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

The lug width of the Longines PrimaLuna L8.112.5.89.2 is 7.00mm. This measurement should be verified using a digital calliper positioned perpendicularly between the case lugs. A compatible strap must have an exact 7mm lug width to avoid lateral play and preserve the case's aesthetic integrity.

For the PrimaLuna L8.112.5.89.2, straps in dark brown alligator with vegetable tanning, burgundy shell cordovan, or smooth black calf leather are recommended. Alligator with pronounced grain respects the model's timeless elegance; shell cordovan offers formal versatility and develops patina over time; black calf guarantees reliable daily wear. The choice depends on the occasion and which leather tone best complements the rose gold and mother-of-pearl dial.

The L8.112.5.89.2 strap is replaced using a spring bar removal tool or small screwdriver. Position the watch with the strap facing upward, locate the holes in the lugs and gently push the spring bar inward using the tool. Once the spring bar is released, the lug will come free from its seat. Repeat on the opposite side. Installation of the new strap follows the reverse procedure, ensuring the spring bars are fully seated in the case's lug holes.

Yes, many aftermarket straps are compatible with the PrimaLuna L8.112.5.89.2, provided they feature a 7mm lug width. Milano Straps offers a collection of 7mm straps customisable in leather type, colour, length and stitching thread. It is essential to verify that the lug width corresponds exactly to 7.00mm. Quality aftermarket straps allow you to dramatically alter the aesthetic character of the watch whilst maintaining perfect mechanical compatibility.

Strap longevity depends on frequency of use, material type and maintenance. An alligator strap with vegetable tanning has an average lifespan of 4–6 years with daily wear; shell cordovan, being more robust, reaches 6–8 years; smooth calf, more delicate, lasts 3–5 years. Milano Straps offers an 18-month warranty on straps crafted in-house. Periodic strap replacement is not extraordinary maintenance but a natural part of a strap's lifecycle, ageing gracefully alongside the watch case itself.
