Strap for Evidenza Chronograph Calendar Black

The lug width of the Longines Evidenza L2.688.4.58.9 is 22mm. This dimension is specific to this model and determined by the geometry of the asymmetrical tonneau case. To verify strap compatibility, measure the distance between the lug holes on the inner case: it must be exactly 22mm.

For the Longines Evidenza L2.688.4.58.9, we recommend straps in vegetable-tanned alligator (medium-fine grain, brown or burgundy tones), smooth French calf (black, brown), or shell cordovan (burgundy red, dark brown). These materials enhance the elegance of the tonneau shape and the complexity of the movement. Avoid excessively stiff or thick straps, which would burden the case proportions.

The strap on the Longines Evidenza L2.688.4.58.9 is changed by removing the spring bars at the lug ends using a dedicated tool (spring bar tool) or fine-tipped pliers. After extracting the elastic pins, the old strap slides out. To install the new 22mm strap, align the strap holes with the lugs and reinsert the pins with a slight lateral movement until the safety click. If you prefer to avoid the risk of damage to the case, contact Casati Milano for professional service.

Yes, any strap with a 22mm lug width is compatible with the Longines Evidenza L2.688.4.58.9, provided the curvature and thickness are proportionate to the tonneau case. We recommend custom artisanal straps (available from milanostraps.it) that respect the stylistic proportions of the model. Ensure that the buckle (preferably deployante) is sized for this lug width.

The average lifespan of a quality leather strap (alligator, calf, shell cordovan) is 3-5 years with daily wear, varying based on climate, frequency of use, and maintenance. A vegetable-tanned leather strap from Casati Milano includes an 18-month guarantee and can be restored through stitching and buckle repair. The patina that develops over time is natural and increases the aesthetic value of the strap.
