Frequently asked questions

What is the lug width of the Longines Elegant L4.309.4.87.6?

The lug width is 13mm. This is the internal distance between the two attachment pins of the case. To verify, remove the original strap and use a digital calliper to measure precisely between the attachment holes. Accurate measurement is essential for ordering compatible straps.

Which strap material is recommended for the Longines Elegant L4.309.4.87.6?

The finest pairing is Louisiana alligator with fine grain or vegetable-tanned calf leather. Both materials enhance the sober elegance of the case without adding visual weight. For less formal contexts, silk NATO straps or technical rubber straps represent versatile alternatives whilst maintaining stylistic coherence.

How do I change the strap on the Longines Elegant L4.309.4.87.6?

Strap replacement is performed by removing the attachment pins using a dedicated spring bar removal tool. Position the watch on a soft surface, align the tool with the pin and apply steady outward pressure. Once the pin is extracted, the strap releases. Install the new strap by reversing the procedure, ensuring pins are fully inserted and aligned.

Can I fit an aftermarket compatible strap on the Longines L4.309.4.87.6?

Yes, any strap with a 13mm lug width is compatible. Milano Straps offers 13mm straps in various materials and finishes, crafted artisanally to Swiss specifications. Ensure the strap has the correct width and that the pins are appropriately sized for the case diameter.

How long does a leather strap last on this model?

A quality leather strap's longevity varies based on usage and maintenance. Vegetable-tanned alligator and fine calf leather maintain structural integrity for 5–7 years with ordinary care—avoiding prolonged water exposure and applying protective balms. The deployante mechanism reduces mechanical stress, shortening flexion cycles and extending overall strap lifespan.
