Strap for De Ville Tourbillon White Gold / Silver

The lug width is 18mm. This dimension represents the distance between the centers of the attachment pins (lugs). It is a rare and refined width, calibrated to the proportional ratio with the case diameter of 38.70mm. Always verify the measurement with a caliper positioned from lug to lug before purchasing a strap.

Black alligator in vegetable tanning is the most authentic choice for this dress watch. It offers formal elegance, a tight grain texture, and the ability to develop a caramelized patina over time. Alternatively, black or navy blue shell cordovan ensures natural water resistance and a deep luster that intensifies with aging. For those seeking versatility, fine-grained Italian calf leather offers immediate softness and a uniform appearance.

The De Ville uses a pin attachment system (lugs). Using a spring bar tool or a small flathead screwdriver, position the lever under the pin and gently push outward until the pin exits the case. Repeat on the other side. Once the pins are freed, slide off the old strap and insert the new one, reintroducing the pins until they snap into place. If you prefer security and precision, Casati Milano atelier can perform the change.

Yes, any strap with an 18mm lug width is compatible. Ensure the width is exactly 18mm (measured between the attachment points). Handcrafted straps from milanostraps.it are custom-built for this width, with customization options in leather, color, and stitching to ensure maximum aesthetic fit to your De Ville.

Durability depends on the material and usage. A quality vegetable-tanned alligator lasts 3-5 years with daily wear, developing a desirable patina. Shell cordovan, more durable, reaches 5-7 years. Italian calf leather, more delicate, has a lifespan of 2-4 years. Direct sun exposure, intense perspiration, and humidity accelerate wear. Casati Milano's 18-month warranty covers manufacturing defects; aesthetic aging is a natural part of the patination process.
