Strap for PrimaLuna Automatic 30 Yellow Gold

The lug width of the Longines PrimaLuna L8.113.6.78.6 is 8mm, a specific standard for this family of women's watches. The measurement must be taken between the inner poles of the lugs, from shoulder to shoulder of the spring bar. This miniaturised dimension requires elevated constructive precision to guarantee mechanical compatibility with quality aftermarket straps.

For yellow gold of this purity, medium brown alligator represents the ideal choice: the natural scale motif creates discrete visual contrast whilst enhancing the case, and the patina that develops over time amplifies the luminous effect of the gold. Alternatively, vegetable-tanned calf offers a minimalist finish with incomparable chromatic depth. Structured rubber remains excellent for sports-oriented wear, guaranteeing water resistance and ease of maintenance.

Strap replacement occurs via the horizontal spring bar that transverses the lugs. Position the watch on a soft support, locate the microscopic holes on the bar, use a dedicated tool (spring bar tool) to gently depress one of the elastic poles, then extract the bar. Reverse the procedure for the new strap. The 8mm lug width requires precise movements to avoid damage to the lugs: we recommend professional intervention for first-time changes.

Any strap manufactured with 8mm lug width is compatible, provided total length respects Longines standard (typically 120-130mm circumference for women's wrists). Recommended materials: alligator, calf, shell cordovan, structured rubber. Milano Straps artisanal straps offer complete personalisation: leather selection, initials, stitching thread and bespoke deployante buckle.

A quality alligator or calf strap, with moderate daily use, guarantees 3-5 years of correct aesthetic and mechanical function. Vegetable tanning develops a fascinating patina that improves over time, whilst rubber remains invariant for 5-7 years. Determining factors: workmanship quality, cleaning frequency, exposure to humidity and extreme temperatures. Milano Straps offers 18-month warranty on artisanal straps and scheduled maintenance interventions.
