The Heritage
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.

What strap do you recommend for the Constellation 1154.75.00?
For a yellow gold timepiece of this caliber, we recommend vegetable-tanned alligator (black, dark brown, or burgundy) as the first choice. Vegetable-tanned calf represents a softer and more refined alternative. For those seeking durability and the beauty of evolved patina, shell cordovan is the noblest solution. Avoid synthetic materials that would visually detract from your gold investment.
How do I change the strap on my Omega Constellation 1154.75.00?
The replacement requires the use of a spring bar tool. Position the tool on the horizontal pin of the strap from the dial side, gently press to release the pin, remove the strap, then repeat on the other side. When installing the new strap, align the holes and push the pins until they click into place. If you prefer to avoid the risk of scratching the crystal, Casati Milano atelier can perform the operation for you.
How long does a natural leather strap last on an Omega Constellation 1154.75.00?
Durability depends on the tanning method, use, and maintenance. A high-quality vegetable-tanned strap (alligator, calf, shell cordovan) maintains aesthetic and functional integrity for 3–5 years with daily wear, and beyond 10 years with occasional use. Natural patina development is desirable; deterioration begins when the leather starts to thin or separate from the stitching. Casati Milano straps carry an 18-month warranty against manufacturing defects.
