Strap for PrimaLuna Quartz 26.5 Pink Gold / Diamond / Silver - Roman / Bracelet

The Longines PrimaLuna L8.110.9.78.6 features a lug width of 6 millimetres. This measurement is taken from the inside of the upper lug bar to the inside of the lower lug bar, and represents a rarity within the women's segment. Precise measurement is crucial: a digital calliper positioned perpendicularly to the lugs will provide the most accurate reading.

The optimal strap depends on intended use and aesthetic preference. For a classical approach, alligator with regular grain offers aristocratic texture without visual noise. Vegetable-tanned calf with fine grain develops a refined patina over time. Shell cordovan ensures exceptional lustre and longevity. For sport contexts, moulded rubber provides sophisticated contrast against rose gold. The ideal choice remains one that dialogues proportionally with the case.

Remove the case from the current strap using a spring bar tool to gently depress the elastic pins downwards. Once both lugs are free, slide off the old strap. For installation of the new strap, align the upper lug bar with its corresponding hole and push the elastic pin into position, verifying correct placement before proceeding with the lower lug bar.

Not all aftermarket straps are compatible. The 6mm lug width immediately excludes standard aftermarket straps (typically 7mm, 8mm, 9mm). You must specifically seek straps designed for 6mm width: many manufacturers do not offer this dimension. Milano Straps maintains a curated collection of 6mm lug width models in premium materials, ensuring certified compatibility and visual proportion.

A high-quality leather strap, subjected to ordinary wear, lasts approximately 3-4 years before requiring replacement. Longevity depends on intensity of use, climate conditions (humidity accelerates degradation), and care practices. Vegetable tanning tends to outlast chrome tanning, owing to more robust fibre structure. Milano Straps and Casati Milano offer 18-month warranty on all artisanal straps.
