Strap for Villeret Tourbillon Minute Repeater Automata Red Gold / Opaline

The lug width of the Blancpain Villeret 6033-3642-55 is 20 mm. This dimension is proportionate to the 37.50 mm case diameter and ensures balanced aesthetic proportions on the wrist. The measurement is taken by positioning a digital calliper between the two lugs at their innermost point, where the strap attaches to the case.

For this rose gold Villeret, the most suitable materials are French Taurillon calf leather with vertical grain finish (which complements the patina of rose gold), alligator in cognac or dark brown, and shell cordovan in burgundy. The leather must be sufficiently thick (1.4–1.6 mm) to support the weight of rose gold without sagging. A vegetable-tanned leather strap offers the opportunity to develop a natural patina parallel to that of the case itself, creating aesthetic harmony over time.

Strap replacement requires two specific tools: a spring bar tool (extractor) and a small flathead screwdriver. Position the watch on a soft surface to avoid scratching the rose gold. Insert the spring bar tool into the tiny lateral hole of the spring pin, apply gentle downward pressure to release the pin, then slide the old strap out of the lugs. Repeat the procedure with the new strap. Ensure the pin clicks fully into place — it must remain invisible within the case.

Yes, provided the strap is of artisanal quality and has a 20 mm lug width. An aftermarket strap crafted from premium leather or technical rubber often offers greater aesthetic versatility than the original Blancpain model. The choice depends on usage: a Taurillon calf strap is ideal for formal occasions, whilst a heavyweight nylon NATO strap is perfect for daily wear. Ensure the strap thickness (approximately 3–4 mm in the body) is proportionate to the case diameter.

A leather strap of artisanal quality, crafted from noble leather (alligator, shell cordovan, or Taurillon calf), typically lasts 4–7 years with moderate daily use. Critical factors include exposure to perspiration, moisture, and UV radiation. A strap cared for meticulously — dried after water contact and stored away from direct sunlight — may last up to 10 years. Periodic maintenance (treatment with natural beeswax every 6–12 months) significantly extends strap lifespan and encourages development of a fascinating natural patina.
