Strap for Evidenza Chronograph Calendar

The Longines Evidenza L2.688.4.78.9 features a lug width of 22 millimetres. This dimension is specific to the model and ensures the correct proportions between the bombée case and the strap. To verify aftermarket strap compatibility, measure the internal distance between the two spring bars: it must be exactly 22 mm.

For this chronograph we recommend alligator in black or brown for maximum formal elegance, or shell cordovan for those who appreciate plasticity and deep patina over time. Vegetable-tanned calf is ideal for those who wear the watch daily and desire colour versatility. A lightweight rubber is the right choice if you prefer summer comfort whilst maintaining a calibrated sporty appearance.

The Longines Evidenza uses spring bars for strap attachment. With a dedicated spring bar tool you will gently remove the spring, extract the worn strap and insert a new one in the same position. It is important not to apply excessive force to avoid scratching the case. If you are not experienced, contact a trusted watchmaker.

Yes, all straps from the 22mm collection at milanostraps.it are compatible with your Longines Evidenza L2.688.4.78.9. You can personalise them in length, initials and stitching colour. For a completely bespoke experience, the Casati Milano atelier creates custom straps with direct leather selection and an 18-month warranty.

A quality natural leather strap (alligator, shell cordovan, vegetable-tanned calf) worn regularly on a chronograph like the Longines Evidenza lasts an average of 3-5 years before requiring replacement. Durability depends on frequency of wear, humidity exposure and type of tanning. Vegetable-tanned leather in particular develops a beautiful patina as it ages, making the strap increasingly attractive over time.
