Strap for PrimaLuna Automatic 26.5 Two Tone Pink

The lug width (or strap width) of the Longines PrimaLuna L8.111.5.78.6 is 6mm. This measurement represents the internal distance between the two lugs of the case and is essential for selecting a compatible strap. Do not confuse lug width with case diameter: the PrimaLuna L8.111.5.78.6 features a 26.5mm diameter but lugs measuring exactly 6mm wide, a detail that requires specifically proportioned straps.

The best strap depends on your personal style and intended use. For formal elegance, an alligator with vegetable tanning or a natural shell cordovan respects the reduced proportions and minimalist character of the PrimaLuna L8.111.5.78.6. For daily practicality, a satin-finished calf leather or a fabric NATO strap provides comfort and durability. Your choice should consider the dial colour of your specific variant and the patina development you desire over time.

Changing the strap on the Longines PrimaLuna L8.111.5.78.6 requires a spring bar tool and gentle pressure. Position the tool in the slot beneath the lug, compress the internal spring lightly, and slide the bar laterally. Repeat for the opposite lug. During this operation, avoid touching the crystal and maintain delicate, controlled movements. If you feel uncertain, the Casati Milano atelier offers a quick changeover service by appointment.

The lifespan of a leather strap depends on the tanning method and frequency of use. A vegetable-tanned calf or shell cordovan, worn regularly (5–7 days per week), typically lasts 3–5 years before showing significant wear marks. An alligator strap, thanks to the natural structure of the leather, tends to last longer, up to 6–7 years. Protection from excessive perspiration and rotating with other straps extends useful life. Milanostraps guarantees its straps for 18 months.
