Strap for De Ville Small Seconds Master Chronometer Stainless Steel / Burgundy

The De Ville 434.13.41.20.11.001 uses a 19 mm lug width, a rare and specific measurement that corresponds to the proportions of the case lugs. This measurement is imperative to maintain the squared aesthetic and original proportions of the watch. It is not possible to use 18 or 20 mm straps without altering the visual balance of the case.

For a dress watch of this caliber, we recommend a black alligator or cognac brown strap, or vegetable-tanned calf leather. Antracite grey Mississippi alligator creates an elegant contrast with polished steel. If you prefer versatility, a navy cotton NATO maintains formal aesthetics while allowing quick changes. The choice depends on the context of use: galas require polished alligator, elegant daily wear prefers aged calf leather.

The strap is secured with standard 19 mm lugs. Use a spring bar tool to extract the lugs from the case, inserting the tip into the hole beneath the lug and compressing it gently. Once extracted, the strap separates from the case. To install the new strap, align the lugs with the holes and reinsert the bars by compressing them until they lock. If you do not have specific tools, the operation is recommended at a watchmaker or at Casati Milano.

Yes, all artisanal straps with 19 mm lug width are compatible with this model. On milanostraps.it you will find a wide collection of 19 mm straps in alligator, calf, shell cordovan and rubber, customizable in size, initials and stitching color. Casati Milano also makes custom straps with personal leather selection and 18-month warranty.

Durability depends on the material and usage. A superior quality alligator or vegetable-tanned calf strap lasts 3-5 years with ordinary maintenance (monthly cleaning, limited sun exposure). Mississippi alligator is more resistant than American alligator and develops a protective patina over time. FKM rubber resists 4-6 years without aesthetic deterioration. To extend the life of the strap, avoid saltwater, hydrate it periodically with creams specific for leather, and store it away from direct sources of heat.
