Strap for PrimaLuna Quartz 30 Stainless Steel / MOP / Bracelet

The Longines PrimaLuna L8.122.4.87.6 features a lug width of 7 mm. This measurement is calculated as the distance between the inner sides of the lugs and is essential for selecting a compatible strap. 7 mm lug widths are specific to elegant and miniaturized timepieces, ensuring perfect proportions with the 30 mm case diameter.

For the PrimaLuna L8.122.4.87.6, alligator leather represents the classic choice par excellence, thanks to its natural geometric grain that enhances the watch's elegance. Shell cordovan also offers unique chromatic depth and fascinating aging characteristics. Smooth calf leather is ideal for those preferring a more contemporary and durable appearance. For versatility, a NATO fabric strap allows transitions between formal and casual contexts whilst maintaining the watch's minimalist character.

To change the strap, use a dedicated spring bar tool. Insert the flat tip of the tool into one of the lateral holes beneath the upper lug, applying gentle upward pressure to release the spring. Once the first lug is free, repeat the operation on the other side. Insert the new 7 mm strap by aligning the spring bars with the lug holes and verify the spring is correctly positioned. This operation requires no particular technical skills but demands care to avoid scratching the case.

Yes, any aftermarket strap with a 7 mm lug width is compatible with the L8.122.4.87.6. Before purchasing, always verify this measurement with the retailer, as lug width is the only limiting parameter. Milano Straps offers a comprehensive collection of 7 mm straps in materials such as alligator, calf, shell cordovan and fabrics, customizable in length, initials and stitching thread. The Casati Milano atelier also creates bespoke straps tailored to your specifications with personalised consultation.

The lifespan of a leather strap depends on material quality, usage patterns and maintenance. A quality alligator or calf strap, worn daily, typically resists 3-5 years before showing visible signs of wear. Shell cordovan, thanks to its denser fibre structure, tends to last longer (5-7 years), developing a captivating patina over time. Conscious maintenance—protecting the strap from excessive humidity and direct sunlight—significantly extends its lifespan. Milano Straps guarantees 18 months on Casati Milano bespoke straps, covering manufacturing defects and stitching issues.
