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

How do you change the strap on an Omega Constellation?

Changing the strap on a Constellation 131.15.25.60.55.001 is done by unscrewing (not extracting) the lug pins with an appropriate tool (spring bar tool). Remove the old strap, insert the new pins into the new strap respecting the orientation, and screw back in place. If you are unsure, consult a watchmaker: Casati Milano offers complete strap change assistance.

How long does a leather strap last on an Omega Constellation?

An artisanal alligator or vegetable-tanned calf strap on a Constellation 131.15.25.60.55.001 typically lasts 3 to 5 years of regular use. Durability depends on seasonal use, body perspiration, and sun exposure levels. With vegetable tanning, the strap develops a pleasant patina and can be rejuvenated with maintenance every 2 years. Casati Milano guarantees 18 months on custom straps made in our atelier.
