Strap for Villeret Tourbillon Minute Repeater Automata White Gold / Opaline

The lug width of the Blancpain Villeret 6033-1542-55 is 20 millimetres. This dimension determines strap compatibility: it is essential to verify that the chosen strap is specifically designed for 20 mm lugs, as straps of 18 mm or 22 mm would not adhere correctly to the case.

Alligator represents the pinnacle choice for this dress model: its characteristic grain and evolved patina reflect the refinement of the white gold case. French calf with a lined finish is a versatile and durable alternative. FKM rubber is contemporary and functional, whilst NATO is inadvisable as its sport-oriented vocation contradicts the classical identity of the Villeret.

The strap is changed using a specialised tool (spring bar tool) to extract the spring bar that secures the strap to the case lugs. Position the tool in the lug hole, apply gentle pressure to compress the spring, then extract the old strap. Insert the new strap into the space left vacant, reinsert the spring bar and verify that it is firmly locked in place. It is advisable to consult a professional watchmaker if you lack experience.

The Villeret 6033-1542-55 comes from the factory with an original Blancpain alligator strap. However, the standard 20 mm lug width permits the use of quality aftermarket straps: what matters is that they are crafted by artisans experienced in haute horlogerie and that they respect the aesthetic proportions of the model. Casati Milano offers handmade 20 mm straps that are perfectly compatible.

A quality leather strap (alligator, calf, vegetable-tanned) on a daily-worn wristwatch has an average lifespan of 3–5 years, depending on usage and care. Leather is a living material that ages, developing patina but also fragility in the bending and stress points. Casati Milano guarantees handmade straps for 18 months against manufacturing defects, and recommends seasonal rotation to prolong the useful life of the leather.
