Strap for Villeret Tourbillon 8 Jours White Gold / Opaline / Diamond

The lug width of the Blancpain Villeret 6025-1942-55B is 20 millimetres. This measurement is essential for aftermarket strap compatibility. You can verify it by placing a calliper in the internal lug seats: the distance must measure exactly 20 millimetres to ensure precise fitment without lateral play.

For the Villeret 6025-1942-55B, alligator is the most appropriate material, as it enhances the purity of white gold through tactile and visual contrast. Alternatively, vegetable-tanned calf develops a rich patina over time, whilst shell cordovan offers restrained lustre. For an elegant sportive approach, natural FKM rubber ensures comfort and robustness without aesthetic compromise.

The Villeret 6025-1942-55B strap is changed by removing the lugs. You must use a specific tool (spring bar tool) to compress the internal springs within the lugs and release them from the old strap seats. Subsequently, the new strap is inserted into the same seats until they click into place. We advise against forcing: slow, constant pressure is the correct method.

Yes, an aftermarket 20mm strap is completely compatible with the Villeret 6025-1942-55B, provided the lugs are identical to the original model. Compatibility is verified by correct lug width and mounting hole dimensions. Artisan-quality straps, such as those produced bespoke, guarantee manufacturing tolerances that exclude any movement during installation.

The lifespan of a leather strap depends on frequency of use, material, and tanning method. Vegetable-tanned alligator or quality calf can last 3–5 years with daily wear and regular maintenance (drying after moisture exposure, protection from direct sunlight). Shell cordovan, being more resistant, can extend to 6–7 years. A natural FKM rubber strap offers superior durability, up to 10 years.
