Strap for PrimaLuna Quartz 30 Stainless Steel / Diamond / White / Bracelet

The lug width of the Longines PrimaLuna L8.112.0.16.6 is 7mm. This is a rare measurement in the horological market, proportioned to the miniaturised 30mm case. To verify strap compatibility, measure the distance between the two lugs at their widest point using a calibrated ruler. This measurement must be respected scrupulously to avoid lateral movement or oversized straps.

Alligator leather with vegetable tanning represents the most elegant solution, coherent with the model's identity. The characteristic, symmetrical grain of the scales captures light with sophistication, whilst the leather ages magnificently, developing a rich patina. Alternatively, vegetable-tanned calf offers a tactile experience and a fascinating chromatic evolution over time. For a less formal approach, a grey talpa or navy NATO fabric strap provides daily versatility whilst maintaining elegance.

Changing the strap requires a specialised tool to remove the spring bars securing the strap to the case. Place the watch on a soft surface to protect the crystal, locate the small holes at the extremities of the case where the bars enter, and use a spring bar tool or specific lever to extract them. Once removed, slide the old strap out of the lugs and insert the new one by aligning the strap holes with the case lugs. Reinsert the spring bars until they click into position. If uncertain, consult a professional watchmaker.

Yes, any strap with a 7mm lug width is compatible with the Longines PrimaLuna L8.112.0.16.6, regardless of brand. Milano Straps offers a comprehensive collection of 7mm straps in alligator leather, calf, shell cordovan and fabric. It is essential to verify the exact lug width before purchase: even a slightly oversized strap will cause undesired movement, whilst an undersized one will not attach correctly to the case.

The lifespan of a leather strap depends on leather quality, frequency of wear and environmental conditions. A high-quality alligator or calf strap, worn daily, maintains structural integrity for 3-5 years. Natural leather wears gradually: creases deepen, grain evolves, stitching deteriorates. Signs of wear do not diminish functionality but rather confer character and history. Casati Milano offers an 18-month guarantee on all bespoke straps, with the possibility of repairs and stitching replacements over the years.
