FAQ
What is the lug width of the Montblanc Heritage 113780?
The Montblanc Heritage 113780 features a lug width of exactly 20 mm. This dimension is integral to the watch's visual proportions, harmonising the 42 mm case diameter with the strap attachment points. The spring bars have no lateral play, making precise compatibility with 20 mm straps essential.
Which strap material is most suitable for the Montblanc Heritage 113780?
We recommend <a href="/pages/termine-glossario/alligatore">alligator</a> leather or vegetable-tanned calf leather. Black or burgundy alligator emphasises the red gold and stainless steel combination in formal contexts. Cognac-toned calf, with its natural grain and developing patina, creates an intimate dialogue with the visible movement. For controlled sporting occasions, a canvas NATO strap imparts a vintage pilot chronograph character.
How do I change the strap on the Montblanc Heritage 113780?
Release the spring bars positioned at both strap attachment points. Using a dedicated spring bar tool or small flat screwdriver, compress the spring mechanism and slide the bar from its seat. Insert the new 20 mm strap by threading the barrels through the lug rings, ensuring perfect seating before repositioning the spring bars into their original positions.
Can I use an aftermarket 20 mm strap on this model?
Yes, any 20 mm strap is mechanically compatible with the Heritage 113780. However, we recommend selecting a strap of artisanal quality that respects the watch's material density and proportions. A strap with a metal <a href="/pages/termine-glossario/deployante">deployant</a> clasp in noble metals (gold or steel) maintains constructive coherence with the original timepiece.
How long does a leather strap last on a watch like the Montblanc Heritage 113780?
A quality leather strap with traditional tanning has a lifespan of 3–5 years under moderate daily wear. Factors including perspiration exposure, humidity, and cleaning frequency influence durability. To extend strap longevity, avoid water immersion and periodically apply specialised conditioner. The developing patina is integral to the aesthetic and represents noble ageing rather than degradation.
