Strap for Spirit Chronograph White

The lug width of the Longines Spirit L2.705.4.23.4 is 20mm. This measurement represents the distance between the two lugs of the case. To verify compatibility, measure the space between the lugs with a calliper: if it is 20mm, any strap of that width will fit perfectly without lateral play.

Dark brown alligator is the preferred choice: its fine grain complements the sandblasted black dial without visual competition. Alternatively, vegetable-tanned calf leather develops a fascinating patina over time, or grey anthracite NATO straps maintain the aviator heritage with daily practicality.

Remove the watch from your wrist and position the case face up. Obtain spring bar tools. Insert the tip into the lateral slot of the first lug, gently lift to compress the internal spring, then extract the pin. Repeat for the second lug. Align the new strap pins with the lugs and press until you hear a click.

Yes, if the lug width is exactly 20mm. Quality aftermarket straps made with certified alligator or calf leather offer the same reliability and compatibility as original Longines straps. Ensure the pins are stainless steel and that the lugs fit without forcing.

A quality leather strap (alligator or shell cordovan) typically lasts 3-5 years of daily wear, with natural patina development. Durability depends on sun exposure, humidity, and frequency of use. Vegetable-tanned leather ages more elegantly than industrial tanning. Maintenance with protective creams significantly extends strap lifespan.
