Strap for Evidenza 33.1 Automatic Pink Gold

The lug width of the Longines Evidenza L2.642.8.73.6 is 18.00mm. This measurement is specific to Longines women's models from the 1990s and represents an intermediate size not covered by standard mass-production strap manufacturers. To verify compatibility, measure the distance between the lugs from outer edge to outer edge: it must be exactly 18mm.

For the Longines Evidenza L2.642.8.73.6 in 18kt rose gold, noble materials such as alligator and shell cordovan represent the most appropriate choices. Dark brown or mahogany alligator creates a natural chromatic harmony with the gold case, while reddish shell cordovan develops personalised patina over time. Vegetable-tanned calf leather offers initial comfort and natural ageing. NATO and rubber straps are discouraged to maintain the aesthetic coherence of the timepiece.

Strap replacement requires the use of a spring bar tool (Y-shaped screwdriver or dedicated lever). Insert the tip of the tool into the small lateral holes in the case, gently compress the internal spring of the lug (spring bar) and slide the strap out. Reverse the procedure to install the new strap. Work on a flat, protected surface. For those who prefer to avoid DIY, professionals at Casati Milano handle strap changes with artisanal methodology.

Yes, it is possible to use compatible aftermarket straps provided the lug width is exactly 18.00mm. The selection of aftermarket straps in this size is more limited compared to standard formats (16mm, 20mm, 22mm), but specialist manufacturers such as Milano Straps offer options in alligator, shell cordovan and calf leather, customisable in length, initials and thread colour. It is important to verify exact dimensions before purchase.

The lifespan of a leather strap depends on material, usage and maintenance. Quality alligator with vegetable tanning can last 5-7 years with moderate daily wear; shell cordovan, owing to its density, can exceed 10 years. Vegetable-tanned calf has lifespan similar to alligator, approximately 5-6 years. The primary wear manifests in the pin hole, which requires strap extension or replacement. With proper care and rotation between multiple straps, longevity increases significantly.
