The Evidenza L2.155.7.71.2 (aka: L21557712), seen from the bench

The Longines Evidenza L2.155.7.71.2 is a women's dress watch launched in the 1980s featuring a distinctive tonneau case measuring 26mm in yellow gold with diamond indices. It houses the Longines L152 manual-wind caliber with jumping minutes and instant date functions, powered by precise mechanical movement. The 14mm lug width is specifically proportioned for the tonneau silhouette, providing harmonious transition between case and strap while maintaining discretion and legibility.

Frequently asked questions

What is the lug width of the Longines Evidenza L2.155.7.71.2?

The Longines Evidenza L2.155.7.71.2 features a lug width of 14mm. This dimension is specifically calibrated to the proportions of the 26mm tonneau case. To verify compatibility, measure perpendicularly the internal distance between the two anchor pins using a digital calliper.

Which strap is best suited for the Longines Evidenza L2.155.7.71.2?

Alligator in dark brown or cognac represents the optimal choice, as its natural grain amplifies the refinement of yellow gold without aesthetic competition. Alternatively, vegetable-tanned calf leather in chestnut tones allows the acquisition of natural patina over time, transforming into a unique personal signature.

How do I change the strap on the Longines Evidenza L2.155.7.71.2?

The procedure is straightforward: obtain a spring bar removal tool. Position the watch on a soft surface to prevent scratches. Gently push the bifid end of the tool against one shoulder of the pin, retracting it slightly, and slide out the used strap. Insert the new strap into the pin holes and allow the pin to return to position. Repeat on the opposite side.

Can I use a compatible aftermarket strap on the Longines Evidenza L2.155.7.71.2?

Yes, any strap with a 14mm lug width is compatible. Milano Straps offers a selection of artisanal 14mm straps in alligator, calf leather, fabric, and rubber, customisable in length, initials, and stitch colour. Always verify that the strap is manufactured for precisely 14mm lugs.

How long does a leather strap last on the Longines Evidenza L2.155.7.71.2?

Durability depends on materials and usage patterns. High-quality alligator has an average lifespan of 5-7 years with daily wear. Vegetable-tanned calf can last 3-5 years but improves over time as it acquires patina. Leather is organic: perspiration, humidity, and sunlight exposure accelerate ageing. A premium strap from Casati Milano includes an 18-month guarantee and you can request updates and maintenance via WhatsApp.
