Frequently asked questions

What is the exact lug width of the Montblanc Star 107072?

The Montblanc Star 107072 features a lug width of 19mm, an intermediate dimension that requires purpose-made straps. This size does not correspond to the most common commercial standards (18mm or 20mm), so it is essential to verify compatibility before purchasing an aftermarket strap.

Which type of strap pairs best with the Montblanc Star 107072?

The classical 39mm proportion and formal character of the case suggest fine leather straps: alligator for formal occasions, vegetable-tanned calf for daily wear. For sporty versatility, a vertical-striped NATO strap maintains the design's severity without compromising durability.

How do I change the strap on the Montblanc Star 107072?

Using a specialised spring bar tool, position the watch on a protective pad, then gently extract the lugs one side at a time. Never force: the lugs on the 107072 fit snugly. After removing the old strap, thread the new strap through the lugs in reverse order. A repair atelier or expert can complete the operation in minutes.

Can I use an aftermarket strap compatible with the Montblanc Star 107072?

Yes, provided the lug width is certified at 19mm. Artisanal straps offer superior colour and material freedom over original options. Ensure the strap does not have excessively thick edges at the lug attachment, otherwise the lugs may not slide smoothly into the seat.

What is the lifespan of a leather strap for the Montblanc Star 107072?

A premium leather strap (alligator, quality calf) typically lasts 3 to 5 years of daily wear, depending on humidity and cleaning frequency. Vegetable-tanned leather develops a natural patina over time, increasing aesthetic appeal whilst requiring regular maintenance. A cotton NATO strap lasts longer, up to 7–8 years.
