Strap for PrimaLuna Automatic 30 Two Tone Pink Diamond Arabic

The lug width of the Longines PrimaLuna L8.113.5.19.6 is 8mm. This measurement corresponds to the width of the leather or rubber saddle that secures the strap between the case lugs. Accurate measurement is essential: use a digital calliper positioned on the inner shoulder of one of the two metal lugs, entirely excluding the terminal attachment protrusion. Do not confuse this measurement with dial width.

For the PrimaLuna, we recommend primarily alligator leather of medium-high quality in dark brown, burgundy or black tones. The scaled surface of alligator perfectly complements the light-play of the rose gold bezel. Alternatively, shell cordovan with vegetable tanning develops a natural patina that matures beautifully over time. For daily versatility, fine-grained calf leather in mid-brown offers durability and elegance without initial stiffness.

Strap replacement is a straightforward operation. Obtain a spring bar tool and position the watch on a soft surface to prevent scratches. Insert the tool's thin blade beneath the lug pin to lift it gently, keeping the old strap under tension. Once the pin is released, remove the old strap and position the new one by aligning its central hole with the pin. Press until you feel the safety click.

Yes, any strap with an 8mm lug width is compatible with the PrimaLuna L8.113.5.19.6. Milano Straps artisanal straps are manufactured to technical specifications that accommodate the original Longines attachment without mechanical modifications. We recommend verifying that the new strap features stainless steel pins to prevent corrosion when in contact with the case lugs.

Leather strap durability depends on material and usage frequency. Premium alligator or shell cordovan, worn daily, maintains structural integrity for 3-5 years. Vegetable-tanned calf leather ages harmoniously and can endure 2-4 years of intensive use. Leather is not eternal, but strap degradation is aesthetic transformation rather than failure. Milano Straps provides an 18-month warranty on all custom straps, guaranteeing stitching and finish durability beyond this period.
