Strap for Villeret 8 Jours White Gold

The lug width of the Blancpain Villeret 6630-1531-55B is 23mm. This measurement represents the internal space between the two strap attachment points on the case. Accurate measurement is essential: position a ruler perpendicular to the lugs; a tolerance of ±0.3mm is acceptable for proper strap fit.

For the Villeret 6630-1531-55B, alligator leather, shell cordovan, or vegetable-tanned calf leather are optimal choices. American alligator represents the natural formal selection due to its delicate grain and tonal neutrality with white gold. Shell cordovan offers superior structural durability for daily wear, whilst vegetable-tanned calf develops natural patina that creates a unique personal narrative over time.

To change the strap, remove the lug pin using a dedicated spring bar remover tool. Position the watch on a stable surface, locate the small hole on the lug, gently insert the tool to compress the internal spring mechanism, then extract the pin. Repeat on the opposite side. Insert the new strap by positioning the pin in the lug attachment and ensuring the spring mechanism clicks securely into place.

Yes, third-party aftermarket straps compatible with the 23mm lug width are suitable. Milano Straps offers a comprehensive selection of artisanally crafted leather straps in premium materials (alligator, shell cordovan, calf leather) compatible with this specific lug width. It is essential to verify that the strap meets elevated construction standards to ensure durability and comfort.

Leather strap longevity depends on material quality, frequency of use, and maintenance practices. A premium leather strap (alligator, shell cordovan) may last 5-10 years with regular use if properly maintained. Vegetable-tanned leather develops natural patina that represents positive aesthetic ageing. Milano Straps provides an 18-month warranty on manufacturing defects. Protect the strap from excessive moisture and prolonged sun exposure to preserve structural integrity.
