Montblanc
Star 105895— lug 19mm

The Montblanc Star 105895 is fitted with 19 mm lugs (lug width). This is a specific measurement that requires a strap manufactured to this exact standard. To verify compatibility, measure the internal distance between the two lugs: it must correspond to 19 mm ± 0.2 mm tolerance.

The ideal strap depends on usage and aesthetic preference. For a classical approach, we recommend vegetable-tanned calf leather or alligator in black or brown—both develop patina over time. For greater versatility, a heavy cotton NATO or an FKM rubber strap ensures practicality whilst maintaining stylistic coherence.

The change requires a specialized tool (spring bar tool). Insert the tip gently into the slot of the lug spring, lift to extract the metal bar, then repeat on the opposite lug. Verify that the new lugs are the correct width (19 mm) before installing them. Alternatively, entrust the operation to a specialized watchmaker.

Yes, provided the lug width is exactly 19 mm. Many specialist strap makers produce custom straps for this standard. We recommend ordering from suppliers that certify technical compatibility and construction quality, avoiding generic or poorly finished materials.

A quality leather strap (vegetable-tanned, alligator, cordovan) lasts an average of 3–5 years with daily wear, developing patina and character. Lifespan depends on ambient humidity, UV exposure, and maintenance practices. Periodic conditioning with specific creams extends durability. Rubber or NATO straps last significantly longer (10+ years).
