Strap for PrimaLuna Quartz 30 Stainless Steel / Pink Gold / Silver - Roman

The Longines PrimaLuna L8.112.5.78.2 features a lug width of 7mm. This non-standard measurement is characteristic of this compact women's timepiece. To verify compatibility with aftermarket straps, measure the internal distance between the two lug holes with a calliper or ruler: it must correspond exactly to 7mm. Standard straps are typically available in 6mm, 8mm, or 10mm widths, so accurate measurement is essential before purchasing.

The ideal material depends on your intended use and aesthetic preference. Alligator leather with vegetable tanning represents the most refined choice: its regular, lustrous grain amplifies the iridescent quality of the mother-of-pearl dial, creating superior visual harmony. For daily versatility, smooth calf leather in black, burgundy, or grey-taupe offers durability and elegance. A rubber FKM strap is excellent for humid environments. Shell cordovan, whilst rare in 7mm lug width, would be the ultimate option owing to its natural lustre and exceptional resistance to abrasion.

Strap replacement requires minimal tools: a strap removal lever or precision spring bar tool. Position the watch with the lug side facing upward, locate the spring bar pin retaining the current strap, and gently depress the pin downward to release the strap. Repeat on the opposite side. To install the new strap, align the lugs with the spring bar holes and reinsert the pins until they click into place. If you lack confidence, consult an authorised service centre or the Casati Milano atelier for professional installation.

Certainly, provided the straps are specifically engineered for 7mm lug width. The artisanal straps available through Milano Straps are manufactured to exacting standards and guarantee perfect compatibility. The quality of leather, precision of stitching, and grade of deployante clasp vary depending on the chosen model, but all items are verified for dimensional accuracy. We recommend verifying technical specifications and customer reviews prior to purchase.

The lifespan of a leather strap depends on tanning method, material grade, and frequency of wear. A vegetable-tanned alligator strap, if protected from intense sunlight and extreme humidity, may last 5-10 years without replacement. A smooth calf strap typically lasts 3-5 years, particularly with daily wear. Factors such as perspiration, prolonged UV exposure, and moisture accelerate deterioration. Proper maintenance—protection during rain, periodic cleaning, and conditioning with appropriate balms—significantly extends strap longevity.
