Strap for Evidenza 26 Quartz Diamond

The lug width of the Longines Evidenza L2.155.0.71.6 is 14mm. This measurement is specific to the watch's asymmetrical tonneau case shape and must be measured precisely from the inner hole on one side to the inner hole on the other. The lug depth is approximately 5-6mm, a characteristic that influences the choice of compatible straps.

The best strap depends on usage and aesthetic preferences. For formal elegance, we recommend alligator or calf leather with vegetable tanning. Alligator offers a regular grain pattern that amplifies the Art Deco elegance of the case, whilst soft calf creates a comfortable second skin. A cognac-coloured strap with a steel deployante creates a particularly effective warm contrast with the satin-brushed stainless steel case.

Strap changes are straightforward and require no specialised tools. Use a spring bar tool or small toothpick to lever the internal lugs, compressing the small pin that holds them in place. Extract it completely, remove the old strap and insert the new one into the same seats. Ensure the lugs are correctly aligned before the pin clicks into place.

Yes, any strap with a 14mm lug width is compatible with the Longines Evidenza L2.155.0.71.6. Quality aftermarket straps offer an excellent solution for having multiple colour and material options without compromising durability. We recommend specialised brands that guarantee precision in lug measurement and finishing attention. The lug depth (5-6mm) excludes excessively thick straps.

The lifespan of a leather strap depends on usage, material and care. A quality calf strap typically lasts 2-3 years with moderate daily use. Alligator and shell cordovan last longer, up to 4-5 years, thanks to denser fibre structure. Vegetable tanning ages elegantly, developing patina over time. To extend strap life, avoid prolonged exposure to moisture and direct sunlight, and store in a dry environment. Straps crafted by Casati Milano come with an 18-month guarantee.
