Strap for Villeret Quantieme Complet 8 Jours Red Gold / White / Bracelet

The lug width of the Blancpain Villeret 6639-3642-MMB is 23mm. This measurement represents the distance between the inner edges of the lugs and corresponds to the strap attachment point on the 42mm red gold case.

We recommend straps in dark brown or cognac alligator, or burgundy shell cordovan for the Villeret 6639-3642-MMB. These materials maintain aesthetic balance with the red gold case. For casual wear, vegetable-tanned calf leather or a grey NATO strap function excellently whilst preserving classical heritage.

Strap change on the Villeret 6639-3642-MMB is performed by removing the spring bars using a specialist lever tool. Position the watch face-down, compress the bar from the lower side and slide it horizontally. Once the bars are freed, insert them into the lugs of the new strap and reinsert them into the case. The procedure requires delicacy to avoid scratches on the red gold case.

Yes. The Blancpain Villeret 6639-3642-MMB is fully compatible with aftermarket straps fitted with 23mm lugs. Milano Straps offers a complete collection of bespoke artisanal 23mm straps in fine leather, with 18-month warranty on manufacturing defects.

A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) typically lasts 4–6 years with moderate daily wear. Durability depends on usage, maintenance (avoid standing water) and tanning type. Fine leather develops patina over time, becoming more beautiful with age. Replacement is straightforward and recommended every 5–7 years.
