Frequently asked questions
What is the lug width of the Longines Conquest L3.320.5.72.6?
The lug width of the Longines Conquest L3.320.5.72.6 is 15mm. This dimension is specific to small-cased Conquest models and is calibrated to maintain correct proportions between the 30mm case and strap. To measure accurately, check the distance between the two case lugs expressed in millimetres.
Which strap is best suited for the Longines Conquest L3.320.5.72.6?
The ideal strap depends on your personal style. For a formal and elegant appearance, we recommend matte anthracite alligator or smooth cognac calf leather. For those preferring a more contemporary approach, vegetable-tanned leather in natural hide colour creates a sophisticated effect and develops patina over time. For more sporting uses, a blue-and-white striped NATO maintains the prestige of the Longines movement.
How do I change the strap on the Longines Conquest L3.320.5.72.6?
The change is made through the spring bars (small metal pins) at the ends of the case. Using a spring bar tool or a thin flat instrument, apply slight pressure to compress the pin, extract the worn strap and insert the new one. Ensure the spring bars are firmly seated before wearing the watch.
Can I use an aftermarket strap on this Longines model?
Yes, it is possible to use aftermarket straps compatible with 15mm lug width, provided they are constructed with materials of equivalent or superior quality. We recommend leathers with vegetable tanning or alligator, along with finishes in rose gold or stainless steel to maintain aesthetic coherence with the bicolour case of the L3.320.5.72.6.
How long does a leather strap last on a Longines?
A quality leather strap, subject to daily wear with proper care, typically lasts 3-5 years. Factors influencing durability include: UV exposure, humidity, tanning quality, frequency of use and maintenance. Vegetable-tanned leather ages better, developing patina. We recommend replacement when wear signs (stretching, cracks) become evident.
