Strap for Villeret Demi-Fuseau Horaire Stainless Steel / White

The lug width of the Blancpain Villeret 6660-1127-55B is 22 millimetres. This dimension is determined by the linear distance between the two pins protruding from the case: always measure the functional void, not the total perimeter of the lugs. A 22mm aftermarket strap will fit without friction and without mechanical play.

For this model we recommend supreme quality niloticus alligator or vegetable-tanned calf leather. Alligator offers a symmetrical, natural texture that dialogues with the dial; vegetable-tanned calf develops a natural patina over time that narrates ageing. Avoid rubber or canvas straps, which contradict the formal identity of the Villeret.

Strap change occurs by removing the pins that connect the case to the lugs. Position the watch on a stable surface and use a dedicated spring bar tool to slightly compress the pin and extract the exhausted strap. Insert the new 22mm strap by aligning the holes, then reinsert the pin until you feel a click. Avoid hammers or excessive force.

Yes, any strap with a 22mm lug width is mechanically compatible. However, construction quality and material determine aesthetic cohesion with the watch. We recommend alligator, shell cordovan or fine calf to maintain the formal level of the timepiece. Avoid budget straps in synthetic leather, which age poorly.

A high-quality natural leather strap (alligator, vegetable-tanned calf) lasts 3-5 years with daily use, depending on climate, cleaning frequency and sun exposure. Vegetable tanning develops a natural patina that enriches the strap over time. With proper maintenance (occasional cleaning, storage in a dry environment), longevity extends. Casati Milano straps include an 18-month warranty against manufacturing defects.
