Strap for Conquest V.H.P. Chronograph 42 Stainless Steel / Silver / Rubber

The lug width of the Longines Conquest V.H.P. L3.717.4.76.9 is 20mm. This measurement is specific to this model and allows the use of a vast range of aftermarket straps. To verify the correct measurement, position a digital calliper on the spring bars from one side to the other of the case, excluding the bars themselves.

The ideal strap depends on usage and aesthetic preferences. For formal-sporty contexts, we recommend black or smoke-grey alligator with vegetable tanning, which amplifies the watch's aviatory heritage. For everyday wear, English or French calf in dark tones (black, brown, navy blue) offers softness and sophistication. For tactical vocabulary, ballistic NATO canvas or vulcanised rubber create interesting contrast. Shell cordovan with vegetable tanning represents the choice of merit for those seeking evolutive patina over time.

Strap replacement is a straightforward operation. Obtain a spring bar tool. Position the watch on a soft surface to avoid scratches. Insert the tool into the groove of the right spring bar, gently lift until the spring yields, then extract the bar outward. Repeat for the left side. Insert the new bars into the new strap, align with the watch lugs and push until they click into place. Verify that the bars are securely positioned.

Yes, the L3.717.4.76.9 accepts aftermarket straps with a 20mm lug width. Milanostraps.it offers a complete selection of straps in alligator, calf, shell cordovan, ballistic canvas and rubber, all customisable in sizes, initials and stitching thread. All straps are designed to maintain the aesthetic and functional integrity of the timepiece.

The lifespan of a leather strap depends on the type and usage. Quality alligator and calf, with vegetable tanning, maintain structural integrity for 3-5 years in moderate daily use. Shell cordovan is notably longer-lived and can reach 5-8 years before replacement is necessary. Proper maintenance—drying after humidity exposure, protection from prolonged direct light—significantly extends longevity. NATO canvas and vulcanised rubber straps offer superior durability, often exceeding 7-10 years.
