Strap for PrimaLuna Quartz 26.5 Stainless Steel / Silver - Roman

The Longines PrimaLuna L8.110.4.71.2 features a lug width of 6mm. This measurement indicates the internal distance between the two case attachment terminals and is critical for selecting compatible straps. Even minor variations compromise strap fitment and aesthetic coherence. To verify the width, measure the internal space between the lugs with a calliper: it must correspond precisely to 6mm.

For this model, straps in alligator leather (Mississippi or Nile), vitello box in dark tones, or vegetable-tanned leather in honey and cognac hues are recommended. Dark brown alligator emphasises the minimalist elegance of the case, whilst vitello offers versatility for daily wear. For sports contexts, rubber or technical textiles maintain correct proportions without rigidity.

Strap replacement is accomplished via the lateral spring bars of the case. Use a dedicated spring bar tool to gently compress the internal springs at the terminals, releasing the old strap. Insert the new 6mm strap, ensuring the springs lock correctly at both attachment points. If inexperienced, consult a professional: improper installation can damage the delicate lugs on this compact case.

Yes, quality aftermarket 6mm straps are fully compatible. Milano Straps' straps are engineered and crafted for women's cases like the PrimaLuna, offering material quality superior to OEM Longines straps. Always verify the width is precisely 6mm and that the attachments fit without forcing.

A quality leather strap (alligator, vitello, vegetable-tanned) maintains structural integrity for 3–5 years with daily use, depending on frequency and environmental conditions. Vegetable-tanned leather develops a patina that improves over time. Factors such as humidity, prolonged heat and perspiration can shorten lifespan. Periodic maintenance (gentle cleaning, conditioning) substantially extends longevity.
