Frequently asked questions

What is the lug width of the Montblanc 1858 113860?

The Montblanc 1858 113860 features 22mm lugs. This measurement, known as lug width, is the distance between the two springbars that connect the strap to the watch case. Before purchasing a compatible strap, verify that the lugs are precisely 22mm wide.

Which strap is recommended for the Montblanc 1858 113860?

For the 113860, we recommend straps in Nile alligator (fine grain or shelled finish) or calf leather with vegetable tanning. Alligator emphasises the case's bronze finishes, whilst vegetable-tanned calf develops natural patina over time, enhancing the watch's vintage character. For intensive use, NATO straps in reinforced cordura or fluorocarbon rubber are tactical options.

How do I change the strap on my Montblanc 1858 113860?

Position the watch with the strap facing upward. Using a spring bar tool (two-pronged instrument), gently press the springbar downward, releasing one end of the strap. Repeat on the other side. Insert the new strap by clicking the springbars into their corresponding seats until you hear an audible click. Verify there is no lateral play.

Can I use an aftermarket strap with my Montblanc 1858 113860?

Yes, any strap with 22mm lug width is compatible with the 113860. Choose artisanal quality: vegetable-tanned leathers age gracefully, stainless steel brushed buckles maintain the aesthetic profile, and hand-finished construction ensures no scratches on the case during installation.

How long does a leather strap last on the Montblanc 1858 113860?

Leather strap longevity depends on usage patterns. With moderate wear (5-6 wears weekly), quality calf leather lasts 2-3 years before structural failure occurs. Vegetable-tanned alligator resists 3-5 years. Frequent exposure to perspiration, water, and sunlight accelerates ageing. Rotating between multiple straps significantly extends their lifespan.
