Strap for Villeret Mouvement Inversé Serti Neige

The lug width of the 6616-9400-55B is 23 millimetres. This is a non-standard measurement, typical of the 43 mm Villeret models in white gold. Measure the internal distance between the two case lugs using a digital calliper. Precision is essential before ordering a compatible strap to ensure proper fit and visual harmony.

Alligator leather is the ideal choice for this model: its natural texture complements the polished white gold case and the Villeret's formal aesthetic. Vegetable-tanned calf leather offers excellent character development and patina formation over time. Shell cordovan represents the premium option for durability and subtle lustre. For versatility, a canvas NATO strap delivers practicality without aesthetic compromise. Recommended colours include dark brown, cordovan, black, and navy blue; avoid saturated hues.

To change the strap on the 6616-9400-55B, remove the spring bars connecting the strap to the case using a spring bar tool. Insert the flat end of the tool under each spring bar, apply gentle pressure to disengage the mechanism, and slide the bar outward. Repeat on the opposite lug. When installing the new strap, ensure the spring bars click firmly into the case slots with no lateral play. If unfamiliar with the procedure, consult a qualified watchmaker.

Yes, high-quality aftermarket straps compatible with 23 mm lugs are entirely suitable. We recommend artisanal leather straps in premium materials such as alligator, vegetable-tanned calf, or shell cordovan, or technical fabrics like FKM for tropical climates. Ensure the strap respects the proportions and finishing standards of a 43 mm white gold sports watch. Milano Straps stocks a curated selection of 23 mm straps specifically compatible with the Villeret.

Longevity depends on material, tanning process, and wear frequency. Vegetable-tanned alligator typically lasts 3–5 years of daily use, with potential extension through gentle care. Shell cordovan is more resilient, often lasting 5–7 years or longer. Vegetable-tanned calf averages 2–3 years. Manufacturing defects are covered under an 18-month warranty. Once worn, replacement is straightforward thanks to standard spring bar compatibility.
