Strap for De Ville Master Chronometer Stainless Steel / Grey / Bracelet

The lug width of the Omega De Ville 434.10.40.20.10.001 is 19mm, measured inside-to-inside of the metal bracket. This dimension is fixed and binding for the compatibility of aftermarket straps. Always verify this measurement before purchasing a replacement strap.

For this model, noble materials such as vegetable-tanned alligator, shell cordovan, or vegetable-tanned calf are recommended. The choice depends on the context of use: alligator for formal elegance with natural patina over time, shell cordovan for lasting structural sobriety, vegetable-tanned calf for chromatic versatility and daily adaptability. Avoid synthetic straps that contrast with the construction quality of the case.

Use a spring bar tool to compress the elastic pins at the ends of the original strap. Gently extract the pin from one side, remove the strap, then insert the new strap by aligning it to the lugs. Reinsert the pin and verify that it is firmly engaged. If you lack experience, entrust the task to a professional watchmaker to avoid damage to the lugs.

Yes, any strap with a 19mm lug width is physically compatible with the De Ville 434.10.40.20.10.001. However, verify that the strap has been manufactured for this specific width and that the elastic pins are of the correct length. Custom artisanal straps tailored to size guarantee perfect fit and superior longevity.

Durability depends on the material and maintenance. Vegetable-tanned alligator lasts 3–4 years with daily use; shell cordovan resists 4–5 years thanks to its fibrous structure; vegetable-tanned calf wears out in 2–3 years at medium intensity. Rubber or NATO fabric straps last 5+ years without aesthetic degradation. Regular maintenance—hydration of the leather, protection from excessive moisture—significantly extends useful life.
