Strap for De Ville Master Chronometer Stainless Steel / Grey

The lug width of the Omega De Ville 434.13.40.20.10.001 is 19mm. This measurement is the space between the lateral pins of the case and determines direct compatibility with aftermarket straps. Always verify this dimension before purchasing a replacement strap, as an incorrect measurement would result in poor fit and structural risks to the fastening mechanism.

Vegetable-tanned alligator represents the most elegant pairing and is coherent with the De Ville identity, thanks to its regular grain and natural patina that develops over time. However, English or French calf and shell cordovan offer versatile alternatives. For more intense use or humid environments, satin FKM rubber straps maintain the balance between functionality and aesthetics. Avoid NATO straps or military fabrics: the 40mm diameter and classic case line require a strap that communicates constructive intent, not casualness.

To change the strap without damaging the case, it is necessary to use a specialized tool to remove the spring bars. Position the Omega on a soft surface, protecting the case with a cloth. Using a spring bar tool, gently push it inward to free the pin from the terminal, working on both sides. Once the pins are extracted, the strap will be released. Reverse the procedure to install the new strap, ensuring that the pins insert completely into the terminal holes. If you are not experienced with this operation, consult a specialized atelier.

The lifespan of a leather strap depends on the material and intensity of use. A quality vegetable-tanned alligator strap, worn daily, can last 4-8 years before showing signs of structural wear (seam failure or fiber damage). Softer calf tends toward a slightly shorter lifespan (3-6 years), while shell cordovan, being denser, can last 10+ years. Exposure to UV rays, sweat, and humidity accelerates degradation. Regular maintenance (cleaning with a damp soft cloth, avoiding wetting the strap) and rotation among multiple straps extends overall longevity. Casati Milano straps include an 18-month warranty against manufacturing defects.
