Strap for Conquest Classic Automatic 40 Red Gold / Black

The lug width of the Longines Conquest Classic L2.785.8.56.3 is 20mm. This measurement represents the distance between the two spring bars that pass through the lug lugs and accommodate the strap. It is essential to verify that any replacement strap has exactly 20mm width to ensure precise fitting and correct wearing without play or excessive tension.

The best strap depends on use and personal preference. For formal contexts, we recommend dark cognac alligator or vegetable-tanned calf, which create harmony with the rose gold case. For elegant daily use, medium brown calf with natural patina offers aesthetic solidity. For contemporary dramatic contrast, black alligator enhances the luminosity of rose gold. The 20mm lug width ensures complete compatibility with quality artisanal straps.

To change the strap, obtain a dedicated spring bar removal tool. Position the bifurcated end of the tool on the internal spring of the bar, pushing downward until the bar is released from the lug housing. Remove the old strap, insert the new one by aligning the hole with the bar, then press the bar into both lugs until you hear a click indicating secure fastening. Repeat the operation on the other lug. If unsure, a craftsman can perform the operation without additional cost.

Yes, any strap with a 20mm lug width is compatible with the Longines Conquest Classic. The artisanal market offers straps of extraordinary quality—in alligator, vegetable-tanned calf, shell cordovan and rubber—that fit perfectly into the lugs of this model. Simply ensure the strap has exactly 20mm width and that the spring bars are correctly sized to prevent play.

The lifespan of a natural leather strap depends on material and use. A quality vegetable-tanned calf typically lasts 4-6 years with daily wear, developing a desirable patina over time. Alligator, being denser, easily reaches 7-10 years. Shell cordovan, extraordinarily resistant, exceeds 10 years. Factors such as climate, humidity, frequency of use and maintenance (occasional cleaning, non-invasive conditioning) significantly influence longevity. A strap is not a permanent component of the watch, but part of its aesthetic lifecycle.
