Strap for De Ville Prestige Co-Axial 39.5 Stainless Steel / Vintage Silver Silk / Bracelet

The lug width of the Omega De Ville 424.10.40.20.02.004 is 20mm. This measurement is taken between the case attachment terminals, excluding the side lugs. It is essential to verify this measurement before ordering a compatible strap to avoid mounting errors.

For this model we recommend genuine alligator for sartorial elegance with noble patina, vegetable-tanned calf for sobriety and everyday durability, or shell cordovan for collectors who appreciate density and natural luminosity. The choice depends on the use context: formal, business, or weekend.

The strap is changed using a spring bar tool (a special tool to remove the fixing pins). Position the watch on a stable surface, insert the tool into the small hole under the lug, gently lift to compress the internal spring of the pin, and slide out the old strap. Proceed with caution to avoid scratching the case. If you are unsure, consult a professional.

Yes, provided the strap has a certified 20mm lug width. We recommend artisanal materials from specialized suppliers that respect the proportions of the 39.50mm case. A strap of superior quality to the stock model can transform the wearing experience without compromising the technical authenticity of the watch.

A genuine leather strap, with proper maintenance (drying after humidity exposure, biannual conditioning with specific creams), lasts an average of 3-5 years of daily use. Shell cordovan can exceed 7 years. Vegetable-tanned alligator maintains structural integrity for 4-6 years before requiring professional reconditioning.
