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

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.

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.
