Strap for De Ville Prestige Co-Axial 32.7 Stainless Steel / Vintage Silk Silver

The lug width of the Omega De Ville 424.13.33.20.52.002 is 16mm. This dimension represents the internal space between the case attachments where the strap fits. You can verify it by positioning a digital caliper between the two attachment eyelets on the case, measuring perpendicularly. For the 424.13.33.20.52.002, this proportion is specifically calculated for the 32.70mm diameter, creating the classic aesthetic harmony of the De Ville family.

The De Ville 424.13.33.20.52.002 expresses itself best with noble materials that enhance its classic nature. Vegetable-tanned alligator develops natural patina over time, amplifying the sobriety of the blue dial. Smooth calf (vegetable or chrome-tanned) offers minimalist formal elegance. Shell cordovan adds quiet luxury with its initial rigidity and natural luster without surface treatments. Each choice transforms the character of the watch: for maximum formality choose dark brown alligator, for contemporary modernity a cotton NATO or FKM rubber strap.

To change the 16mm strap, use a spring bar tool (a specific instrument to remove and reinstall the metal lug bar that secures the strap). Position the watch on a stable base, insert the spring bar tool under the metal lug that protrudes from the two lugs and apply slight pressure inward to make it click. Repeat on the other side. Once the old strap is removed, position the new strap by passing the lug bar through the two lugs, then reinsert the metal lug until it clicks definitively into place. If you are uncertain, the Casati Milano service performs the change with precision during custom strap selection.

No, not necessarily. Although the 16mm strap is widespread, compatibility depends on the specific lug width of each model. The 424.13.33.20.52.002 accepts exclusively 16mm straps. Before purchasing an aftermarket strap, always verify the lug width of your exact model using a caliper. Omega has used 16mm on many De Ville family models, but also on some Seamaster and Constellation models from past generations. Milanostraps provides specific 16mm straps tested for geometric compatibility.

The lifespan of a leather strap depends on the material and usage. A quality alligator or calf strap, worn daily, typically lasts 3-5 years before requiring replacement due to natural wear. Shell cordovan, more resistant, can last 5-7 years. Vegetable tanning develops protective patina that increases natural longevity. Factors that reduce lifespan: constant humidity exposure, intense sweating, storage in very dry environments. Casati Milano straps include an 18-month warranty and are made to measure to distribute load on critical points (loops, passant), significantly extending useful life compared to standard straps.
