The Villeret 6615-3616-55B - 3, seen from the bench

The Blancpain Villeret 6615-3616-55B-3 is a contemporary watchmaking achievement featuring the manual-wound Blancpain 15B calibre in a 45mm rose gold case. The Villeret family, established in 1992 as tribute to the Vallée de Joux manufacture, embodies minimalist aesthetics with no concessions to trends. This model features a skeletonized caseback showcasing the movement's engineering, paired with essential dial lines, baton indices, and Dauphine hands. The distinctive 23mm lug width requires a bespoke strap solution, reflecting the proportional balance between the generous case diameter and the wearer's wrist.

Frequently asked questions

What is the lug width of the Blancpain Villeret 6615-3616-55B - 3?

The lug width of the Blancpain Villeret 6615-3616-55B - 3 is 23mm. This is a non-standard measurement that requires custom-made straps. To verify compatibility, measure the distance between the lugs at the widest point using callipers: if you read 23mm ±0.5mm, your strap is compatible.

What type of strap is most suitable for the Blancpain Villeret 6615-3616-55B - 3?

For a 45mm Villeret in rose gold, alligator leather with vegetable tanning represents the most elegant choice: the natural texture dialogues perfectly with the gold reflections, and the patina it develops over time evolves in harmony with the case oxidation. Alternatively, fine-grain French calf or shell cordovan offer versatility whilst maintaining high quality standards.

How do you change the strap on the Blancpain Villeret 6615-3616-55B - 3?

Strap replacement is accomplished via spring bar: gently remove the lateral spring with a dedicated tool (pin or dedicated instrument), slide the old strap out of the lug, insert the new strap, and reposition the spring. It is a straightforward operation that can also be entrusted to a watchmaker for precision and protection of the case from potential damage.

Are there aftermarket straps compatible with the 23mm lug width?

Yes. MilanoStraps offers a collection of artisanal 23mm straps manufactured from premium leather: alligator, vegetable-tanned calf, shell cordovan and structured rubber. Each strap is custom-made to ensure millimetre-precise compatibility. Alternatively, you can request a bespoke service at the Casati Milano atelier for complete personalisation.

How long does a leather strap last on a watch with daily wear?

A premium artisanal leather strap subjected to regular use on a 45mm watch such as the Villeret has an average lifespan of 3-5 years before replacement is required. Shell cordovan and vegetable-tanned leather age more gracefully, developing patina rather than degrading. Regular maintenance (cleaning, conditioning) significantly extends the strap's lifespan.
