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 strap do you recommend for the Omega Constellation 1847.76.61?

For the 1847.76.61 we recommend vegetable-tanned alligator for formal elegance, vegetable-tanned calf for everyday versatility, and shell cordovan for those seeking exceptional longevity and patina. The choice depends on occasion: black for formal wear, cognac brown for universal versatility, and burgundy or midnight blue for distinctive personality.

How long does a leather strap last on the Constellation 1847.76.61?

A quality leather strap with vegetable tanning lasts an average of 3-5 years with moderate daily use. Alligator and shell cordovan can exceed 10 years if properly maintained. Durability depends on: intensity of use, personal perspiration, sun exposure, and maintenance (regular cleaning, annual conditioning). The strap tends to wear first at the closure hole; professional repair can extend its life by 2-3 years.
