Strap for Villeret Ultraplate Automatique White Gold / White

The lug width of the Blancpain Villeret 6223-1127-55 is 20 millimetres. This measurement represents the distance between the inner points of each lug and is the fundamental parameter for selecting compatible straps. A 20mm lug width is the classical standard for 38-millimetre cases with vintage-forward proportions, such as those found on the Villeret.

For a 18-carat white gold case such as the 6223-1127-55, we recommend southern alligator (niloticus) with formal tanning: its compact grain, natural patina, and neutral tonalities (black, dark brown, slate grey) do not compete with precious metal but rather enhance it. Alternatively, vegetable-tanned calf leather offers a more refined interpretation, developing a golden patina that ages alongside the gold. Silk-based NATO in natural cotton represents the contemporary choice for those seeking to balance formality with daily practicality.

The Blancpain Villeret 6223-1127-55 uses standard springbars to secure the strap. To replace it: remove the current strap using a springbar tool (available from specialist watchmakers) by applying gentle pressure to the internal spring at each attachment point. Insert the new 20mm strap above the springbar in neutral position, then position the spring. Ensure both attachments are secured firmly before wearing. We recommend entrusting this operation to a professional watchmaker to avoid damage to the white gold case.

Yes, the 6223-1127-55 is fully compatible with quality aftermarket straps measuring 20 millimetres in lug width. However, since the case is in 18-carat white gold and the Blancpain caliber 1150 manual movement represents a milestone in Swiss manufacture, it is advisable to select straps constructed with comparable artisanal care. Leathers such as Nile crocodile, French vegetable-tanned calf, or heavyweight cotton ensure durability and aesthetic proportion coherent with the watch's value. Avoid economical leathers: they will age poorly and betray the intrinsic quality of your timepiece.

Longevity depends on leather type and usage patterns. A quality Nile alligator strap with formal tanning typically lasts 3–4 years of daily wear before showing significant signs of deterioration (thinning, cracking). Vegetable-tanned calf leather has similar durability, though the patina it develops during ageing makes it aesthetically more compelling over time. A heavyweight cotton NATO typically resists 2–3 years. For the 6223-1127-55, investing in a bespoke artisanal strap from Casati Milano guarantees 18 months' warranty against manufacturing defects and the possibility of maintenance or deployant buckle replacement without additional construction costs.
