Strap for PrimaLuna Quartz 26.5 Stainless Steel / Pink Gold / Diamond / MOP - Arabic

The lug width of the Longines PrimaLuna L8.110.5.88.2 is 6mm. This measurement represents the internal distance between the pins that secure the strap to the case and is an exclusive feature of Longines' luxury women's models. To verify the compatibility of any aftermarket strap, it is recommended to measure precisely using a digital calliper.

For the PrimaLuna with mother-of-pearl dial, we recommend dark brown alligator (mahogany or ebony brown) for a formal aesthetic, or cognac-coloured shell cordovan for a versatile look that develops rich patina over time. Natural or beige calf leather is ideal for summer wear. FKM rubber maintains practicality and ease of cleaning without compromising elegance.

Changing the strap requires a watchmaker's toolkit with a spring bar remover (a specialised lever for the pins). Position the remover under the pin and lift gently to free it from the lug slots on the case. Once the original strap is removed, insert the new one whilst maintaining pin alignment with the lugs. To avoid damaging the case finishing, it is recommended to have the operation performed by a qualified technician.

Yes, 6mm aftermarket straps are compatible with the L8.110.5.88.2, provided that the constructive tolerances respect the standard measurement (6.00mm ±0.1mm). Milano Straps offers a selection of 6mm straps in alligator, shell cordovan and calf leather, all verified for mechanical compatibility. It is nonetheless advisable to contact the staff to confirm compatibility before purchase.

Strap lifespan depends on material, usage and maintenance. A well-cared-for alligator or shell cordovan strap typically lasts 5–7 years with daily wear, owing to the density and resilience of the leather. Regenerated calf leather has similar longevity (4–6 years) if kept dry. FKM rubber offers maximum durability (7–10 years), as it resists perspiration and moisture. To prevent leather from drying out, avoid prolonged exposure to direct sunlight and constant humidity.
