Strap for Villeret Chronographe Flyback Pulsomètre Red Gold / Enamel

The lug width of the Blancpain Villeret 6680F-3631-55B is 23mm. This is a non-standard dimension characteristic of this 43.6mm case diameter. Always measure the internal space between the lugs before ordering a strap, using a calliper or consulting the official Blancpain documentation.

For this red gold 18-carat chronograph, we recommend straps in dark brown shell cordovan or black alligator with vegetable tanning. Cordovan develops a patina that dialogues organically with the ageing of red gold, whilst black alligator emphasises formal elegance. A matching red gold deployant clasp ensures complete aesthetic coherence. Contact Casati Milano for bespoke consultation.

Strap replacement requires a spring bar tool to remove the elastic pins securing the strap to the lugs. Position the tool in the pin slot, apply gentle lateral pressure and slide the pin out. Proceed carefully to avoid scratching the red gold case. If inexperienced, entrust the operation to a professional watchmaker or Casati Milano's service.

Yes, provided the strap is specifically dimensioned for 23mm lugs. Many universal straps are incompatible with this non-standard size. Milano Straps offers a wide selection of bespoke and ready-made straps in 23mm, crafted with noble materials such as cordovan, alligator and calf leather. Always verify technical specifications before purchase.

A high-quality shell cordovan strap lasts 8–12 years with appropriate maintenance (twice-yearly conditioning with vegetable waxes). Vegetable-tanned alligator reaches 8–10 years. Textured calf, a more delicate material, requires replacement after 5–7 years of regular wear. Casati Milano's warranty covers 18 months against manufacturing defects, independent of natural leather wear.
