FAQ

What is the lug width of the Longines Elegant L4.312.4.11.6?

The lug width of the Longines Elegant L4.312.4.11.6 is 20 mm. This dimension is proportioned to the compact 34.50 mm case diameter and is the standard for female and unisex models in the Elegant collection. Always verify the lug width before purchasing an aftermarket strap by using a digital calliper or consulting an expert.

Which strap best matches the Longines Elegant L4.312.4.11.6?

For the Longines Elegant L4.312.4.11.6, we recommend smooth vegetable-tanned leather straps for a minimalist aesthetic, or alligator for those seeking texture and visual movement. If you prefer versatility, cotton or padded NATO straps are ideal for daily wear. The material should reflect the restrained character of the case: avoid eccentric patterns that would conflict with the contained proportions of the dial.

How do I change the strap on a Longines Elegant L4.312.4.11.6?

To change the strap, use a spring bar removal tool. Position the watch on a flat surface and locate the metal lugs at the sides of the case. With the small hook of the tool, gently compress the internal spring of the lug to remove it from the case hole. Repeat on the other side. Insert the new bars into the new strap and, using the same motion, secure them into the case lugs until you hear or feel a click. Never force the process.

Can I use an aftermarket strap on the Longines Elegant L4.312.4.11.6?

Yes, provided it respects the 20 mm lug width. High-quality aftermarket leather straps often offer more sophisticated finishes and materials than the original strap. Choose specialised suppliers who care about the quality of the tanning (vegetable or chrome) and stitching. On milanostraps.it you will find 20 mm straps in various materials, customisable in colour, initials and thread type, with certified warranty.

How long does a leather strap last on a watch like the Longines Elegant L4.312.4.11.6?

A quality leather strap, if properly cared for, lasts between 2 and 5 years depending on use and tanning method. Vegetable-tanned leather ages more visibly but remains durable; chrome-tanned is more consistent over time. To extend its life, avoid prolonged water exposure, occasionally apply a natural leather conditioner, and rotate use between multiple straps if the watch is worn daily. Casati Milano atelier offers an 18-month warranty on all bespoke straps.
