Strap for Villeret Tourbillon Volant Une Minute 12 Jours Platinum

The lug width of the Blancpain Villeret 66240-3431-55B is 23 millimetres. This measurement is determined by the 42mm case geometry and ensures the proportional harmony of the design. To verify strap compatibility, measure the distance between the two lug pins with a digital calliper: it must be exactly 23mm.

For the platinum Villeret, cognac-brown alligator is the classical choice, accentuating the metal's cool luminosity. However, vegetable-tanned calf leather offers refined subtlety and the possibility of ageing in harmony with the platinum's patina. Shell cordovan provides superior durability and incomparable tactile density. The choice depends on your lifestyle and frequency of wear.

To change the strap, remove the lug pins using a spring bar tool or consult a professional. Insert the tool's tip into the small lateral hole of the lug seat, compress the internal spring slightly, and extract the pin. Repeat on the opposite side and replace with the new strap. Ensure the pins are the correct length for the 23mm lug width.

Yes, any strap fitted with pins suitable for 23mm lugs is compatible with the Villeret 66240-3431-55B. However, we recommend selecting reputable or artisanal manufacturers such as Casati Milano, which guarantee build quality, noble materials, and finishing worthy of the timepiece's prestige. A mediocre strap compromises the aesthetic and functional experience of a horological masterpiece.

Leather strap durability depends on the tanning method and usage conditions. An alligator strap typically lasts 5-7 years with daily wear. Vegetable-tanned calf leather easily reaches 8-10 years. Shell cordovan, owing to its structural density, can last beyond 12 years. Exposure to perspiration, humidity, and UV rays accelerates wear. Proper maintenance and rotation with other straps significantly extend the strap's lifespan.
