Montblanc
Star 106466— lug 19mm

The Montblanc Star 106466 features a lug width of 19mm. This standard measurement represents the distance between the strap attachment pins on the case lugs. Measurement is performed by placing a digital calliper between the two internal pins without forcing, ensuring precise compatibility with artisanal straps.

For the 106466, we recommend straps in alligator leather with vegetable tanning or high-quality calf leather. Alligator offers pronounced natural grain and rich patina development over time, whilst vegetable-tanned calf provides subtle texture and develops predictable natural patina. Both materials enhance the refined aesthetics and geometric architecture of the case, maintaining stylistic coherence with the model's sober German identity.

Changing the strap on the 106466 requires a spring bar removal tool. Position the watch on a soft surface to avoid scratches. Gently insert the tool into the side hole of the spring bar, press to compress the spring, and slide the pin out of the lug. Repeat on the opposite side. For installing the new strap, reverse the procedure ensuring the pin is fully inserted and the spring bar is firmly positioned.

Yes, any artisanal strap with a 19mm lug width is fully compatible with the 106466. High-quality aftermarket straps enable aesthetic and functional customisation, from premium leathers to technical fabrics, without compromising case integrity. Always verify that the strap width corresponds exactly to the specified 19mm.

The lifespan of a leather strap depends on usage intensity, climatic conditions and material quality. A well-maintained alligator or artisanal calf strap typically lasts 5-8 years with daily use, developing desirable patina over time. Prolonged exposure to water, perspiration and UV rays accelerates ageing. Vegetable tanning, whilst requiring greater care, ensures superior longevity due to more robust molecular structure.
