Strap for De Ville Prestige Co-Axial 39.5 Stainless Steel / Yellow Gold / Vintage Champagne

The lug width for this model is 20 mm. This dimension represents the distance between the two anchor pins of the strap to the case lugs. It is essential to measure correctly: position the watch face down and measure the distance between the two metal points, not the total width of the strap in the interface area. 20 mm maintains balanced proportions on a 39.50 mm diameter case.

For the De Ville 424.23.40.20.58.001, we recommend natural alligator or vegetable-tanned calf leather. Alligator offers pronounced grain and patina consistent with the classic aesthetic, although it requires regular maintenance. Vegetable-tanned calf provides superior longevity (6-7 years) and develops a more pronounced patina. Shell cordovan represents the premium option for durability, with smooth and metallic texture. Avoid rubber or fabric straps for daily use on this model; reserve them for sports contexts.

Remove the strap using a proper tool (spring bar tool) to extract the anchor pins from the case lugs. Position the watch face down on a soft surface to prevent scratches. Insert the tip of the spring bar tool into the small hole at the base of each lug, then gently pry to release the pin. Once removed, extract the old strap and insert the new one by aligning the holes with the lugs, then reinsert the pins. Verify proper locking before wearing the watch.

Yes, any strap with a 20 mm lug width is compatible. Verify that the strap is designed for this specific width. Artisanal quality aftermarket straps ensure thickness and finishing consistent with luxury standards. On milanostraps.it you will find a selection of customizable 20 mm straps in leather, color, and stitching. For more specific needs, the Casati Milano atelier creates custom straps with personalized material selection.

The lifespan depends on the material chosen. Natural alligator maintains functionality for approximately 4-5 years with daily use, while vegetable-tanned calf reaches 6-7 years if subjected to regular maintenance (cleaning, annual conditioning). Shell cordovan, being denser, can exceed 8-10 years. Actual lifespan varies based on environmental factors (humidity, temperatures), frequency of use, and care applied. An artisanal strap made with premium leather ages better than standard industrial straps.
