De Ville 4800.50.01— lug 20mm

The lug width of the De Ville 4800.50.01 is 20mm, measured internally from one attachment to the other. This dimension is critical to ensure perfect fit for any strap. Milano Straps provides 20mm straps with manufacturing tolerance below 0.5mm to ensure stability without angular oscillation.

Vegetable-tanned alligator is the ideal material for this dress watch, thanks to its regular texture and fine grain that complements the sobriety of the case. Elegant alternatives are shell cordovan (which develops a rich patina over time) and vegetable-tanned calf leather for those seeking less formality. Tactical silk NATO is perfect for daily versatility without losing elegance.

Strap replacement requires a spring bar tool to compress the internal springs of the lugs. Insert the flat tip of the tool into the lug slot, gently compress until you feel the spring release click, then slide the old strap away. Repeat for the other lug. Position the new 20mm strap and release the springs. If you are not experienced, the strap change service is available at the Casati Milano atelier by appointment.

A 20mm strap is generic for any watch with an identical lug width; however, the total strap length is constructed based on average wrist circumference. The De Ville has a specific case length that affects the proportion. Milano Straps creates straps with customizable lengths, so always verify compatibility with your watch.

A vegetable-tanned alligator strap lasts an average of 3-5 years of daily use, extendable to 7-8 years with occasional wear. Shell cordovan, thanks to the fibrous structure of the material, can last up to 10 years. Calf leather has a lifespan of 2-4 years depending on sun exposure and humidity. Milano Straps offers an 18-month warranty on all artisanal straps made at the Casati Milano atelier.
