Frequently asked questions

What is the lug width of the Longines Saint Imier L2.766.5.79.0?

The Longines Saint Imier L2.766.5.79.0 features a lug width of 20mm. This measurement represents the distance between the two spring bars that attach the strap to the case and is essential for ensuring perfect compatibility with any aftermarket strap. On a 41mm case, 20mm provides the ideal proportion between elegance and versatility.

Which strap is most recommended for the Longines Saint Imier L2.766.5.79.0?

For the Saint Imier L2.766.5.79.0, we recommend alligator leather in dark brown or cognac tones, which enhances the rose gold case with warmth and depth. Alternatively, natural burgundy shell cordovan develops a patina over time, whilst vegetable-tanned calf leather represents the most sustainable and elegant choice. For sports contexts, nylon NATO straps or structured rubber ensure practicality and daily comfort.

How do I change the strap on my Longines Saint Imier L2.766.5.79.0?

Strap replacement is accomplished via the two lateral spring bars that connect the strap to the case. Using a spring bar tool, gently press the small metal mechanism of the pin to extract the bar, freeing the old strap from the lugs. Insert the new strap by reversing the procedure. This intervention requires no special technical skills and can be completed in minutes at home.

Can I use an aftermarket strap for my Longines Saint Imier L2.766.5.79.0?

Yes, the Saint Imier L2.766.5.79.0 is fully compatible with quality aftermarket straps. The key is to verify that the lug width is exactly 20mm. We recommend selecting straps crafted from genuine leather (alligator, calf, shell cordovan) with reliable finishing to preserve the elegance of the rose gold and stainless steel two-tone case.

How long does a leather strap last on the Longines Saint Imier L2.766.5.79.0?

The lifespan of a leather strap depends on the material and usage patterns. Quality alligator or calf leather, rotated with other straps, has an average life of 5-7 years. Shell cordovan, more durable and structured, can last 10+ years whilst developing a splendid patina. Rubber offers 3-4 years of intensive wear. Proper maintenance—drying after perspiration contact, annual conditioning—significantly extends longevity.
