Strap for Constellation Co-Axial 27 Brushed Stainless Steel / MOP Supernova

The Omega Constellation with reference 123.10.27.20.55.001 is fitted with a 16mm lug width. This measurement represents the distance between the two shoulders of the spring bar holder and is essential for the compatibility of any aftermarket strap. An incorrect measurement would result in a strap that is too wide or too narrow, posing safety and aesthetic risks. On milanostraps.it you will find the complete collection of 16mm straps certified for this model.

There is no 'best' strap in absolute terms, but the choice depends on your use and personal taste. For formal occasions, dark brown or black alligator is impeccable. For those who wish to develop a patina over time, vegetable-tanned calf leather represents the ideal solution. If you seek versatility, a black NATO strap allows you to quickly alternate your style. The 27mm case of the Constellation, elegant yet robust, accommodates any of these options well.

Changing the strap on a Constellation requires extraction of the spring bar that holds the lug. You will need a dedicated tool, available from jewelers or in affordable kits online. Insert the tool into the lateral groove of the spring, apply light pressure to compress it, and remove the lug from the holder. Repeat the operation on the other side. Insert the new strap following the reverse procedure, ensuring that both spring bars are properly secured before wearing the watch.

Yes. All 16mm straps are compatible with your Constellation, provided they have the correct lug width at the ends. On milanostraps.it the collection of 16mm straps is specifically selected and tested to guarantee mechanical and aesthetic compatibility. Each strap can be customized in leather, color, texture and type of deployant clasp.

The lifespan of a leather strap depends on the intensity of use, climate and quality of tanning. A high-quality alligator strap develops a noble patina for 3-5 years of daily use before requiring replacement. Vegetable-tanned calf leather generally offers 2-4 years, as it is softer and gradually thins over time. With proper care (avoiding frequent wetting, cleaning periodically), longevity can be extended further. The Casati Milano atelier provides an 18-month warranty on every custom-made strap.
