Strap for De Ville Prestige Automatic 34.7 Yellow Gold / Champagne / Bracelet

The lug width of the De Ville 4100.11.00 is exactly 20mm. To verify it, measure the distance between the case attachments from inner shoulder to inner shoulder using a digital caliper or ruler. This value is essential for choosing a compatible aftermarket strap.

Alligator represents the most versatile and aristocratic choice: its fine grain texture creates perfect tonal harmony with yellow gold and develops a natural patina over time. For those preferring dynamism, Italian vegetable-tanned calf offers superior color expressiveness. Shell cordovan, finally, adds depth and that concentrated shine that amplifies the watch's luxurious character.

To change the strap, position the watch on a soft support and use a spring bar tool to remove the attachment pins from the lugs. Insert the tool tip into the small hole beneath the pin, push gently upward to release the pin from its seat, and repeat on the other side. Once the old strap is freed, insert the new strap's pins into the lugs while keeping the pin compressed: the pin will snap into its seat when you are properly aligned.

Yes, it is possible to use a 20mm aftermarket strap on this model. However, the original De Ville features integrated attachments with very precise finishes and proportions. A custom-made strap crafted by specialized ateliers (such as Casati Milano) ensures optimal compatibility, a finish coherent with the case, and superior durability compared to generic commercial-grade straps.

The lifespan of a leather strap depends on material quality, usage, and climate conditions. A high-end alligator or shell cordovan strap maintains structural stability for 4–6 years of daily wear, with visible patina after 12–18 months. Vegetable-tanned calf evolves more rapidly (12–24 months for marked patina) but remains functional for 3–5 years. With 18-month warranty and proper care, you can expect optimal performance well beyond the first year of ownership.
