Strap for PrimaLuna Quartz 30 Stainless Steel / Blue / Bracelet

The lug width of the PrimaLuna L8.122.4.90.6 is 8mm, a specific and relatively uncommon dimension in contemporary watchmaking. This measurement represents the distance between the internal spring bars that support the strap. Such a compact lug width requires equally precise straps to ensure a harmonious visual transition between the case and the wrist.

Genuine alligator leather remains the most appropriate choice for the PrimaLuna, thanks to its regular grain that enhances the case's classical aesthetics. Alternatively, vegetable-tanned calf leather ages beautifully and offers chromatic warmth. For daily wear, a silk NATO or structured rubber guarantee practicality without visual compromise. The ideal thickness is 1.2-1.4mm to avoid overwhelming the timepiece's delicate proportions.

Strap replacement on the PrimaLuna occurs via spring bars positioned at the lug ends. Using a dedicated removal tool allows you to depress the spring and slide the bar inward, freeing the old strap. The new strap must accommodate the same spring bars at its extremities. Given the compact 8mm lug width, operate with moderate pressure to avoid damaging the case. Alternatively, the Casati Milano atelier performs this service with watchmaking precision.

Yes, several aftermarket straps certified for the 8mm lug width exist, available in diverse materials and finishes. Milano Straps offers a dedicated collection for 8mm straps, featuring options ranging from alligator to calf, NATO to technical rubber. To ensure maximum compatibility and construction quality, always choose specialised suppliers who understand the proportional specifics of delicate watches like the PrimaLuna.

The lifespan of a leather strap depends on usage intensity and tanning quality. A high-quality alligator or calf strap, subjected to moderate wear and proper maintenance, has a useful life of 4-6 years before requiring replacement. Exposure to sunlight, perspiration, and weather accelerates ageing. The natural patina that develops over time is part of leather's beauty, but when deterioration compromises structural integrity, a new strap becomes necessary. Casati Milano offers an 18-month warranty on all made-to-measure straps.
