Strap for PrimaLuna Automatic 30 Two Tone Pink Diamond MOP

The lug width of the Longines PrimaLuna L8.113.5.89.6 is 8mm. This is a rare and technically challenging dimension requiring precision engineering in aftermarket straps. To verify the measurement, place a calliper or flexible ruler inside the lugs, from one end to the other, without applying pressure.

The choice depends on personal style. Alligator leather represents the pinnacle of refinement, with uniform scales that enhance the rose gold and steel case. Calf leather offers a classic solution that develops noble patina over time. Structured rubber straps are ideal for daily, versatile wear. We recommend choosing based on your wardrobe, intended use, and wrist proportions.

Strap replacement requires a specific tool called a spring bar tool. Position the tool's blade into the small hole on the lug, apply gentle pressure to compress the spring inside the pin, then extract the pin. Repeat on the opposite side. Insert the new strap, aligning the holes with the pins, then push until you hear the click.

Yes, you can use high-quality artisanal aftermarket straps, provided they strictly respect the 8mm lug width. Straps produced by Casati Milano and available on milanostraps.it are specifically manufactured for this size, guaranteeing perfect compatibility and durability. Each customisable strap allows you to choose leathers, colours, thread weight, and precise measurements.

The lifespan of a leather strap depends on leather quality, frequency of use, and exposure to light and moisture. A high-quality artisanal alligator or calf strap, with regular maintenance (avoid prolonged water exposure, protect from direct sunlight), can last 5-8 years. Casati Milano straps include an 18-month warranty and post-sales support to extend longevity.
