Strap for PrimaLuna Quartz 30 Stainless Steel / Diamond / Silver - Roman

The Longines PrimaLuna L8.112.0.71.2 features a lug width of 7mm, a characteristic dimension found on luxury women's watches. This size requires purpose-built straps and is incompatible with standard widths such as 16mm, 18mm, or 20mm. To measure the lug width accurately, use a digital calliper positioned perpendicular to the lugs without applying pressure.

Dark brown alligator with écru stitching represents the classical choice, harmonising with the satin silver dial. Alternatively, vegetable-tanned cognac vitello amplifies summer luminosity, whilst deep black alligator conveys elegant severity. For a sport-elegant approach, FKM rubber in pearl grey maintains delicate proportions and ensures daily practicality. Shell cordovan remains the pinnacle for those seeking long-term patina development.

Strap replacement requires a spring bar tool to compress and extract the lugs from the case. Position the watch on a soft surface to prevent scratching, insert the flat tip of the spring bar tool into the lug opening, compress gently, and slide the old strap free. Repeat on the opposite side, then align the new strap's holes with the bars and secure. For inexperienced users, consultation with a watchmaker is advisable.

The PrimaLuna L8.112.0.71.2 requires 7mm lug width straps. Milano Straps curates a selection of 7mm straps in alligator, vitello, rubber, and shell cordovan, customisable in length, personalisation, and thread colour. All models are compatible with the standard 7mm lugs of this Longines and available with rapid dispatch.

Leather strap durability depends on frequency of use, climate conditions, and tanning method. Quality vegetable-tanned alligator maintains structural integrity for 3–5 years of daily wear, developing patina that enhances character. Factors including perspiration, humidity, and UV exposure accelerate ageing. FKM rubber straps, conversely, offer superior longevity (5–8 years) with minimal aesthetic evolution. Milano Straps provides 18-month warranty on all custom straps.
