Strap for De Ville Co-Axial 41 Chronoscope Stainless Steel / White / Olympic Timeless

The lug width of the De Ville 4846.20.32 is 18mm. This dimension is measured perpendicularly to the case lugs at the point where the original strap attaches, using a digital caliper for precision. The 18mm lug width represents the optimal proportion between the case diameter (41mm) and the visual thickness of the strap, ensuring aesthetic balance.

There is no universal solution, but choices coherent with the aesthetic narrative. For maximum formality: matte black alligator. For narrative warmth: cognac calf with aged patina or vegetable tanning. For supreme durability: shell cordovan. For minimalist contemporaneity: satin-finished gray or black rubber. The choice depends on the intended use and the wearing context of the timepiece.

The strap is secured by the lateral lugs (pins) of the case. Use a dedicated tool (spring bar tool or strap removal lever) to depress the pins from the back of the case. Position the new 18mm strap by aligning the lateral holes, then reinsert the pins carefully until the click engagement locks. We recommend entrusting this operation to a qualified professional to avoid damage to the case.

Yes, the 18mm lug width allows for the installation of a wide range of commercially available aftermarket straps. However, construction quality varies considerably. To maximize aesthetic harmony and durability, we recommend straps crafted artisanally with premium leathers: alligator, shell cordovan, calf with vegetable tanning. Milano Straps offers 18mm straps ready for shipment and customizable, as well as the possibility of bespoke commissions at the Casati Milano atelier.

Durability depends on the material, tanning method, and usage. A standard calf (full grain) resists an average of 3-4 years with daily wear. A shell cordovan, thanks to the superior density of the tissue, can last 6-8 years or more, developing a noble patina in the process. A calf with vegetable tanning, especially if exposed to sweat and humidity, evolves chromatically in the first 12-18 months, while maintaining structural integrity for 4-6 years. Milano Straps offers an 18-month warranty on custom straps made by the Casati Milano atelier.
