Strap for Villeret Manuelle Piece Unique Grand Feu Men with Lunch

The lug width of the Blancpain Villeret 6615C-3631-55B - 2 is 23mm, measured from lug to lug. This dimension is specifically calibrated to the 45mm case geometry to maintain optimal proportions. We recommend verifying compatibility by measuring the internal space between the lugs: the strap should insert smoothly with a tolerance of ±0.5mm.

For a rose gold Villeret, vegetable-tanned alligator is the most coherent choice: its natural grain and developing patina create an aesthetic narrative parallel to the gold's oxidation. Alternatively, dark calf box leather (cognac or tobacco brown) offers sobriety and smooth texture, while shell cordovan represents a rare but exceptional choice for those seeking noble sheen and superior durability.

Strap replacement requires a precise spring bar tool (1.5mm diameter) to compress the elastic pins at the lug ends. Gently insert the tool into the lateral spaces of the lug attachment, lift the pin, and slide the old strap away. Repeat on the other side. The new 23mm strap must insert smoothly but without play: if resistance occurs, verify that the lug is positioned correctly between the case terminals.

Yes, any strap with 23mm lug width (measured lug-to-lug) is compatible with the Villeret 6615C-3631-55B - 2, provided the construction quality matches the watch's value. We recommend structured leathers (alligator, calf box, shell cordovan) rather than synthetic materials to maintain aesthetic coherence. Custom-made straps allow control over thickness, texture, and finish according to personal preference.

A superior-quality leather strap (alligator, calf box, shell cordovan) with proper care lasts 4-7 years under daily wear. Longevity depends on sun exposure, humidity, and frequency of use. Vegetable-tanned leather develops a patina that increases visual character over time. Shell cordovan, being more robust, can exceed 7-8 years.
