Strap for Villeret Chronographe Flyback Pulsomètre Red Gold / Enamel

The lug width of the Blancpain Villeret 6680F-3631-MMB is 23mm. This lug width is the standard for watches with a 43.60mm diameter in this category. To verify strap compatibility, you must measure the internal space between the two lugs: 23mm is the distance from inner edge to inner edge, measured perpendicular to the bar-clasp axis.

For the red gold Villeret 6680F-3631-MMB, we recommend alligator straps with vegetable tanning in brown tones (cognac, tobacco) or black. Alligator respects haute horlogerie tradition and its regular texture creates contrast with the satin case. Alternatively, dark brown or black calf leather with a lined grain offers a more contemporary aesthetic whilst maintaining elegance. Avoid very light leathers, which do not dialogue well with aged rose gold.

To change the strap, position the watch case downwards. Use a dedicated tool to remove the spring bars or a small flat blade: gently press the bar from one side while extracting the lug from the old strap. Once both lugs are free, insert the new bars into the new strap and reset the axes into the case lugs. Ensure the bars are firmly secured to prevent accidental watch drops.

Yes, any strap in 23mm lug width is compatible with the 6680F-3631-MMB, regardless of brand. However, for a chronograph of this category we recommend straps crafted with premium leathers (alligator, calf, shell cordovan) and from specialised ateliers. A low-end strap risks compromising the aesthetic and tactile experience of the watch. Always verify that the strap is fitted with compatible bars (1.5mm standard diameter) and that thicknesses adapt to the lugs.

A quality leather strap (alligator, calf with vegetable tanning) typically lasts 3-5 years with daily wear. Longevity depends on climate (humidity and extreme temperatures accelerate wear), frequency of wear, and maintenance. Vegetable-tanned leathers develop natural patina but age more visibly than chrome-tanned ones. Casati Milano guarantees artisanal straps for 18 months against manufacturing defects; replacement due to natural wear is considered ordinary maintenance.
