The Longines Evidenza L2.156.4.73.6 is a tonneau-shaped chronograph presented in 1999, featuring a 30.50 mm stainless steel case with Art Deco design. It houses the automatic Longines caliber L652.2 (based on 7750) with chronograph, small seconds at 6 o'clock, and date window. Water-resistant to 30 meters and 12.4 mm thick, this model features a 16 mm lug width and bombé sapphire crystal. The dial offers multiple color options with applied indices and leaf-shaped hands, representing 1990s luxury minimalism.

Frequently asked questions

What is the lug width of the Longines Evidenza L2.156.4.73.6?

The lug width is 16 mm, an exception in the Longines catalogue that reflects the stylistic desire to maintain elegant and refined proportions on the tonneau case. To verify the lug width, insert a digital calliper between the lugs in the strap attachment area.

What is the best material for a Longines Evidenza strap?

It depends on use and aesthetic preferences. Black or dark brown alligator emphasises cocktail elegance; vegetable-tanned leather offers evolving patina over time; silk NATO ensures versatility; FKM rubber is ideal for summer. Your choice should resonate with the dial colour of your specimen.

How do I change the strap on my Longines Evidenza L2.156.4.73.6?

Use a spring bar tool to gently remove the pins connecting the strap to the lugs. Insert the tool into the case slot, lift the pin and slide it out. The new 16mm strap inserts into the opposite seat. If inexperienced, entrust the task to a professional watchmaker or Casati Milano atelier.

Can I use an aftermarket strap from another brand on my Evidenza?

Yes, provided the lug width is exactly 16 mm. Milano Straps offers a collection of straps compatible with this width, customisable in leather, colour, initials and thread colour. Always verify compatibility before purchase to avoid misalignment.

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

Durability depends on use and care. A well-maintained alligator or leather strap lasts 3-5 years under normal conditions. Constant exposure to water or sweat shortens useful life. Milano Straps guarantees 18 months on Casati Milano bespoke straps, with possibility of repair and restoration.
