Strap for Classique Date Quartz 39mm Bracelet

The lug width of the Montblanc Star 108768 is 19 millimetres. This measurement represents the distance between the two metal lugs that extend from the case and accommodate the strap. It is the standard dimension for this model and determines compatibility with all aftermarket straps.

For the Montblanc Star 108768, straps in natural alligator or vegetable-tanned calf leather represent the most refined choices, as they enhance the model's aesthetic sobriety. Alligator develops a unique patina over time, whilst calf offers superior softness. For more casual interpretations, a NATO strap in heavyweight cotton dyed indigo or charcoal grey is an excellent solution.

Changing the strap on the 108768 requires the use of a specific tool: a spring bar removal tool or lug removal lever. Remove the original strap by gently levering the metal lugs, then position the new strap by aligning the holes with the case pins. If you do not possess these tools, it is advisable to consult a professional watchmaker.

Yes, any strap with a 19mm lug width is perfectly compatible with the Montblanc Star 108768. High-quality artisanal straps, crafted from alligator, calf, crocodile leather or technical materials such as vulcanised rubber, fit the original lugs perfectly without requiring any modifications.

The lifespan of a leather strap depends on frequency of wear, climatic conditions and type of tanning. A vegetable-tanned calf strap, worn daily, has an average lifespan of 3-5 years before requiring replacement. Alligator, thanks to superior skin density, can last 5-7 years. Humidity and prolonged sun exposure accelerate ageing.
