The model requires a specific 10mm lug width strap for proper compatibility with its unconventional case geometry.

Frequently asked questions

What is the lug width of the Longines Evidenza L2.175.4.71.6?

The lug width of the Longines Evidenza L2.175.4.71.6 is 10 millimetres. This unusual specification is determined by the asymmetrical tonneau case geometry and requires straps specifically manufactured for this aperture. Standard straps cannot be fitted without professional modification.

What is the best strap material for the Evidenza L2.175.4.71.6?

For the Longines Evidenza, we recommend vegetable-tanned alligator, which emphasises the modern geometry of the case through its characteristic grain. Neutral-tone calf leather (black, brown) offers conservative elegance, whilst rubber or NATO straps impart a contemporary sporting spirit. Material selection depends upon usage context and personal preference.

How do I change the strap on my Longines Evidenza L2.175.4.71.6?

The procedure requires a spring bar tool. Locate the two lateral case lugs, insert the tool beneath the spring bar to compress it, remove the old strap, and insert the new one by aligning the holes with the lugs. We recommend consulting a watchmaker to prevent case scratching.

Can I fit an aftermarket compatible strap to my Evidenza L2.175.4.71.6?

Yes, any strap constructed with a 10-millimetre lug width is compatible. Milano Straps provides a selection of straps in alligator, calf, rubber and textile specifically manufactured for this specification. All straps are customisable in length, colour, initials and stitching thread.

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

A quality leather strap, such as alligator or vegetable-tanned calf, maintains optimal performance for 3–5 years of daily wear. Longevity depends upon intensity of use, climate and maintenance. Milano Straps offers an 18-month warranty on all bespoke straps and provides guidance on patina preservation.
