Strap for Constellation Quartz 22.5 Yellow Gold / Diamond / Champagne Supernova / 160 Years

The Omega Constellation 111.55.23.60.58.001 has a lug width of 18mm. This compact proportion is specific to the model and ensures visual balance on a 22.50mm case diameter. You can verify it by measuring the space between the two lugs with a ruler. Milano Straps offers 18mm straps in various leathers: alligator, vegetable-tanned calf, rubber, and technical fabrics.

Natural alligator (caiman or Nile) represents the most coherent pairing with 18-karat yellow gold: regular scales and fine grain enhance the luminosity of the case. Vegetable-tanned calf develops patina over time, creating a honeyed tone that harmonizes the watch with the wrist. For modern aesthetics, a translucent smoke-grey rubber strap maintains proportion without adding weight. The choice depends on context of use and personal color palette.

The Constellation features integrated lugs: the horns are part of the case and non-removable. Strap change occurs via spring bars or pins that pass through the lugs. Using a spring bar tool, you remove the pin from inside the lug, freeing the old strap. Installation of the new strap requires the same tool: insert the pin into the new strap ends and secure it to the lugs. For precision and safety, entrust the task to a professional watchmaker.

Any 18mm strap with standard spring bar attachment is compatible with the 111.55.23.60.58.001, provided it has suitable spring bars or pins. Milano Straps offers customizable 18mm straps online: alligator, satin calf, shell cordovan, rubber, and technical fabrics, all with an 18-month warranty. The Casati Milano atelier creates bespoke straps with personal leather selection and direct updates via WhatsApp, for perfect adjustment to the wrist and case movement.

The lifespan of a leather strap depends on the material, tanning method, and daily use. A quality vegetable-tanned calf develops pleasant patina in 2-3 years and easily resists 4-5 years of moderate use. Alligator, more durable, exceeds 5 years. Rubber and technical fabrics maintain functionality for 3-4 years of intensive use. Factors accelerating wear: prolonged sun exposure, constant humidity, perspiration. Milano Straps offers an 18-month warranty on all straps and proposes progressive replacements for those who want to vary their look while keeping the watch.
