Strap for Conquest Classic Moonphase Red Gold / Chocolate / Triple Crown Collection

The lug width of the Longines Conquest Classic L2.798.8.62.3 is 21 mm. This measurement refers to the internal distance between the two lugs (spring bar attachments) on the watch case and determines which strap will fit correctly. Any strap with a 21 mm width will connect perfectly to the case lugs.

For the Conquest Classic in rose gold, we recommend alligator in light brown, tobacco, or smoke grey, or dark shell cordovan. These materials complement the warmth of the pink gold and develop natural patina over time. Alligator ensures elegance without sacrificing functionality, whilst shell cordovan adds contained sportiness. Avoid rubber straps, which would be stylistically discordant with the precious metal case.

To change the strap, you must remove the two spring bars using a dedicated spring bar tool with a lever. Position the tool beneath the spring bar on the side where the spring offers less resistance, press gently upwards to retract the spring, extract the bar from the case, then insert the new strap in reverse order. If unfamiliar with this procedure, it is advisable to entrust the task to an expert at Casati Milano or a qualified watchmaker.

Yes, any strap with a 21 mm lug width is compatible with the Longines Conquest Classic L2.798.8.62.3. The artisanal straps from milanostraps.it, crafted in alligator, shell cordovan, calf leather and other materials, are specifically designed for this measurement. The construction quality and selection of premium leather make these alternative straps superior to many OEM options.

A natural leather strap treated with vegetable tanning, worn daily, typically lasts 3-5 years before requiring replacement. Longevity depends on ambient humidity, frequency of water exposure, and the leather quality itself. Alligator and shell cordovan, owing to their fibrous structure, age better than standard calf leather. Proper maintenance—drying after water exposure and occasional treatment with specialist products—significantly extends the strap's lifespan.
