Strap for ExoTourbillon Chronographe White Gold / Grey

The Montblanc Villeret 109150 features a lug width of 19 millimetres. This measurement is specific to maintaining proper visual proportions with the 47mm white gold case. To verify your strap is compatible, measure the distance between the two attachment points on the lugs: this measurement must be exactly 19mm.

For this white gold model, we recommend alligator straps in pearl grey or champagne to enhance the luminosity of the case, or shell cordovan in burgundy-brown for a versatile option. In vegetable-tanned calf, shades of hazelnut and beige develop a patina that evolves over time. We advise against NATO and rubber straps, which conflict with the watch's aesthetic authority.

To change the strap on a Montblanc Villeret, remove the spring bar connecting the lug to the case using an appropriate tool (spring bar tool). Press downward on one end of the bar to extract it, then repeat on the other side. Align the new strap's holes with the spring bar and slide the bar into the lugs until it clicks into place. Ensure the spring bar is secure on both sides before wearing the watch.

Yes, you may use quality aftermarket straps provided they have a 19mm lug width. Milano Straps offers artisanal straps in alligator, calf, shell cordovan, and rubber specifically sized for this measurement. Artisanal quality ensures precise fit and superior longevity compared to generic straps. You can also request customisations through the Casati Milano atelier.

A quality artisanal leather strap, especially in alligator, shell cordovan, or vegetable-tanned calf, typically lasts 3-5 years with daily wear, or 5-8 years with occasional use. Durability depends on humidity exposure, skin transpiration, repetitive movements, and maintenance. A vegetable-tanned strap develops a patina that improves over time, whilst the wrist area naturally wears. A well-crafted artisanal strap can be refinished at least once during its lifespan, further extending its functionality.
