Strap for Conquest Classic Moonphase Stainless Steel / Silver / Bracelet

The lug width of the Longines Conquest Classic L2.798.4.72.6 is 21mm. This measurement represents the internal distance between the metal lugs of the case that accommodate the strap. Measuring this dimension accurately is essential to ensure that a replacement strap fits perfectly without play or structural misalignment.

For the 42mm stainless steel Conquest Classic, we recommend genuine alligator with polished finish for a formal-sporty profile, or vegetable-tanned calf if you desire an organic patina that evolves over time. For daily use or humid climates, technical rubber or NATO fabric offers practicality and durability. The choice depends on context: executive environments favour alligator, whilst versatile wear benefits from robust materials.

Strap replacement requires specific tools: spring bar removal tools to extract the pins from the case lugs. Position the watch on a stable surface, insert the tool under the pin from the underside until gently lifting it, remove the pin and take off the old strap. Insert the new strap, aligning it with the lugs, reinsert the pin and verify secure fastening. If uncertain, entrust the task to a professional watchmaker to avoid case damage.

Yes, aftermarket straps are compatible with the Conquest Classic L2.798.4.72.6 provided they feature a 21mm lug width. Bespoke artisanal straps additionally allow selection of customisations such as material (alligator, calf, shell cordovan), colour, closure type (deployant, ardillon buckle) and thread colour. Always verify lug width before purchase.

Leather strap longevity depends on material, frequency of wear and care. A high-quality alligator or shell cordovan strap, worn occasionally, maintains structural integrity for 5-7 years. Vegetable-tanned calf develops patina more rapidly, evolving within 2-3 years; some owners favour this aesthetic evolution. Prolonged exposure to moisture, direct heat and perspiration accelerates ageing. Rotating multiple straps extends the overall lifespan of each.
