Strap for De Ville Co-Axial Annual Calendar Platinum / White

The lug width measures exactly 20mm. This dimension is essential to ensure proper strap compatibility. You can verify it by measuring the distance between the attachment pins protruding from the case. Do not confuse it with 22mm (typical of tool watches) or 16mm (more compact dress watches).

Alligator with natural grain is the most appropriate material from both aesthetic and construction perspectives. Shell cordovan offers formal luster and an evolving patina over time. Vegetable-tanned calf provides elegance with visible aging. Silk satin NATO also works for a more contemporary approach.

Not all De Ville models have integrated lugs—verify your specific model. If present, integrated lugs are soldered and non-removable. In this case, you work with straps that attach to the side slots of the case. Casati Milano offers precise measurements and creates custom 20mm straps for this specific configuration.

All straps with 20mm attachment are technically compatible. Milano Straps offers online a dedicated collection of <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-20mm">20mm straps</a> with customization options. For bespoke results without compromise, the Casati Milano atelier creates custom straps with direct leather selection and an 18-month guarantee.

A high-quality artisanal alligator strap lasts 3-5 years with daily wear. Shell cordovan, if kept dry, reaches 4-7 years. Vegetable-tanned calf ages visibly but remains functional for 2-3 years of intense use. Durability depends on climate, frequency of wear, and maintenance (avoid moisture, clean regularly with a soft cloth).
