Strap for Evidenza 19.6 Diamond Diamond Arabic

The lug width of the Longines Evidenza L2.175.0.57.2 is 10 mm. This is a narrow, model-specific strap width determined by the proportion between the 19.60 mm case diameter and the lug dimensions. To verify this measurement with precision, measure the internal distance between the two lugs using a digital calliper or millimetre ruler applied perpendicular to the case.

For the Longines Evidenza L2.175.0.57.2, the ideal strap depends on intended use and aesthetic preference. Alligator in vegetable-tanned leather, in dark brown or black, represents the most elegant choice, with an irregular grain pattern that dialogues with the asymmetrical tonneau case. Vintage calf in vegetable tanning is a refined alternative that develops patina over time. NATO-style straps with structured weave (anthracite grey, navy blue) suit more casual contexts, whilst vulcanised rubber offers comfort for sporting wear whilst maintaining aesthetic coherence.

The strap on the Longines Evidenza L2.175.0.57.2 is changed using a spring bar tool to extract the elastic pins (spring bars) that connect the strap to the case lugs. Position the watch on a soft cloth with the dial facing downward. Gently insert the small flathead end of the spring bar tool into the groove of the pin, extracting it completely. Repeat on the opposite side. Then insert the new strap by aligning the holes at its ends with the lugs and compress the spring bars until properly seated. If unfamiliar with this procedure, entrust the change to an authorised service centre or the Casati Milano atelier.

All straps with a 10 mm lug width are compatible with the Longines Evidenza L2.175.0.57.2. At milanostraps.it you will find a complete selection of straps in alligator, calf, NATO fabric and rubber, all handcrafted and customisable in length, initials and thread colour. Always verify that the width of the strap's terminal section (the part that inserts into the lugs) matches 10 mm to ensure a perfect fit.

The lifespan of a leather strap depends on material, usage and maintenance. A quality alligator or calf strap in vegetable tanning, worn regularly, has an average lifespan of 3–5 years. Vegetable-tanned leather typically develops a natural patina over time, increasing in beauty with age but gradually reducing initial rigidity. Patent leather straps have a slightly shorter lifespan (2–3 years). To maximise longevity: avoid prolonged direct sunlight exposure, protect from stagnant water and excessive perspiration, alternate between two straps. The Casati Milano atelier provides an 18-month warranty on all bespoke straps.
