Strap for De Ville Prestige Co-Axial 39.5 Stainless Steel / Vintage Silver

The Omega De Ville 424.13.40.20.02.003 requires a lug width of exactly 20 mm. This is the distance between the spring bars that attach the strap to the case. To verify, measure with a digital caliper perpendicular to the spring bars, from outer edge to outer edge. Straps narrower (18 mm) or wider (22 mm) will not fit correctly.

The choice depends on use and personal style. Medium-toned brown alligator emphasizes the sobriety of the formal design; vegetable-tanned calf leather ages with elegance and develops patina over time; premium canvas NATO offers versatility and quick changes; FKM rubber remains ideal for humid climates or summer. All these materials maintain the proportions of the 39.50 mm case.

The De Ville uses standard spring bars. Use a spring bar tool to compress the elastic pins and remove them from the case lugs. Insert the new strap by aligning the spring bars to the lugs, then release pressure until the safety click. If you lack experience, entrust the task to a watchmaker to avoid scratches on the case.

Yes, provided the strap has a 20 mm lug width. Compatibility is determined by spring bar geometry, not by brand. However, a custom handcrafted strap (such as those by Casati Milano) guarantees optimal proportions and finishes for this specific model, enhancing its elegance.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3–5 years with moderate daily wear, up to 8–10 years with occasional or sporadic use. Lifespan depends on sun exposure, humidity, frequency of wear, and care. Vegetable-tanned leather ages well and can develop fascinating patina even beyond 5 years. Artisanal warranty (such as Casati Milano's 18-month warranty) covers manufacturing defects and abnormal wear.
