Strap for Conquest Heritage Stainless Steel / Silver

The lug width (misura ansa) of the Longines Conquest Heritage L1.611.4.75.2 is 20mm. This parameter is fundamental for selecting a compatible strap. The measurement is taken by calculating the distance between the two lugs without exerting pressure on the case. A 20mm strap inserts with precision, ensuring stability and protection of the case's finishing.

The best strap depends on intended use. For formal and vintage-inspired contexts, we recommend alligator with vegetable tanning in tobacco or dark burgundy shades: the regular grain enhances the classic elegance of the model. For versatile daily wear, smooth leather (box calf or aniline) offers balance between maintainability and refinement. For those who value aesthetic evolution and patina development, shell cordovan is an extraordinary choice thanks to the fibre's density and brownish undertones over time.

The process is straightforward: use a spring bar tool to gently remove the pins from the case's lugs. Insert the small hook of the tool beneath the pin, exert slight pressure to release the internal spring, then extract the pin. Repeat for the second pin. Position the pins on the new strap, align them with the lugs and insert them firmly until you feel the safety spring click. Verify that the strap is perfectly secured before wearing the watch.

Yes, absolutely. Provided the strap is 20mm and crafted from superior materials, an artisanal aftermarket strap is not only compatible but can completely transform the aesthetic character of the watch. Artisanal straps in fine leather (alligator, shell cordovan, premium calf) commonly offer superior construction quality to OEM straps from generalist brands, ensuring durability and beauty that improve over time with natural patina development.

Lifespan depends on material and usage. A standard calf leather strap, worn daily, typically lasts 18-36 months before showing visible wear. An alligator or shell cordovan strap with vegetable tanning, thanks to fibre density, can last 3-5 years under normal conditions. Non-daily wear significantly extends longevity. Regular maintenance—cleaning with a soft damp cloth, conditioning with natural waxes every 6 months—substantially extends lifespan. Remember that natural patina is desirable and valuable, not a sign of deterioration.
