Strap for Constellation Quartz 22.5 Stainless Steel / Diamond / MOP / 160 Years

The lug width of the Omega Constellation 111.15.23.60.55.001 is 16mm. This is the vertical distance between the lateral lugs of the case. To verify it, use a digital caliper positioned between the two internal attachments, ensuring complete compatibility with 16mm straps.

For the feminine Constellation, alligator remains the traditional choice of excellence thanks to its regular grain and natural patina. Vegetable-tanned calf leather is the sustainable alternative that develops character over time. For casual occasions, a NATO strap in canvas or linen maintains elegance without formality. Shell cordovan represents the sophisticated pinnacle, although it requires custom artisanal work for the specific lug width.

The Constellation 111.15.23.60.55.001 features dedicated lateral lugs rather than standard pass-throughs. Changing the strap requires careful removal of the fixing pins (prongs) inside the lugs, using a special tool or a small controlled drill. If you are not experienced, entrust it to a professional watchmaker to avoid damaging the case.

Yes, but with caution: the 16mm lug width has a limited market. Milano Straps offers <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-16mm">16mm compatible straps</a> ready for shipment. For a personalized experience, the Casati Milano atelier creates custom straps allowing direct choice of leathers and construction details, with 18-month warranty.

Durability varies by material and usage. A high-quality alligator strap lasts 3-5 years with moderate wear. Vegetable-tanned calf leather, if well maintained, can reach 4-6 years developing a fascinating patina. Shell cordovan is the longest-lasting, reaching 6-8 years. A NATO fabric strap, being simpler, lasts 2-3 years before showing signs of wear. Regular maintenance (avoiding standing water, natural drying) significantly extends the lifespan.
