It houses the L615.2 quartz caliber certified COSC, ensuring ±10 seconds per month precision. The 20 mm lug width is essential for strap selection, measured between the inner edges of both lugs.

Frequently asked questions

What is the lug width of the Longines Presence L4.805.2.11.7?

The Longines Presence L4.805.2.11.7 features a lug width of 20 millimetres. This measurement represents the distance between the two metal pins (lugs) that attach the strap to the case. To measure correctly, use a digital calliper and measure the internal space between the lugs, ensuring your replacement strap is exactly 20 mm wide to guarantee perfect alignment with the Longines case.

Which strap material is best suited for the Longines Presence L4.805.2.11.7?

For the Longines Presence L4.805.2.11.7, we recommend three primary options. Vegetable-tanned calf leather develops a natural patina over time; French calf with fine grain maintains the model's minimalist aesthetic. Alligator offers intrinsic elegance and superior durability without requiring ageing. Shell cordovan represents the most noble investment, guaranteeing extraordinary longevity and a unique liquid patina. All these materials enhance the squared proportions and austere design philosophy of the Presence.

How do I change the strap on my Longines Presence L4.805.2.11.7?

To replace the strap, you will need a spring bar tool or should visit a professional watchmaker. Position the watch on a stable, flat surface. Insert the spring bar tool into the grooves on the side of the first lug, applying downward pressure to compress the internal spring. Remove the old strap pin, then insert the new strap pin (ensuring it is 20 mm) into the hole, pressing until you hear a final click. Repeat for the second lug. If you prefer to avoid the risk of scratching, entrust this operation to a trusted watchmaker.

Can I use an aftermarket strap on my Longines Presence L4.805.2.11.7?

Yes, provided the aftermarket strap has a lug width of 20 mm. Artisanal leather or rubber straps guarantee superior quality to generic alternatives. Milano Straps offers 20 mm straps customisable in size, colour, initials, and thread colour, all available for immediate online purchase with fast shipping. For a complete bespoke experience, Casati Milano creates custom straps with personally selected leather and WhatsApp consultation.

How long does a leather strap last on the Longines Presence L4.805.2.11.7?

The longevity of a leather strap depends on the material and frequency of wear. Quality artisanal vegetable-tanned calf typically lasts 3–5 years with daily use, developing a natural patina that enhances aesthetic value over time. Shell cordovan, being the most robust leather, can reach 7–10 years of service. Quality alligator offers a balance between durability (5–7 years) and elegance. Artisanal straps from Milano Straps and Casati Milano include an 18-month warranty, with repair services and stitch replacement available throughout the strap's life.
