Strap for Presence 38.5 Automatic Small Seconds

The lug width (or lug-to-lug measurement) of the Longines Presence L4.805.4.11.6 is exactly 20 mm. This measurement represents the distance between the two spring bar attachment points on the case. Accurate verification is essential before purchasing an aftermarket strap to ensure seamless compatibility.

For the Presence L4.805.4.11.6, vegetable-tanned alligator leather straps offer maximum elegance, whilst brushed calf provides office versatility and casual cotton-polyester NATO straps enable rapid changes without tools. Choice depends on context: formal environments favour structured leather, casual use benefits from NATO practicality.

Strap replacement requires a spring bar tool (inexpensive extractor available universally). Position the tool's tip in the groove beneath the lug, gently elevate to release the spring bar, extract the old strap and insert the replacement. This is a reversible procedure requiring no specialist skills and posing no risk to the case.

Yes, provided the strap is specifically designed for a 20 mm lug width. Quality aftermarket straps (vegetable-tanned leather, vulcanised rubber) are fully compatible. Always verify lug width compatibility before purchase to prevent lateral play or forced insertion complications.

A vegetable-tanned leather strap typically lasts 3–5 years under daily use, conditional upon regular maintenance (post-rain drying, natural oil treatment every 12–18 months). Artisanal-quality straps may reach 7–8 years. Shell cordovan exhibits superior resilience (up to 10 years), whilst brushed calf is vulnerable to prolonged moisture exposure.
