Strap for Presence 25.5 Automatic PVD Gold / White

The lug width of the Longines Presence L4.321.2.18.2 is 13mm. This measurement is specific to the feminine versions of the Presence collection and represents the ideal proportional ratio for the 25.50mm case diameter. To verify the measurement accurately, use a digital calliper positioned perpendicularly to the lugs, measuring the internal distance between the lug shoulders.

Recommended materials include alligator (for supreme elegance with scaled texture), vegetable-tanned calf leather (for refined minimalism and patina development over time), shell cordovan (for natural structure and deep lustre), and NATO or rubber (for contemporary versatility). The choice depends on usage context and personal aesthetic preferences. Cognac alligator and black calf remain the most versatile and sophisticated options.

The strap is changed using a spring bar removal tool or a small flathead screwdriver. Insert the tool perpendicularly to the case, slightly diagonally, to lift the small pin that secures the strap. Repeat on the opposite side. Insert the pins into the new strap following the same procedure, ensuring the pins are fully pushed toward the case. This is a straightforward operation but requires care to avoid scratching the case.

Durability depends on the material and treatment. A vegetable-tanned calf strap, with daily use and regular maintenance (gentle cleaning, avoiding prolonged moisture), can last 3-5 years. Alligator, a more resilient material, often exceeds 5-6 years. Shell cordovan, due to superior construction robustness, frequently reaches 6-8 years. Quality construction and proper maintenance (keeping it dry, occasional cleaning) significantly extend the strap's lifespan.
