bracelet, it is advisable to consult a professional to avoid damage to the case.
What is the average lifespan of a leather strap for this watch?
A quality alligator strap, if worn with moderate regularity (not daily and without prolonged exposure to moisture), lasts between 3 and 5 years before requiring replacement. Shell cordovan, due to its structural density, can reach 7-10 years. Calf leather offers an intermediate lifespan of 2-4 years. These figures depend on the type of tanning, climatic conditions, and usage habits: a perspiring wrist significantly shortens useful life.
The next step
The right strap isn’t chosen. It is built, together.
