Strap for Spirit Zulu Time 42 Blue / Strap

The lug width of the Longines Spirit L3.812.4.93.2 is 22mm. This measurement represents the horizontal distance between the two lugs (metal protrusions on the case) where the strap is attached via spring bars. Longines selected 22mm for this 42mm case model to maintain optimal proportions between case diameter and strap width.

The Longines Spirit L3.812.4.93.2 pairs particularly well with high-quality leather straps: alligator for a rigorous military aesthetic, vegetable-tanned calf leather for a natural patina that develops with use, or NATO for those who engage in frequent water sports. The 42mm brushed stainless steel case favours materials with pronounced texture and natural tones that respect the watch's instrumental character.

The Longines Spirit L3.812.4.93.2 strap is secured by spring bars that pass through the case lugs. To remove it, position the watch with the lugs facing upward and use a tool with a fine tip (a spring bar tool) to compress the spring bar and slide the old strap free. Insert the new 22mm strap in the same position, ensuring that the spring bars are correctly seated.

Yes, the Longines Spirit L3.812.4.93.2 is fully compatible with quality aftermarket straps, provided they have a 22mm lug width. Milano Straps offers a complete selection of 22mm straps customisable in artisanal leather, alligator and calf leather, with options for length, initials and stitching thread colour. Using an aftermarket strap does not affect the official movement warranty.

The lifespan of a leather strap depends on the quality of craftsmanship and conditions of use. An artisanal vegetable-tanned leather strap like those offered by Milano Straps, with regular care (periodic cleaning and storage in a dry environment), can last between 5 and 10 years. The standard warranty is 18 months, during which manufacturing defects are fully covered. The controlled ageing of leather—patina development—is a natural and desirable process, not a fault.
