Strap for Conquest Classic Automatic 40 Stainless Steel / Red Gold / Black

The lug width of the Longines Conquest Classic L2.785.5.56.7 is 20 mm. This dimension represents the distance between the case lugs where the strap attaches, and must not be confused with the case diameter (40 mm). A 20 mm strap is essential to ensure a secure fit and correct aesthetic presentation on the wrist.

The best strap depends on usage and personal preference. Dark brown alligator is the reference choice for daily elegance, as it develops natural patina and resists moisture. For those seeking sport versatility, burgundy shell cordovan creates chromatic harmony with rose gold but requires regular maintenance. Tuscan vintage calf is excellent for those desiring natural ageing without the rituals of cordovan.

To change the strap on the L2.785.5.56.7, remove the original strap by sliding the spring bars out from the case lugs. You can use a spring bar remover or a thin flat screwdriver. Insert the new strap by aligning the hole with the spring bar mechanism, pushing until it clicks. Verify the strap is firmly secured before wearing the watch. Do not force the bars: if they resist, the strap may have incorrect tolerances.

Yes, all 20 mm straps are compatible with the L2.785.5.56.7, provided the lug width is respected. Always verify that the manufacturer specifies '20 mm' as the lug width. Personalised straps from specialist ateliers guarantee superior quality to generic online products and offer measurement and alteration services without additional costs.

Durability depends on the material and usage. An alligator used daily lasts 5–7 years before showing significant aesthetic wear; shell cordovan resists 3–5 years if not exposed to humid climates and dried quickly after perspiration. Vintage calf, being softer, softens naturally in 2–3 months but ages for 6–8 years. Regular maintenance (cleaning, annual conditioning) significantly extends useful life.
