Strap for Tourbillon Bi-Cylindrique White Gold

The Montblanc Villeret 106494 features a lug width of 19 millimetres. This measurement is determined by the geometry of the 47mm white gold case and its integrated lugs. To verify correct strap compatibility, measure the internal space between the two lugs: it must be precisely 19mm. Any discrepancy, even of a few tenths of a millimetre, would generate instability and unacceptable aesthetic results.

Alligator represents the most natural stylistic choice: the fine grain and planarity of the leather amplify the architectural elegance of the white gold case. Tones such as brun-cacao or warm cognac dialogue perfectly with the yellow of 18-carat gold. A refined alternative is vegetable-tanned calf, which develops patina over time, creating unique texture and paralleling the noble aging of white gold. Both materials require regular maintenance but offer timeless beauty.

The integrated lugs on the Villeret 106494 are removed using a precision tool: a spring bar tool or a specialised lug remover. Locate the micro-grooves in the lug housing and apply controlled pressure to extract the pin. Next, insert the new strap, align the pin and fasten with precision. It is strongly recommended to entrust this operation to a Montblanc professional or an experienced watchmaker to avoid damage to the white gold case, which is particularly sensitive to scratching during this procedure.

Yes, quality aftermarket 19mm straps are perfectly compatible with the Villeret 106494. However, it is essential to verify that the strap is specifically dimensioned for this lug width and that the attachment pins have the same diameter as the original Montblanc fittings. Specialised brands such as Milano Straps produce custom-made straps that guarantee precise fitting and high-quality materials, often superior to generic aftermarket offerings.

Durability depends on frequency of use, climatic conditions and leather type. Premium alligator or calf, used daily under moderate conditions, typically lasts between 3 and 5 years before requiring complete replacement. The white gold case, being subject to no natural wear like leather, remains intact indefinitely. Regular maintenance (cleaning with cloth, conditioning with appropriate creams, avoiding prolonged water exposure) significantly extends strap life, transforming it into part of the Villeret ownership experience.
