Strap for Constellation Co-Axial 35 Stainless Steel / Grey

The lug width of the Constellation 123.10.35.20.06.001 is 22mm. This measurement corresponds to the internal distance between the two lugs of the case and is the critical parameter for selecting a compatible strap. You can verify it by positioning a digital caliper from the inner edge of one lug to the inner edge of the other.

For the Constellation 123.10.35.20.06.001 we recommend Nile alligator with vegetable tanning for uncompromised elegance, vegetable-tanned calf for a patina that ages nobly, or Tropic rubber for sporty versatility. The choice depends on use: formal occasions suggest cognac brown or black alligator; daily wear suggests calf or rubber.

Strap replacement is carried out by removing the spring bars that pass through the case laterally. You will need a Spring Bar Tool to extract the elastic pins from their slots. The Constellation 123.10.35.20.06.001, with 22mm lug width and 35mm case, accommodates straps that attach to the lugs through the metal loops at the ends.

Any 22mm strap is compatible with the Constellation 123.10.35.20.06.001, provided it is equipped with the correct loops to accommodate the case spring bars. Consult the online collection of 22mm straps to find materials, colours and finishes: alligator, vegetable-tanned calf, vulcanised rubber, shell cordovan.

A quality leather strap with vegetable tanning, worn daily, typically lasts 3-4 years before showing significant wear at pressure points (buckle, lugs). Tropic rubber lasts 5-6 years. With regular maintenance (cleaning, storage in dry environments) durability is extended. Atelier Casati Milano offers an 18-month warranty and regeneration services.
