Strap for Evidenza 19.6 Diamond Black

The lug width of the Longines Evidenza L2.175.0.53.5 is 10 millimetres. This specific dimension is a coherent consequence of the reduced proportions of the 19.60 millimetre tonneau case. To verify compatibility, measure the distance between the two lugs with a calliper: if you read exactly 10 millimetres, your Evidenza is ready to accommodate any strap of this category.

For the Longines Evidenza L2.175.0.53.5, an alligator leather strap represents the most natural choice from both an aesthetic and constructive perspective. The fine and uniform grain of alligator leather mirrors the formal cleanliness of the tonneau case. Alternatively, vegetable-tanned calf leather offers patina and character, developing a depth of tone absent in fresh leather over time. NATO straps in cotton silk guarantee versatility for less formal contexts whilst maintaining the watch's rigour.

The Longines Evidenza L2.175.0.53.5 uses straight lugs (pins without ridges) to anchor the strap to the case. To change the strap: 1) position the watch on a soft cloth with the case facing downward; 2) use a dedicated spring bar tool to compress the pin from the underside; 3) remove the old strap and replace it with the new one, ensuring both ends are securely fixed. If you are unsure of the procedure, consult a professional watchmaker.

All straps with a 10 millimetre lug width and appropriate thickness (generally between 2.5 and 3.5 millimetres) are compatible. On milanostraps.it you will find a selection of quality aftermarket straps available in alligator, vegetable-tanned calf, NATO and rubber, customisable in size, initials and thread colour. The Casati Milano atelier also creates bespoke straps with personal consultation and an 18-month warranty.

The durability of a leather strap depends on the quality of the material, frequency of use and environmental conditions. A premium alligator strap can last 5–7 years of daily wear; vegetable-tanned calf leather, thanks to its robustness and the patina it develops, can last 6–10 years. NATO straps in woven fabric have similar longevity (5–8 years). Exposure to moisture, heat and direct sunlight shortens the useful life. Straps from milanostraps.it and those created by Casati Milano will include precise durability information for the chosen material at the time of purchase.
