Strap for Conquest V.H.P. 41 PVD / Black / Rubber

The lug width of the Longines Conquest V.H.P. L3.716.2.56.9 is 20 millimetres. This measurement represents the distance between the two contact points of the spring bars on the case lugs and is essential for compatibility with aftermarket straps. A 20mm width falls within the established standard for mid-to-large sports watch segments and allows access to a comprehensive range of artisanal straps without requiring structural modifications.

Several options are recommended for the Longines Conquest V.H.P. depending on intended use and aesthetic preference. Vegetable-tanned alligator provides classical elegance whilst maintaining sportiness; vegetable-tanned calf offers versatility and reduced maintenance; shell cordovan ensures exceptional longevity and an inimitable patina; rubber or canvas NATO straps preserve authentic sportiness. The choice depends on the desired balance between formality and casual wear.

To change the strap on a Longines Conquest V.H.P., you must remove the spring bars connecting the strap to the case lugs. Use a dedicated strap-changing tool or a fine needle to press the spring bars inward, releasing the strap ends. Once the spring bars are removed, extract the old strap and insert the new one, ensuring the spring bars are correctly positioned in their respective cavities. This operation requires care to avoid damaging the case lugs.

Yes, the Longines Conquest V.H.P. L3.716.2.56.9 with a 20mm lug width is fully compatible with aftermarket straps of the same width. High-quality artisanal straps in alligator, calf, shell cordovan or rubber guarantee a perfect fit and allow customisation in terms of colour, texture and clasp type (standard or deployante). The universal compatibility of the 20mm measurement offers substantial freedom for seasonal rotation and personal styling.

The lifespan of a leather strap depends on the material, tanning method and intensity of use. A well-maintained vegetable-tanned calf strap has an average life of 3-5 years in daily use; properly cared-for alligator can exceed 7-8 years; shell cordovan, thanks to its molecular structure and inherent resilience, may last 10-15 years or longer. Proper maintenance—including periodic cleaning, avoiding prolonged moisture exposure and protecting against direct UV rays—significantly extends strap longevity.
