Strap for Presence 25.5 Automatic Stainless Steel / Silver

The lug width of the Longines Presence L4.321.4.78.2 is 13mm. This measurement represents the distance between the lugs that connect the case to the strap and is essential for selecting a compatible strap. Any strap with a lug width different from 13mm will not fit correctly on this model.

For the Longines Presence L4.321.4.78.2, we recommend alligator leather in vegetable tanning as the primary choice: the natural texture and the evolution of patina over time create a perfect aesthetic dialogue with the case's refinement. Alternatively, smooth calf leather accentuates the minimalist dial lines, whilst a heavy cotton canvas NATO offers daily versatility whilst maintaining elegance.

To change the strap, you must remove the spring bars using a dedicated tool (spring bar tool or strap removal tool). Position the watch on a soft cloth, then apply steady pressure outward to extract the bar. Align the new strap holes with the lugs and reinsert the bar from the opposite side. We recommend having this service performed by an expert to avoid damage.

Yes, a quality aftermarket strap is fully compatible provided the lug width is precisely 13mm. Artisanal straps crafted to the correct technical specifications do not compromise watch functionality and allow complete aesthetic personalisation, particularly through material, colour and finishing options.

A quality leather strap, crafted with vegetable tanning as with artisanal options, has an average lifespan of 3–5 years with moderate daily use. Longevity depends on the specific material (alligator lasts longer than calf), climate, humidity and frequency of use. Regular maintenance and periodic strap rest significantly extend its useful life.
