Frequently asked questions

What is the lug width of the Longines Evidenza L2.175.0.57.6?

The lug width of the Longines Evidenza L2.175.0.57.6 is 10 mm. This measurement is specific to the model and derives from the proportions of the tonneau-shaped rectangular case. The lug width is determined by measuring the distance between the lugs protruding from the case, shoulder to shoulder, without compression. A 10 mm strap maintains the visual harmony of the original design, whilst different dimensions would compromise the case's aesthetics.

Which strap material is most suitable for the Longines Evidenza?

For the Longines Evidenza L2.175.0.57.6, we recommend three primary options: alligator, which enhances the tonneau geometry with its natural and regular scale texture; shell cordovan, which develops extraordinary patina over time and creates chromatic depth; vegetable-tanned calf leather, which offers softness and homogeneous grain. For sports contexts, NATO fabric straps provide versatility. The choice depends on the desired aesthetic register: discreet elegance with alligator, modernity with rubber, tradition with calf.

How do I change the strap on the Longines Evidenza L2.175.0.57.6?

The Longines Evidenza L2.175.0.57.6 is equipped with fixed lugs that cannot be removed. To change the strap, you must consult a specialist who will extract the case pins using dedicated tools (spring bar remover). Do not attempt this yourself on a timepiece of this quality: the risk of damaging the case is substantial. The Casati Milano atelier, specialising in bespoke straps, provides comprehensive assistance for strap replacement and installation.

Can I use an aftermarket strap on this Longines model?

Yes, you can use compatible aftermarket straps provided the lug width is exactly 10 mm. A bespoke strap allows complete personalisation in terms of material, colour, stitching thread and finishing details. Milano Straps offers 10 mm ready-made straps in various options (alligator, calf, shell cordovan) and personalizable bespoke versions. Compatibility is guaranteed by the correspondence of lug width; the build quality of the aftermarket strap determines final durability and aesthetics.

How long does a leather strap last on a watch like the Longines Evidenza?

Longevity depends on leather quality, usage and maintenance. A premium alligator or shell cordovan strap lasts approximately 5-8 years with daily wear; vegetable-tanned calf lasts 3-5 years. Leather is a living material that patinas naturally. To extend longevity, avoid prolonged moisture exposure and rotate straps periodically. Milano Straps' bespoke straps carry an 18-month guarantee and are crafted with premium leathers that age beautifully, developing patina that enhances the watch's character over time.
