Strap for PrimaLuna Quartz 23 Pink Gold Diamond MOP

The lug width of the Longines PrimaLuna L8.109.9.87.6 is 6mm, an exceptionally rare and ultra-compact dimension in contemporary watchmaking. This specific width ensures perfect proportions with the 23mm rose gold case and requires straps specially crafted for this narrow specification. Measurement is straightforward: place a millimetre ruler against the inner face of the lug, from the attachment point to the connection tube.

The ideal strap depends on intended use and personal aesthetic sensibility. Nile alligator represents the classical choice, offering a regular grain texture and natural patina that develops gracefully with age. Vegetable-tanned calf provides vivid texture and superior breathability. Shell cordovan, when available in 6mm format, delivers crystalline rigidity and exceptional longevity. Finally, a NATO strap in silk or jacquard permits informal personalisation while maintaining the elegance of the rose gold case.

Strap replacement requires minimal tools: a spring bar tool (strap remover) and a stable work surface. Locate the small metal tube (spring bar) connecting the strap to the lugs. Insert the spring bar tool into the lateral groove of the tube, apply gentle pressure to compress the internal spring, and slide the strap outward. Repeat the procedure on the opposite lug. Given the rose gold quality of this timepiece, professional watchmaker assistance is recommended.

Absolutely. An artisanal aftermarket strap in alligator, calf, or shell cordovan is not only compatible but often represents the superior choice for personalising the PrimaLuna L8.109.9.87.6. It is essential to verify that the lug width is precisely 6mm and that the strap has been hand-sewn with quality thread. Artisanal straps from Milano Straps guarantee constructive precision and leather selection that frequently exceeds original equipment manufacturer offerings.

Longevity depends on leather type, construction quality, and daily usage patterns. A strap crafted in alligator or shell cordovan, with proper maintenance, can endure 8-12 years. Vegetable-tanned calf, more delicate in nature, typically resists 4-6 years of regular wear. Maintenance consists of maintaining the strap dry, avoiding prolonged direct sunlight exposure, and occasionally conditioning the leather with specialist balms. An artisanal Milano Straps strap includes an 18-month warranty against manufacturing defects.
