Strap for Evidenza 26 Quartz Diamond

The lug width of the Longines Evidenza L2.155.0.57.6 is 14mm. This measurement corresponds to the distance between the pins of the case lugs. To verify it, measure with a calliper the space between the protruding pin ends at the lugs. This is a non-standard measurement, requiring specifically crafted straps.

Black or burgundy alligator represents the most fitting choice for the Evidenza's identity: the regular texture of the scales dialogues with the tonneau geometry of the case, amplifying Art Déco elegance. Alternatively, shell cordovan in cognac brown ages with noble patina. For daily use, vegetable-tanned calf with fine grain offers softness and durability.

The strap is changed by removing the pins connecting the strap to the case lugs. Use a spring bar tool (a spring-loaded device available in watchmaker kits) to gently press from below the lug and loosen the pin. Once the ends are free, the strap detaches. Insert the new strap of the same lug width (14mm) and secure the pins in reverse. Consult a watchmaker if you prefer not to operate manually.

The lifespan of a leather strap depends on daily use and care. A high-quality alligator strap with vegetable tanning has a longevity of 5-8 years under moderate use conditions. Shell cordovan ages better and can last beyond 10 years. To extend the strap's life, avoid prolonged moisture and occasionally apply specific leather creams. Replacement is recommended when the strap begins to show structural cracks.
