Strap for Villeret Manuelle Piece Unique Grande Décoration / White Enamel

The lug width of the Blancpain Villeret 6615-3631-55B is 23 millimetres. This measurement is determined by the proportions of the 45-millimetre case and the configuration of the exhibition caseback. Measurement must be taken from the inner point of the left lug to the inner point of the right lug, perpendicular to the lugs.

For a Villeret in 18-carat red gold, we recommend natural alligator (medium grain) which enhances the golden tone of the case, or vegetable-tanned calf leather with developed patina in dark brown or burgundy tones, creating sophisticated contrast. Structured FKM rubber is the modern alternative for those desiring visual separation between case and strap. We advise against NATO straps, which flatten the proportions of a 45-millimetre case.

Strap change requires specific tools (spring bar tools and extractors) and must be performed carefully on a skeletonised movement like the caliber 15B. We recommend the Casati Milano service: you can select the leather directly in our Milan atelier, follow the crafting process via WhatsApp, and receive your strap with an 18-month manufacturing warranty. For self-installation, ensure your new strap is pre-drilled for 23-millimetre lugs.

Yes. All artisanal straps with 23-millimetre lug width are compatible with the Blancpain Villeret 6615-3631-55B. MilanoStraps offers a complete collection of 23mm straps in alligator, calf, shell cordovan, and rubber, crafted custom-fit with spring bars and keepers proportioned to the case.

A quality leather strap (alligator in vegetable tanning or vegetable-tanned calf) lasts approximately 4 to 7 years under regular use and normal climate variation. On a Villeret 6615-3631-55B, which is a conservative wrist instrument, durability tends toward the upper range. The patina that develops over time increases aesthetic value. Casati Milano provides an 18-month manufacturing warranty and support for replacement with spare spring bars.
