Strap for Conquest Heritage Yellow Gold

The lug width of the Longines Conquest Heritage L1.611.6.72.4 is 20 millimetres. This dimension represents the space between the two case lugs where the strap is inserted. A 20mm strap ensures perfect compatibility and optimal fit without wobbling or misalignment.

For the Conquest Heritage L1.611.6.72.4, we recommend a dark alligator (brown or black) with vegetable tanning, or a rigid calf leather with natural patina. These materials enhance the warmth of yellow gold and maintain the heritage character of the model. If you prefer more practical options, a navy NATO or technical rubber strap offers convenience without stylistic compromise.

To change the strap, you will need a spring bar tool. Place the watch on a soft cloth, locate the metal spring bars that secure the strap to the lugs, gently push downward with the spring bar tool to release tension, then remove the strap. Insert the new 20mm strap by reversing the procedure. If you lack experience, consult a professional watchmaker.

Yes, any strap with a 20mm lug width is compatible with the Longines Conquest Heritage L1.611.6.72.4. On milanostraps.it you will find an extensive selection of artisanal 20mm straps customisable in material, colour, size and thread. Casati Milano atelier also creates fully bespoke straps for this model.

The lifespan of a leather strap depends on frequency of use, climatic conditions and the type of tanning. Quality alligator or shell cordovan, with proper care (protection from excessive humidity, natural drying), can last 3–5 years of daily use before showing significant wear. Vegetable-tanned straps age beautifully, developing patina and extending their useful life. All straps created by Casati Milano come with an 18-month warranty.
