Frequently asked questions

What is the lug width of the Montblanc Heritage 113779?

The Montblanc Heritage 113779 is fitted with a 20mm lug width. This technical specification is essential for selecting compatible straps and does not allow for variation. The lug width is defined as the vertical space between the two lugs of the case.

Which strap is most suitable for the Montblanc Heritage 113779?

For the 113779, the ideal strap depends on your intended use and personal aesthetic preferences. Alligator or vegetable-tanned calf leather represent the primary choice for those wishing to maintain classical elegance. For daily wear, a heavyweight cotton NATO or sports rubber are functionally valid alternatives. All must be 20mm in width.

How do I change the strap on my Montblanc Heritage 113779?

Strap replacement involves removing the spring bars from the lugs using a dedicated spring bar tool. After inserting the new spring bars into the strap, reinstall the assembly into the lugs, verifying correct positioning. For those unfamiliar with the procedure, a professional watchmaker can complete the operation in minutes without risk of case damage.

Can I mount a 20mm aftermarket strap on my Heritage 113779?

Yes, absolutely. An aftermarket strap of the correct width (20mm) can be mounted without any case modification. It is advisable to choose reliable manufacturers that guarantee construction quality: the strap interacts daily with the skin and must offer both durability and comfort. Milanostraps.it straps are custom-made and guaranteed.

How long does a natural leather strap last on a Montblanc Heritage 113779?

The lifespan of a natural leather strap depends on use, tanning method, and care. A quality leather with vegetable tanning, rotated with other straps and kept dry, can last 3–5 years before showing visible wear. The patina that develops is often considered a desirable characteristic. Rubber or NATO straps potentially have longer service life.
