FAQ
What is the lug width of the Longines Conquest L3.377.4.96.6?
The lug width (or strap width) of the Longines Conquest L3.377.4.96.6 is 17.00mm. This measurement is specific to this model and excludes compatibility with standard straps of different diameters. To verify the measurement, use a digital calliper positioned between the inner shoulders of the lugs (the elements connecting the strap to the case).
Which strap is most suitable for the Longines Conquest L3.377.4.96.6?
The most suitable strap depends on personal use. For business and formal contexts, we recommend alligator or smooth calf leather in dark tones with vegetable tanning, which will develop natural patina over time. For a sportier approach, shell cordovan with vegetable tanning offers decade-long durability and a distinctive aesthetic signature. A cotton NATO strap is ideal for those seeking versatility and frequent style changes.
How do I change the strap on the Longines Conquest L3.377.4.96.6?
To change the strap, position the watch on a soft support. Locate the spring bars connecting the strap to the case (visible from the sides). Using a dedicated tool (spring bar tool) or a fine-tipped screwdriver, gently push the spring bar inward to release one end of the strap, then extract the bar. Repeat from the other side. Reinsert the spring bar into the new strap by following the reverse procedure.
Can I use an aftermarket strap compatible with the Longines Conquest L3.377.4.96.6?
Yes, any strap with a 17mm lug width is compatible. Artisanal aftermarket straps in leather, rubber, or textile offer superior quality and personalisation compared to OEM options, allowing you to adapt the watch to your personal style and occasion. Always verify that the strap explicitly declares compatibility with 17mm.
How long does a leather strap last on the Longines Conquest L3.377.4.96.6?
Durability depends on the material and usage. A smooth calf or alligator strap with vegetable tanning resists 2-3 years with daily wear. Shell cordovan with vegetable tanning can last 5-10 years due to superior mechanical resistance. Frequent exposure to sunlight, water, and perspiration shortens the lifecycle. Regular maintenance (cleaning, drying, and occasionally water-repellent treatment) significantly extends strap longevity.
