Strap for Villeret 8 Jours Manuelle Red Gold / Black Enamel

The lug width of the Blancpain Villeret 6614-3637-55B is 23mm, which is an uncommon standard in the watch market. This dimension is specific to this model and requires custom-made straps or proprietary solutions. It is essential to verify this measurement precisely using a digital calliper, as straps of 22mm or 24mm would not fit correctly into the case lug slots.

For the Villeret 6614-3637-55B, alligator leather (French or American) remains the dominant choice owing to its regular geometric grain that accentuates quadrant symmetry and develops noble patina over time. European vegetable-tanned calf leather offers a sophisticated alternative with organic texture. Japanese shell cordovan introduces caramel tones that create a fascinating contrast with rose gold. For daily wear, a black vulcanised rubber strap with rose gold deployante combines practicality and elegance.

To change the strap on the Villeret 6614-3637-55B, you must remove the spring bars that connect the strap to the case lugs. Use a dedicated spring bar removal tool to extract the bars. Once removed, gently slide the old strap out of the lugs and insert the new strap, respecting proper orientation. Reinsert the spring bars until they click into position. It is crucial not to force the bars in order to avoid damaging the lugs.

Yes, aftermarket straps compatible with the Villeret 6614-3637-55B can be used provided they strictly respect the 23mm lug width. High-quality artisanal straps such as those offered by Casati Milano guarantee dimensional precision, noble materials (alligator, calf, shell cordovan) and workmanship tailored to the watch's specifications. Quality aftermarket straps often offer aesthetic customisation (colour, texture, buckle) that increase the versatility of the timepiece.

The lifespan of a natural leather strap depends on usage and material. Alligator, shell cordovan and vegetable-tanned calf, if properly maintained, can last 5–8 years with daily wear. Natural leather ages and develops patina, which is a desirable characteristic among enthusiasts. Exposure to extreme temperatures, excessive humidity and perspiration accelerates wear. Casati Milano straps carry an 18-month warranty on manufacturing defects; longevity will depend on personal care and usage.
