Strap for PrimaLuna Automatic 30 Pink Gold Leather Arabic

The Longines PrimaLuna L8.113.8.16.2 features a lug width of 8mm. This dimension is specific to this model and requires custom-built straps. Measurement should be taken between the two attachment points on the case, not the overall case diameter (which is 30mm). An 8mm strap must fit into the lugs with slight resistance but without excessive play.

For the rose gold PrimaLuna, four options are recommended: 1) Alligator in cognac tone, maintaining the precious perception of gold without competing with it; 2) Smooth black calf, for formal contrast and classical elegance; 3) Vegetable-tanned calf in light grey, for daily wear with natural patina development; 4) Bordeaux shell cordovan, for those desiring visible mirror-like ageing over time. Alligator represents the reference choice for evening occasions.

The procedure is identical to any watch: use a spring bar tool to gently lift the bent ends of the spring bars and slide the old strap out of the case. Position the new strap aligning both sides to the lugs, applying slight pressure until engagement. Verify the strap is secure by moving the case laterally—it should present no oscillation. With rose gold watches, we recommend performing the operation with care to avoid micro-scratches on the case.

Yes, quality aftermarket straps built for 8mm lugs are available. Milano Straps offers a selection of 8mm straps in ready-to-ship leather (alligator, calf, shell cordovan) customisable in length, initials, and stitching thread. The Casati Milano atelier also creates fully bespoke straps with personal leather selection and 18-month warranty, operating by appointment for a complete bespoke experience.

Leather strap longevity depends on use intensity and material. Quality smooth calf resists 2-3 years of daily use before replacement becomes necessary for aesthetic reasons. Alligator and shell cordovan, being more robust leathers, can extend to 4-5 years. Factors reducing durability include prolonged moisture exposure, acidic perspiration, direct sunlight, and repeated flexing. Vegetable tanning develops visible patina but requires conscious maintenance with specific oils to maintain elasticity.
