Strap for De Ville Prestige Co-Axial 39.5 Stainless Steel / Black / Bracelet

The lug width is 20 mm. This measurement is the distance between the two pins of the spring bar that anchor the strap to the case. Do not confuse it with the total strap width: 20 mm is the strict standard for mechanical compatibility with this model.

It depends on usage and aesthetic preference. An American Porosus alligator with honey patina offers vintage-contemporary elegance ideal for everyday wear. Italian vegetable-tanned calf proposes a daily alternative with natural patina. A burgundy shell cordovan transforms the model into formal wear without excess. An anthracite FKM rubber reinterprets the watch as an intelligent tool watch. The choice depends on your predominant wear context.

Get a spring bar tool (a thin lever tool with slots at both ends). Position the lever in the two side holes of the spring bar, pressing inward: the central pin retracts, releasing the strap. Repeat on the other side. To install the new strap, align the pin with the spring bar hole and press until you hear a click lock. Verify that the strap is securely attached by gently pulling.

Yes, provided the strap is specifically dimensioned for a 20 mm lug width. Handcrafted online straps or custom shop products guarantee compatibility when the lug width is certified. Avoid unverified generic straps: an incorrect measurement, even by 0.5 mm, can cause excessive play or irregular pressure on the spring bars.

Durability depends on the intensity of wear, climatic conditions, and leather quality. A handcrafted alligator or shell cordovan of high quality, with regular maintenance (monthly cleaning with a damp cloth, semi-annual conditioning with specific creams), lasts 5-8 years before showing structural deterioration. Vegetable-tanned calf ages more rapidly visually—developing a fascinating patina in 2-3 years—but remains functional for 6-10 years. The Casati Milano standard warranty is 18 months, covering manufacturing defects.
