Strap for PrimaLuna Quartz 34 Stainless Steel / Silver - Roman / Bracelet

The Longines PrimaLuna L8.114.4.71.6 features a lug width of 9mm. This measurement refers to the interior spacing between the two lateral lugs of the case. Accurate measurement of the lug width is essential before purchasing an aftermarket strap, ensuring proper fit without lateral play or structural incompatibility.

Alligator and premium calf leather represent the optimal choices for the PrimaLuna, as they emphasise the model's elegant and refined character. Genuine alligator offers naturally striated texture and rich colours; calf leather provides a supple appearance and visible patina development over time. For a more casual approach, cotton NATO straps in neutral tones transform the model with sporting personality.

Strap replacement requires a spring bar tool—a specialised instrument with two tips—to compress the internal spring mechanism of the spring bars, small pins securing the strap to the lugs. Position the PrimaLuna on a soft surface, insert the tool's tips into the lateral spring bar holes and compress gently to release the old strap. Subsequently, align the new strap to the lugs and release pressure to allow the spring bars to lock it securely.

Yes, a correctly measured 9mm aftermarket strap is entirely compatible with the Longines PrimaLuna L8.114.4.71.6. Compatibility depends exclusively on lug width; specialised brands such as Milano Straps supply 9mm straps engineered to fit the lugs perfectly without play, preserving both aesthetics and original functionality.

A premium leather strap—alligator, calf, or vegetable-tanned—typically endures 5–8 years with daily use, provided regular maintenance: avoiding prolonged moisture, preventing water immersion, and periodic cleaning with soft cloth. With occasional use, lifespan extends easily beyond ten years. Patinated leather straps improve aesthetically over time, developing character that reflects wear history.
