Strap for De Ville Prestige Co-Axial 36.8 Stainless Steel / Red Gold / Silver / Diamond / Bracelet

The lug width for this model is 19 millimetres. This dimension is the essential parameter for identifying compatible straps. It is measured by positioning a digital caliper on the inner shoulder of the lug, from edge to edge, excluding the radius of curvature. Any strap intended for this watch must have a nominal width of 19 millimetres.

Alligator represents the most coherent choice: the regular grain texture and natural patina of the leather pair perfectly with the lacquered blue dial and applied indices. Fine calf is an elegant alternative if you prefer a more homogeneous texture. For intensive use, shell cordovan offers superior resistance and a patina that deepens over time. All these materials are available in customizable 19mm straps at the Casati Milano atelier.

The strap is changed simply by extracting the spring bars that connect the lug to the case. On this two-tone gold-steel model, the spring bars are typically stainless steel. Using a dedicated tool (available free of charge at Omega retailers or easily found online), gently lift the strap and extract the spring bar from one end. Next, insert the new strap by aligning the holes with the lugs and reinsert the spring bar. The operation requires no special skills and can be performed at home in less than a minute.

Yes, completely. Any strap with a 19 millimetre lug width is compatible with this model. Many artisanal manufacturers, including Casati Milano, offer 19mm straps crafted in noble leathers (alligator, calf, shell cordovan, vegetable-tanned leather) with finishes and customizations unavailable in the mass-market. Compatibility is guaranteed by the standardization of lug width; the construction quality of the strap depends on the manufacturer's choice.

The lifespan of a natural leather strap on a watch worn daily like the De Ville 424.25.37.20.52.001 depends on multiple factors: the type of tanning (vegetable vs. synthetic), the material chosen (alligator tends to have greater longevity compared to thin calf), intensity of use, exposure to moisture and sunlight, and maintenance. Under normal conditions of professional wear, a strap in alligator or shell cordovan guarantees a lifespan of 3-5 years before visible wear begins to appear. With regular maintenance (drying after moisture contact, occasional conditioning with natural waxes), this lifespan extends. The Casati Milano atelier offers an 18-month warranty on all straps produced, covering manufacturing defects, but preventive replacement every 3-4 years is recommended to maintain aesthetic appearance.
