Strap for Presence 38.5 Quartz PVD Gold / White / Bracelet

The lug width of the Longines Presence L4.790.2.12.7 is 20 millimetres. This precise measurement is essential for purchasing a compatible aftermarket strap: a wider or narrower lug width would create unwanted gaps or mechanical instability. To verify the correct measurement, use a digital calliper positioned perpendicularly across the watch case lugs.

For the Presence L4.790.2.12.7, alligator leather with vegetable tanning is the reference choice: its natural grain with small, uniform cells amplifies the classical elegance of the 38.50mm case. If a more pronounced texture is preferred, shell cordovan offers superior structural density. Quality calf is a reliable alternative for those seeking chromatic versatility, whilst a cotton NATO strap is ideal for sporty interpretations without losing refinement.

The strap of the Longines Presence L4.790.2.12.7 is secured to the lugs via spring bars integrated into the case. For removal, a dedicated spring bar tool is required to gently compress the bar and extract it from its seat. Installation of the new strap follows the reverse process: insert the bar into the lugs of the new strap, ensuring it is fully locked. We recommend enlisting professional assistance to avoid damage to the lugs.

The lifespan of a leather strap for the Presence L4.790.2.12.7 depends on construction quality, tanning method, frequency of use and environmental conditions. A vegetable-tanned alligator or shell cordovan, used regularly but not daily, guarantees a lifespan of 4–7 years before replacement is necessary. Quality calf offers 3–5 years of service. Exposure to extreme humidity, direct heat or prolonged mechanical stress reduces this estimate. Proper maintenance (periodic conditioning) significantly extends longevity.
