Strap for Spirit Chronograph

The lug width of the Longines Spirit L2.705.4.53.4 is 20 millimetres. This specific measurement determines compatibility with aftermarket straps. To verify, place a ruler on the inner shoulder of the lug without removing the original strap.

For the Longines Spirit, we recommend a dark brown alligator strap or black leather with vegetable tanning. These materials complement the instrumental aesthetics and pair elegantly with the stainless steel case. Rubber or NATO fabric straps are ideal for a more casual, sporty approach.

Remove the strap by extracting the spring bars. Use a spring bar tool to gently pry out the bars from one side of the case. Once one end is free, slide out the old strap and insert the new one, ensuring the spring bars are correctly positioned before closing.

All straps with a 20mm lug width are compatible. milanostraps.it offers a wide collection of handcrafted straps in this size, customisable in leather type, colour, initials, and stitching thread. Casati Milano's atelier also creates bespoke straps with direct consultation and 18-month warranty.

A quality leather strap, crafted with vegetable tanning, typically lasts 3-5 years with daily use. Longevity depends on usage intensity, climate conditions, and maintenance. Well-cared-for leather ages naturally, developing patina and character over time, which increases the watch's aesthetic value.
