Strap for Villeret Réveil GMT Stainless Steel / White

The lug width of the Blancpain Villeret 6640-1127-55B is 22 millimetres. This measurement represents the internal space between the two metal lugs on the case that accommodate the strap. To measure correctly, use a digital calliper and position it between the internal lug attachments, not on the external surfaces. Any strap you purchase must be specifically sized for 22 millimetres lug width.

Mississippi alligator with symmetrical broad grain is the traditional choice for the Villeret, thanks to its geometric texture that dialogues elegantly with the case's austerity. Alternatively, vegetable-tanned calf offers softness and develops an ennobled patina over time. Shell cordovan represents an excellent compromise between alligator durability and the velvety feel of calf. The choice depends on intended use: alligator for formal wear, calf for versatility, shell cordovan for timeless appeal.

The strap is attached to the case lugs through lateral passages. To remove it, locate the spring bars securing the strap—one on each side at the case shoulders. Using a specialised spring bar tool, gently push the bar in the direction away from the strap to release it. Remove the strap and repeat on the other side. To install the new strap, align the passages with the lugs, then reinsert the spring bars by applying even pressure until you hear a click. If unsure, consult an expert to avoid damaging the case.

Yes, a quality aftermarket strap is perfectly compatible with the Villeret, provided it respects the 22-millimetre lug width and its passages are correctly sized for the case lugs. An artisanal strap from a qualified maker—such as Casati Milano—guarantees noble materials, precise craftsmanship and finishes compatible with a luxury watch's aesthetic. Compatibility does not guarantee quality: always verify the strap is manufactured for this specific lug width.

The lifespan of a leather strap depends on material and usage patterns. Quality alligator can last 5–8 years with moderate daily wear, whilst calf and shell cordovan typically range between 3–6 years. Vegetable tanning tends to age more rapidly but aesthetically, developing patina and colour. Prolonged exposure to sunlight, moisture and perspiration accelerates wear. Casati Milano provides an 18-month guarantee on manufacturing defects and recommends periodic maintenance to extend strap life.
