Strap for Conquest V.H.P. GMT 41 Stainless Steel / Black / Bracelet

The lug width of the Longines Conquest V.H.P. L3.718.4.56.6 is 20mm. This measurement represents the internal distance between the springbar lugs on the case. To verify correctly, use a digital calliper by positioning the callipers into the internal lateral spaces of the lugs, excluding the case edge. Accurate measurement is essential for ordering compatible straps.

The ideal material depends on use context. For formal elegance, alligator from Italian vegetable tanning represents the supreme choice: regular grain, structural robustness, and natural patina that develops over time. Italian vitello box offers aesthetic versatility and practicality. Shell cordovan guarantees rigidity and moisture resistance for sports use. NATO or rubber straps are pragmatic options for nautical contexts. The brushed stainless steel case of the Conquest harmonises with all these choices whilst maintaining formal coherence.

Changing the strap on the L3.718.4.56.6 requires only a few minutes. The case uses sprung lug attachments (springbar). Using a dedicated tool (spring bar tool) or a small flat-head screwdriver, apply gentle pressure to one side of the internal lug, lifting the springbar until it releases. Fully extract the bar from the first lug, then proceed to the second. Insert the new strap by aligning the hole with the springbar, pressing until it clicks into position. Repeat on the other side. Avoid excessive pressure that could deform the springbar.

Yes, the Longines Conquest V.H.P. L3.718.4.56.6 accepts any 20mm artisanal strap with standard sprung lug attachment. MilanoStraps offers straps in alligator, vitello, shell cordovan and technical fabrics, custom-made for wrist length, colouration, initials and stitching thread type. Using quality aftermarket straps does not affect Longines warranty, provided only suitable springbars are used and the case is not damaged during installation.

Leather strap longevity varies by material, usage and maintenance. Italian vegetable-tanned alligator resists 5–7 years under moderate daily use, developing a noble patina. Vitello box, more sensitive to moisture, offers 3–5 years on moderate wrist wear. Shell cordovan, thanks to internal varnishing, can reach 7–10 years even with frequent perspiration. MilanoStraps provides 18 months coverage on structural wear. To extend durability, avoid prolonged exposure to water and direct perspiration, apply vegetable wax every 4–6 months, and store away from direct heat sources.
