Strap for Villeret Tourbillon Squelette 8 Jours Red Gold

The lug width is exactly 20 millimetres. This precise dimension defines the aesthetic dialogue between the rose gold case and the wrist. To verify, measure the space between the two metal lugs of the case (between 12 and 6 o'clock) with a calliper. No approximation is acceptable: an incorrect strap destroys the visual balance.

Genuine alligator is the most congruent solution: the natural leather texture harmonises with the case. Alternatively, vegetable-tanned calf develops character and patina over time. A moulded rubber strap maintains sporty rigour without betraying the dress nature of the Villeret. Avoid NATO: it contrasts fundamentally with the refined elegance of your timepiece.

Strap change is performed via the spring bars. Use a dedicated extraction tool to gently push one spring bar inward, freeing the strap from the lower lug, then repeat for the upper lug. Insert the new strap ensuring the spring bars fit perfectly into the lugs. Verify that the case sits perfectly horizontal on the wrist.

Yes, provided it is crafted by specialised artisans and strictly respects the 20mm dimension. Hand-assembled straps guarantee perfect geometric adherence and absence of play. Materials must be superior quality: genuine alligator, vegetable-tanned calf, or moulded rubber. Blancpain imposes no technical restrictions, provided the strap is constructed with equivalent meticulousness.

A leather strap (alligator or calf) lasts approximately 4–8 years with moderate daily wear. Longevity depends on sun exposure, humidity and frequency of use. Natural leather patinates and darkens with age: this is a desirable character, not a defect. A rubber strap typically lasts longer (8–10 years) with lesser aesthetic variability. Casati Milano guarantees 18 months against manufacturing defects.
