Strap for Evidenza 26 Quartz Diamond

The lug width of the Longines Evidenza L2.155.0.57.2 is 14mm. This is a non-standard measurement, smaller than conventional 16mm or 18mm widths, proportioned to the compact 26mm case size. To verify compatibility, measure the internal space between the case lugs using a digital calliper: the linear distance must be exactly 14mm.

For the Longines Evidenza, we recommend straps in alligator with fine grain (Havana or Cognac brown) for understated elegance and extended durability. Vegetable-tanned calf leather offers an alternative for those who prefer tactile softness. Shell cordovan is an extremely rare option given the 14mm lug width. Avoid NATO and technical fabrics: they contradict the refined atmosphere of the watch.

The Longines Evidenza uses straight-bar lugs. Obtain a fine-tipped flathead screwdriver or dedicated tool. Insert the tip into the lateral retention hole on the upper lug and gently push the pin outward until it fully emerges. Repeat for the lower lug. Align the new 14mm strap's bars with the lug seats and reinsert the pins from bottom to top, verifying mechanical engagement.

Yes, artisanal 14mm straps are fully compatible. Verify that the lug width is precisely 14mm and that the bars have been manufactured to correct tolerances (i.e., internal thickness compatible with original Longines pins). Milano Straps offers a dedicated collection of 14mm straps customisable in leather, colour and finishes, guaranteed for 18 months through the Casati Milano atelier.

A quality alligator strap with vegetable tanning lasts approximately 5–8 years of daily wear, developing natural patina that enhances character. Vegetable-tanned calf leather has similar longevity but requires periodic conditioning with leather creams every 6–12 months. Shell cordovan, if procurable for this lug width, extends life to 8–12 years due to inherent strength. Ageing is not a defect but aesthetic evolution consistent with the Evidenza's classical design.
