Strap for Constellation Co-Axial 35 White Gold / Diamond / MOP Supernova / Rubber

The lug width of the 123.58.35.20.99.001 is exactly 20mm. This measurement, also known as lug width, defines the internal distance between the case lugs where the strap attaches. Measured correctly with a digital caliper, it ensures that the strap rests perfectly on the case shoulders without lateral protrusions or play. Any strap intended for this model must be strictly 20mm.

The best strap depends on the dial tone and the occasion of use. For maximum elegance, blonde alligator on a champagne dial or dark brown on a silver dial offer optimal proportions. Shell cordovan is ideal for those who appreciate the natural patina that develops over time. Full-grain calf leather with vegetable tanning represents an excellent compromise between versatility and aesthetics. The choice of a white gold deployant buckle completes the harmony with the case.

The strap of the 123.58.35.20.99.001 is replaced using a spring bar tool. Position the watch on a soft surface, locate the small groove under the lug, insert the tool to compress the internal spring and remove the lug. Repeat the procedure on the opposite lug. To avoid damage to the sapphire crystal, we recommend entrusting the operation to an authorized Omega service center or a professional watchmaker.

All straps with a 20mm lug width are compatible with the 123.58.35.20.99.001. On milanostraps.it you will find a complete collection of aftermarket straps in alligator, shell cordovan, calf, rubber and fabric, all available in 20mm size. Each strap can be customized in length, initials and thread stitching color. For a complete bespoke experience, the Casati Milano atelier creates custom straps with personal selection of hides.

The durability depends on the material chosen and the frequency of use. A watchmaking-grade alligator strap lasts an average of 3-5 years with moderate daily use; shell cordovan, thanks to the density of the material and natural patina, can exceed 7 years; full-grain calf leather with vegetable tanning has a lifespan of 2-4 years. A Casati Milano strap, with an 18-month warranty, is made with naturally tanned hides selected for durability and lasting aesthetic beauty. Seasonal rotation between straps significantly extends the life of each one.
