Frequently asked questions

What is the lug width of the Longines Conquest V.H.P. L3.718.2.56.9?

The lug width of the Longines Conquest V.H.P. L3.718.2.56.9 is 20mm. This is the internal distance between the two attachment pins (spring bars). This dimension makes the model compatible with standard 20mm straps, a common size among modern sports watches but distinct from the 22mm typical of divers and the 18mm of dress watches. To verify compatibility, measure the strap lug internally: it must be exactly 20mm.

What is the best strap for the Longines Conquest V.H.P. L3.718.2.56.9?

There is no single 'best' strap in absolute terms, but optimal choices depending on use. Brown or black alligator represents the most elegant and versatile choice, suitable for both formal and everyday contexts. Vegetable-tanned calf is recommended if you seek aesthetic patina over time. Japanese shell cordovan offers superior structural robustness for intensive use. NATO or synthetic rubber maintains the Conquest's sporty character with maximum practicality. The choice depends on your lifestyle and prevailing usage conditions.

How do I change the strap on my Longines Conquest V.H.P. L3.718.2.56.9?

The Longines Conquest V.H.P. L3.718.2.56.9 is fitted with standard spring bars. To change the strap: 1) Obtain a dedicated tool (spring bar remover) or a fine needle; 2) Apply gentle inward pressure on one of the lateral holes of the lug whilst carefully lifting the old strap; 3) Repeat from the opposite side; 4) Insert the new strap aligning the holes with the lugs and push until it clicks. Avoid excessive pressure which could damage the spring bar. If inexperienced, entrust the task to a professional.

Can I use an aftermarket compatible strap on my Longines Conquest V.H.P. L3.718.2.56.9?

Yes, absolutely. The Longines Conquest V.H.P. L3.718.2.56.9 uses standard 20mm spring bars, compatible with any strap of the same width. Quality aftermarket straps (artisanal or industrial) neither damage the watch nor its aesthetics; conversely, they enable infinite personalisation. The only precaution: verify that the strap has suitable thickness to pass smoothly under the lugs without excessive friction (maximum thickness 4-4.5mm). Our straps on milanostraps.it have been tested specifically on this model.

How long does a leather strap last on my Longines?

The lifespan of a leather strap depends on material, tanning method, and frequency of use. A quality alligator, with moderate use (3-4 days weekly), lasts approximately 3-5 years before requiring replacement. Vegetable-tanned calf resists 2-4 years. Shell cordovan, being denser, may exceed 5-6 years. Humidity, direct sun exposure, and perspiration accelerate ageing. Basic maintenance (drying after rain, protection from direct sunlight) significantly extends longevity. Factors such as climate, salt water, and mechanical wear are critical variables.
