Montblanc
Star 110589— lug 19mm

The Montblanc Star 110589 features 19.00mm lug width. This non-standardised dimension requires bespoke leather straps specifically engineered to ensure perfect fit on the wrist without lateral play or constriction.

We prioritise alligator leather, which enhances dial legibility through natural grain texture and develops elegant patina over time. Vegetable-tanned calf represents a refined alternative, whilst high-density cotton NATO straps offer a versatile sport-elegant solution.

Strap replacement is executed via springbar mechanisms integrated into the 19mm lugs. Use a dedicated springbar tool to gently depress the elastic pin, extracting the worn strap from its barrel. Insert the new strap until audible click confirms secure engagement. If the strap features a deployante, ensure the clasp mechanism aligns perfectly with your wrist.

Absolutely. Bespoke leather straps dimensioned for 19mm lugs guarantee structural and aesthetic compatibility with the 110589. Artisanal aftermarket straps in alligator, shell cordovan, or vegetable-calf often exceed industrial production quality standards, enabling complete customisation of your timepiece.

Longevity depends on usage intensity and material selection. A quality artisanal alligator strap typically lasts 4–6 years with daily wear, developing patina progressively. Vegetable-calf offers similar durability but requires careful maintenance in humid environments. Fluoroelastomer rubber straps extend to 5–8 years, whilst high-density cotton NATO straps routinely exceed five years without significant deterioration.
