Strap for Villeret Ultraplate Automatique 40mm Red Gold / Opalin / Diamond

The lug width of the Blancpain Villeret 6651-2987-55B is 22mm, which represents the distance between the two case attachments where the strap secures. This width is proportionate to the 40mm case diameter and ensures visual and structural balance. Accurate measurement with a digital calliper is essential when selecting an aftermarket strap to avoid lateral play or structural stress on the case.

For the Villeret, Mississippi alligator represents the optimal choice: the fine grain and naturally flat fibre allow refined construction with reduced thickness. Alternatively, vegetable-tanned calf leather creates a complementary material narrative with white gold, whilst shell cordovan offers characteristic density and natural lustre. Selection depends on use context and colour preference: midnight blue alligator for formal wear, burgundy calf for material warmth.

Strap replacement requires a dedicated spring bar tool and care to avoid scratching the white gold case. Place the watch on a soft surface. Locate the small elastic pin holding the lug in position, gently press it inward with the tool, and the lug slides free. Insert the new strap, aligning the 22mm pitch to the holes, and press until the safety detent clicks. For risk avoidance on white gold, Casati Milano offers in-atelier replacement service.

All straps with 22mm lug width are compatible with the 6651-2987-55B, regardless of manufacturer. Milano Straps offers an extensive selection of artisanal 22mm straps crafted from premium materials: alligator, vegetable-tanned calf, shell cordovan, wool merino NATO, butadiene rubber. Compatibility is guaranteed by lug width; stylistic choice depends on material, colour, and desired texture.

Leather strap longevity depends on daily wear, maintenance, and material quality. Premium-grade alligator in vegetable tanning, if protected from excessive perspiration and rotated seasonally, maintains structural integrity for 7–10 years. Fine calf typically endures 5–7 years under intensive use. Shell cordovan, owing to natural density, easily reaches 8–12 years. Casati Milano guarantees 18 months against manufacturing defects and offers restoration and refooting services to extend strap life over time.
