Strap for Elegant Collection 25.5 Automatic Stainless Steel / Red Gold / White

The lug width of the Longines Elegant L4.309.5.12.7 is 13 millimetres. This measurement is taken from the outer distance between the two metal lugs on the watch case where the strap attaches. To verify this measurement with precision, use a digital calliper or millimetre ruler, applying the measurement perpendicular to the lugs.

For the Longines Elegant, we recommend straps in natural alligator with vegetable tanning, available in black, dark brown, or burgundy tones, or calf leather with vegetable tanning that develops patina over time. A structured rubber strap offers contemporary versatility. Avoid glossy synthetic materials that contradict the sober aesthetic philosophy of the timepiece.

Strap replacement requires the use of a spring bar tool or dedicated instrument to remove the pins or lugs of the straps. Position the watch on a leather cushion to protect the case, gently remove the old strap by working on both lugs, then insert the new strap ensuring the pins are fully seated in the slots. If you are inexperienced, consult a qualified watchmaker.

Yes, aftermarket straps are fully compatible with the Longines Elegant provided they respect the 13-millimetre lug width. Milano Straps offers a complete collection of customisable straps for this width, crafted in natural leather and available in multiple colour and finish variants.

The lifespan of a leather strap depends on frequency of use, climatic conditions, and material quality. An alligator or calf strap with vegetable tanning, worn daily, maintains structural integrity for 3–5 years. Prolonged exposure to humidity, perspiration, and direct sunlight accelerates aging. The 18-month warranty offered by Casati Milano covers manufacturing defects and hidden vice.
