Strap for PrimaLuna Quartz 30 Stainless Steel / Pink Gold / Diamond / MOP - Arabic / Bracelet

The lug width of the Longines PrimaLuna L8.112.5.88.6 is 7mm. This dimension is critical for strap compatibility. Measurement is performed using a digital calliper between the two internal lugs of the case. Milano Straps offers a complete collection of 7mm straps, customisable and ready for dispatch.

For this 30mm model with mother-of-pearl dial and two-tone steel-rose gold case, cognac alligator or black calf leather offer elegance without visual competition with the dial. Burgundy shell cordovan represents the premium choice. For versatile use, natural tanned calf creates aesthetic lightness. All straps feature vegetable tanning certification and rose gold satin hardware.

Strap replacement on the PrimaLuna L8.112.5.88.6 is executed by removing the spring bars using a dedicated tool, available in watchmaking maintenance kits. Position the watch on a soft surface to prevent scratching. Gently compress the spring bar fixing mechanism to release one end, then extract the old strap. Insert the new strap by aligning its holes with the lugs. Casati Milano offers professional strap-change service by appointment.

All straps with 7mm lug width are mechanically compatible with the L8.112.5.88.6. Milano Straps offers bespoke straps in alligator, calf, shell cordovan and NATO, customisable in length and buckle. Verify that the strap thickness at the passage hole is consistent (approximately 3.5–4mm) for optimal insertion into the case lugs.

Lifespan depends on material and daily use. An alligator or calf strap with certified vegetable tanning, worn daily, maintains functional integrity for 2–4 years before requiring maintenance or replacement. Shell cordovan, owing to its superior cellular density, can reach 5–7 years of use. The 18-month warranty offered by Casati Milano covers manufacturing defects. Patina development over time is normal and desirable in vegetable-tanned leather.
