Frequently asked questions

What is the lug width of the Blancpain Villeret 6615C-3631-55B - 1?

The lug width is 23mm. This non-standard measurement is specifically calculated to balance the 45mm rose gold case diameter and the overall aesthetic composition. To verify compatibility, measure the internal distance between the two lugs at the point where the strap's passant slots in.

Which strap material is most suitable for the rose gold Blancpain Villeret?

Alligator leather remains the natural choice: its regular grain texture and developing patina dialogue perfectly with the nobility of rose gold. For greater versatility, fine-grained calf leather (Gobelins) permits rotation between formal and business-casual styles. Shell Cordovan represents a compromise between noble patina and structural durability, ideal if the watch is worn as a functional instrument.

How do I change the strap on a 45mm watch with a 23mm lug width?

Obtain a dedicated spring bar removal tool. Position the watch on a flat surface, insert the tool's tip into the small spring bar slot, and gently push to free the old strap. Repeat on the other side. To fit the new strap, align the passant with the lugs and push the spring bar until you hear a click. Verify complete insertion.

Can I use an aftermarket strap compatible with other watches on this Villeret?

Only if specifically dimensioned for 23mm lug width. The 23mm width is non-standard in the market: most aftermarket straps are produced for 20mm, 22mm, or 24mm lugs. Using a poorly calibrated passant causes slippage, spring bar wear, or lug damage. We recommend custom straps or those verified for exact compatibility with your reference.

How long does a natural leather strap last on an elegant dress watch like the Villeret?

An alligator strap of quality, worn daily, lasts between 3 and 5 years before replacement is required. Shell Cordovan can last up to 7-8 years due to its structural resistance. Lifespan depends on wear frequency, humidity exposure, maintenance care (occasional cleaning, drying), and climate conditions. Vegetable-tanned leather significantly increases longevity compared to chrome tanning.
