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

The Omega De Ville 424.20.40.20.02.001 has a lug width of 20 mm, measured between the inner walls of the lugs. This parameter is critical for compatibility with aftermarket straps: all straps designed for this width will fit perfectly without requiring any modifications.

The choice depends on usage and aesthetic preference. For formal occasions, we recommend dark brown or black alligator with a gold deployant clasp, which enhances the two-tone case. For daily wear, vegetable-tanned calf leather offers natural patina and versatility. If exposed to high humidity, an FKM rubber strap guarantees superior environmental resistance while maintaining elegance.

Remove the spring bars that connect the lugs to the strap. Use a spring bar tool to push the bar inward, releasing the old strap. Insert the new strap by aligning the holes and snap the spring bar into the slots until you hear the click securing it. If you are not experienced, the Casati Milano atelier offers strap replacement service at the Milan location by appointment.

Yes, all straps catalogued in the 20 mm size are compatible with the De Ville 424.20.40.20.02.001. Compatibility is guaranteed by the standard 20 mm lug width. Milanostraps also offers customization (size, initials, thread color) and the option for bespoke commissions at the Casati Milano atelier.

Durability depends on the material and usage. A quality alligator strap with vegetable tanning lasts 5-8 years with regular wear; vegetable-tanned calf develops patina within 6-12 months and maintains functionality for 7-10 years. In high-humidity environments or with frequent perspiration, durability decreases by 20-30%. Milanostraps guarantees its straps for 18 months and offers regeneration and maintenance services at Casati Milano.
