Strap for PrimaLuna Quartz 26.5 Stainless Steel / Pink Gold / Diamond / Silver - Roman

The Longines PrimaLuna L8.110.5.79.2 features a lug width of 6 millimetres. This measurement is critical when selecting a compatible strap: any strap designed for this model must have a 6mm lug width to fit correctly within the case lugs without lateral play or contact with the bezel.

The optimal choice depends on intended use and dial finish. Polished black alligator remains the most versatile option for formal occasions, as its minimal grain structure aligns with the case's aesthetic rigour. For classical elegance, vegetable-tanned calf leather in dark tones (deep brown or oxblood) develops a desirable patina over time. Shell cordovan is recommended for those seeking exceptional durability and pronounced texture. All materials should be paired with either a stainless steel deployant clasp or, for added luxury, an 18-karat rose gold variant.

Strap replacement requires a spring bar tool. Position the watch on a soft surface to prevent scratching. Insert the tool's tip into the lateral aperture of the lug guide and apply gentle downward pressure until the spring bar pin releases. Repeat on the opposite side. Once both pins are freed, the strap slides away. Installation proceeds in reverse: align the strap's ocelli with the lug apertures and press until the spring bars snap into place with an audible click of confirmation.

Yes. Any artisanal or industrial strap with a 6-millimetre lug width is compatible with the PrimaLuna L8.110.5.79.2, provided the shoulders (conical segments inserted into the lugs) are proportioned to the case geometry. Bespoke artisanal straps guarantee optimal aesthetic compatibility, as all parameters—shoulder profile, width, length, thickness—are calibrated to your specific timepiece.

Longevity varies by material and usage pattern. A vegetable-tanned calf strap typically endures 3–5 years of daily wear before significant degradation occurs (buckle failure, seam rupture). Alligator and shell cordovan, being denser leathers, achieve 5–7 years. Wear is natural and desirable—the patina that develops narrates your personal relationship with the watch. To extend lifespan, avoid prolonged moisture exposure and occasionally apply leather-specific conditioning oils. A specialist workshop (such as Casati Milano) can renovate the buckle or restitch compromised sections, extending the strap's useful life considerably.
