Strap for PrimaLuna Quartz 34 Stainless Steel / White / Bracelet

The lug width (misura ansa) of the Longines PrimaLuna L8.114.4.16.6 is 9mm. This measurement represents the internal distance between the lateral lugs of the case and determines compatibility with aftermarket straps. It is essential to verify this measurement with precision before purchasing a replacement strap, using a digital calliper or requesting assistance from an authorised watchmaker.

For the PrimaLuna L8.114.4.16.6, alligator straps in natural or burgundy tones represent the most elegant choice, enhancing the dressy character of the timepiece. Alternatively, polished calf leather or shell cordovan treated with vegetable tanning offer daily versatility whilst maintaining formality. For those seeking a more sporty approach, rubber or textile nato straps are functional options coherent with the Swiss stainless steel construction quality of the case.

Strap replacement requires removal of the attachment lugs (spring bars) present at the ends of the lug width. Using a dedicated spring bar tool, apply gentle pressure to one of the two bars to free the original strap. Subsequently, insert the new strap by aligning its holes with the spring bars and push the bars inward until secure. It is advisable to perform this operation with a qualified watchmaker to avoid damage to the case.

Yes, it is possible to use aftermarket straps provided they are manufactured with a certified lug width of 9mm. Artisanal horological-grade straps, such as those available on milanostraps.it, are specifically engineered to guarantee precise compatibility, elevated finishing and durability over time. Choosing straps from recognised manufacturers also ensures proper deployante adjustment and better ergonomic fit to the wrist.

The lifespan of a leather strap varies according to the type of material and usage patterns. Alligator leather with vegetable tanning typically lasts 3–5 years with moderate daily wear, benefitting from the patina that develops over time. Calf leather is more resistant, with a longevity of 4–7 years. Shell cordovan reaches 8–10 years thanks to superior structural density. Regular maintenance (gentle cleaning, protection from excessive humidity and proper storage) significantly extends the useful life of any leather strap.
