Montblanc
Heritage 111185— lug 18mm

The Montblanc Heritage 111185 features an 18mm lug width, a classic standard proportioned to the 39mm case diameter. Always measure inside the spring bar when detached to ensure precise compatibility with your new strap.

A dark brown or cognac alligator strap provides the ideal match with 18-carat rose gold. Alternatively, vegetable-tanned calf leather creates sophisticated chromatic dialogue. For intensive daily wear, a charcoal grey NATO ensures durability whilst maintaining elegance.

Use a spring bar tool to gently remove the bars connecting the strap to the lugs. Apply inward pressure on the bar, extract from the lug hole, then insert the new strap. Avoid excessive twisting that could compromise the spring bars.

Yes, any 18mm strap is compatible. We recommend Italian artisanal leather with vegetable tanning or genuine alligator. Avoid synthetically finished straps that clash with the sophistication of rose gold.

A quality leather strap lasts 3-4 years of daily wear, extending to 5-6 years with moderate use. Longevity depends on frequency of wear, climatic conditions and regular maintenance. Leather and alligator develop patina that increases their appeal over time.
