Strap for Villeret Ultraplate Automatique 40mm Stainless Steel / White Damier

The Blancpain Villeret 6651-1143-55B features a lug width of 22 millimetres. This measurement is taken between the two spring bars on which the strap sits. It is a classic standard width that provides access to an extensive selection of artisanal straps without requiring any structural modifications.

For the Villeret 6651-1143-55B, we recommend vegetable-tanned Tuscan leather in mocha, brown, or black tones, as these create perfect aesthetic contrast with the white dial and steel case. Alternatively, alligator or chromexcel calf offer additional prestige and develop beautiful patina over time. Your choice depends on usage: formal occasions suit leather, whilst daily wear permits heavy-cotton NATO fabrics.

Changing the strap on a Villeret 6651-1143-55B is straightforward: locate the spring bars on both sides of the case beneath the lugs, use a spring bar tool to gently depress the bar, remove the old strap, insert the new strap whilst aligning it with the holes, and release the bar. No case removal is required. We recommend consulting the official Blancpain manual for specific torque specifications and pressure guidelines.

Yes, any strap measuring 22 millimetres in width is fully compatible with the Villeret 6651-1143-55B. Artisanal straps crafted by Casati Milano or other reputable manufacturers are constructed to identical lug width standards and will fit perfectly. Always verify the width is precisely 22 mm before purchasing.

A quality vegetable-tanned leather strap, used moderately and maintained with care, typically lasts 3-5 years. Alligator and shell cordovan are significantly more durable, often lasting 7-10 years. Longevity depends on ambient humidity, frequency of wear, and leather quality. Casati Milano straps include a 18-month guarantee against manufacturing defects.
