Strap for Constellation Co-Axial 35 Stainless Steel / Yellow Gold / Champagne

The Omega Constellation 123.20.35.20.08.001 features a lug width of 18 millimeters. This measurement represents the space between the two lugs on the case where the strap attaches. Verifying the measurement with a digital caliper, positioning it perpendicularly between the lugs, is essential to ensure perfect compatibility and safe use.

For the 123.20.35.20.08.001 we recommend alligator for formal contexts and shell cordovan for daily wear with patina development. If you prefer sustainability, vegetable-tanned leather (cognac or deep brown) creates an extraordinary aesthetic dialogue with the yellow gold of the two-tone case. FKM rubber represents the ideal choice for versatility and practicality of use.

The strap is changed by acting on the sprung bars located at the ends of the lugs. Using a dedicated tool or a small flat-head screwdriver, you disengage the internal spring of the bar, allowing the strap end to slide out. The operation requires care to avoid damage to the case. If inexperienced, consult a qualified watchmaker or contact our Casati Milano atelier.

Yes, any handcrafted strap in 18mm lug width is compatible with this model. You will find a wide selection of ready-to-ship straps online, or you can order a custom piece from the Casati Milano atelier, personalizing leather, color, initials, and stitching thread according to your aesthetic preferences.

A handcrafted quality leather strap, used daily under normal conditions, maintains structural integrity between 3 and 5 years. Durability depends on the tanning method (vegetable-tanned resists humidity better than alligator), climate, frequency of use, and maintenance. Leather naturally evolves: this aging is desirable. Casati Milano straps include an 18-month warranty against manufacturing defects.
