Strap for Villeret Quantième Annuel GMT White Gold / Opalin Flinqué

The Blancpain Villeret 6670-1542-55B is equipped with 22-millimetre lugs. Blancpain selected this dimension to maintain visual balance between the 40mm case diameter and wrist ergonomics. Always verify the width by removing the original strap: lug width is measured from the end of one lug to the start of the other.

For the white gold 18-carat Villeret, Milano Straps recommends Mississippi alligator in midnight blue or dark brown. Alligator offers fine natural grain, fibre density that supports thin gauge construction, and a golden patina that harmonises perfectly with white gold. Alternatively, burgundy or black shell cordovan for those seeking extraordinary durability and a lustre that emerges with ageing.

The process requires specific tools: a spring bar tool to extract the lugs, and precision. Position the watch on a soft mat, locate the tiny hole at the lug end, insert the spring bar tool to compress the internal spring, withdraw the lug with lateral motion. Repeat for the opposite end. For new strap installation, reverse procedure: compress the spring, insert the lug, release gradually whilst verifying engagement. If inexperienced, entrust this to Casati Milano.

Yes, provided the strap is manufactured for 22mm lugs. Milano Straps offers handcrafted leather straps in vegetable-tanned leather, alligator and shell cordovan specifically calibrated for this width, with adjustable passants in gold, silver or steel according to desired aesthetics. Every strap carries an 18-month manufacturing defect warranty.

A quality-manufactured alligator strap, with appropriate tanning, resists 4–6 years in daily use. Shell cordovan, thanks to the fibre density of equine leather, can reach 7–8 years. Vegetable-tanned calf lasts 2–4 years depending on sun exposure and humidity. The primary variable is maintenance: natural water-repellent protection applied every 6–8 months substantially extends strap life.
