FAQ
What is the lug width of the Longines Elegant L4.911.4.78.6?
The lug width (ansa) of the Longines Elegant L4.911.4.78.6 measures exactly 20 millimetres. This dimension represents the internal space between the two metal lugs on the case where the strap attaches.

Which strap do you recommend for the Longines Elegant L4.911.4.78.6?
The ideal strap depends on intended use and aesthetic preference. For formal elegance, we recommend genuine alligator or smooth calf leather in dark brown. For daily wear with natural patina development, vegetable-tanned calf leather. For sporty versatility, a robust nylon NATO strap. All are available in the 20mm size compatible with this model.
How do I change the strap on my Longines Elegant L4.911.4.78.6?
Strap replacement uses a spring bar removal tool. Locate the small metal springs (spring bars) concealed beneath the current strap at the case lugs. Gently press the tool to compress the spring and the strap releases. Insert the new 20mm strap by engaging the spring into position. If you prefer professional assistance, a watchmaker will complete the change in minutes.
Can I use an aftermarket strap on my Longines Elegant L4.911.4.78.6?
Yes, any strap with a 20mm lug width is compatible. We recommend choosing specialised manufacturers that respect the formal proportions of the Elegant collection: quality materials such as vegetable-tanned leather, alligator, shell cordovan or heavy nylon guarantee both aesthetic harmony and durability.
How long does a leather strap last on the Longines Elegant L4.911.4.78.6?
The lifespan of a leather strap depends on use and care. With daily wear, vegetable-tanned leather typically lasts 3–5 years; alligator or shell cordovan 5–8 years. The decisive factor is exposure to perspiration, moisture and sunlight. Periodic maintenance (gentle cleaning, thorough drying) and rotating with other straps significantly extends useful life.
