Strap for Constellation Quartz 24 Polished Stainless Steel / Yellow Gold / Diamond / MOP Supernova

The Omega Constellation 123.25.24.60.55.008 has a lug width of 20mm. This measurement is essential for selecting a compatible strap: the strap must fit perfectly between the spring bars of the case without leaving gaps or forcing. We recommend measuring directly the distance between the two spring bars with a caliper or ruler to confirm compatibility before purchase.

Given the elegant and feminine character of this two-tone model, we recommend straps in noble leather: alligator for maximum aesthetic refinement, soft calf leather for everyday comfort, or shell cordovan for a noble patina with aging. For sports use, heavy cotton NATO fabric or FKM rubber ensures protection and breathability on the wrist. The choice depends on your intended use and personal style.

Strap change requires the use of a spring bar tool to extract the spring bars. Locate the horizontal pins that connect the strap to the case, insert the tool's tip into the small release hole, gently lift the pin until it snaps out, and repeat on the other side. After removing the old strap, insert the new strap's pins in the same way, ensuring they are fully seated. If you are not experienced, contact the Casati Milano atelier for professional service.

A quality leather strap has an average lifespan of 3-5 years of regular use, depending on the material, exposure to sun, sweat and humidity. Maintain it with natural waxes every 6-8 months, avoid prolonged contact with salt water and clean it with a soft damp cloth. The 18-month warranty on all Casati Milano straps protects you from manufacturing defects. When the leather begins to mark or weaken, it is time to renew the strap to keep your Omega in perfect condition.
