Strap for Constellation Quartz 27 Brushed Stainless Steel / Yellow Gold / Champagne Supernova

The lug width of the Constellation 123.20.27.60.58.001 is 16mm. This measurement represents the distance between the two lugs of the case and is the essential parameter for identifying compatible straps. You can verify it by measuring with a digital caliper the internal space between the lugs at their deepest point.

Dark brown or black alligator is the most refined choice for the bicolor Constellation: the geometric, flat grain does not compete visually with the case, while the color contrast amplifies the elegance of the gold-steel bicolor design. For a more casual option, vegetable-tanned calf leather in cognac or honey tones develops a natural patina over time, creating dialogue with the 18ct yellow gold.

The strap is changed by removing the spring bars (pins) located at the ends of the lugs. Use a springbar tool by inserting the lever into the hole of the spring bar to release the mechanism. Gently extract the old strap, then insert the new one by aligning the holes with the lugs. The procedure takes approximately 2-3 minutes once you have acquired the skill.

Yes, as long as the lug width is exactly 16mm. Any strap with lugs compatible at 16mm can be mounted on your watch. Always verify the width with the manufacturer before purchase. Milano Straps offers a collection dedicated to 16mm straps with compatibility guarantee and customization options.

The lifespan depends on the material and use. A high-quality alligator or calf strap, used daily, maintains structural integrity for 3-5 years, after which stitching may require reinforcement. Vegetable-tanned leather develops a fascinating patina over time, often improving aesthetically with aging. Milano Straps guarantees 18 months on custom straps, with maintenance options and stitching replacement available.
