Strap for Villeret Carrousel Phase de Lune Platinum

The Blancpain Villeret 6622L-3431-55B features a lug width (also called ansa width) of 23mm. This is an uncommon specification in contemporary watchmaking, requiring manual verification with a digital calliper by measuring the distance between the lugs. Standard strap suppliers rarely stock 23mm widths, making bespoke artisanal straps the most appropriate solution.

For the Villeret 6622L-3431-55B in platinum, we recommend dark brown alligator or cognac-coloured shell cordovan. Alligator emphasises the watch's formal restraint, whilst cordovan — with its construction density and natural patina development — creates temporal synergy with platinum: both materials evolve gracefully through years of wear. Vegetable-tanned calf leather offers a warmer, more versatile middle ground.

Changing the strap requires a specialised springbar remover tool and extreme care to avoid damaging the lugs. Use the flattened end of the tool to depress the springbar from the opposite side, remove the lug pin, then repeat on the other side. Position the new strap so its holes align with the pins, then reinsert the springbars ensuring they seat fully. Given the Villeret's value, professional service from a specialist atelier is strongly recommended.

Yes, provided they conform to the exact 23mm lug width specification. An artisanal 23mm strap from specialists such as Casati Milano is fully compatible. Always verify that the strap respects precise dimensions and that thickness does not create excessive friction with the case body. For noble leather straps, avoid industrial adhesive solutions and insist on saddle stitching.

An artisanal strap in noble leather — alligator, shell cordovan, vegetable-tanned calf — typically lasts 8–12 years with routine care. Cordovan, owing to its density, may exceed 15 years. Longevity depends on usage patterns: daily wrist wear shortens life compared to occasional wear. Exposure to moisture, direct heat, and perspiration accelerates ageing. Gentle periodic cleaning and leather-specific conditioning products significantly extend lifespan.
