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

What is the best strap material for the Constellation 1590.70.00?

Alligator leather with vegetable tanning represents the traditional choice: the small-scale texture returns a refinement that the case steels accentuate. Notable alternatives are vegetable-tanned calf leather (quick patina development) and shell cordovan in burgundy or black for a more contemporary approach.

How do you change the strap on an Omega Constellation 1590.70.00?

The 1590.70.00 features an integrated bracelet. Removing the original bracelet requires watchmaking expertise: the lugs are not user-removable. Contact a certified watchmaker or specialized atelier for replacement, which often requires specific tools to preserve the case.

How long does a leather strap last for the Constellation 1590.70.00?

A quality leather strap (alligator, calf, shell cordovan) with vegetable tanning lasts an average of 3-5 years with daily wear. Durability depends on frequency of use, exposure to moisture, and care: avoid prolonged water contact and apply protective balms annually. Casati Milano straps include an 18-month warranty and are regenerable.
