Strap for PrimaLuna Quartz 26.5 Pink Gold / Silver - Roman

The lug width of the Longines PrimaLuna L8.110.8.78.2 is 6 millimetres. This measurement is essential for selecting compatible straps: the internal distance between the lugs (the pins that pass through the case) is exactly 6mm. You can verify this by measuring with a digital calliper, positioning the tool between the two lugs of the case.

The best strap depends on your intended use and personal preferences. For formal occasions: dark brown alligator or black calf leather with natural stitching. For versatile elegance: Italian calf leather with vegetable tanning in cognac tone. For maximum durability: shell cordovan. For daily wear: French calf leather in neutral shades. All straps must have a 6mm lug width to ensure perfect compatibility with the case.

Changing the strap is straightforward and requires no specialist tools. Using a spring bar tool, gently extract the pin from the case by applying slight lateral pressure to compress the internal spring, creating space to remove the old strap. Insert the new strap (always 6mm) by aligning the holes, then reinsert the pin ensuring it locks on both sides. On rose gold timepieces, operate with extreme care to avoid scratching the case.

Yes, any strap with a 6mm lug width is compatible with the PrimaLuna L8.110.8.78.2. Compatibility is guaranteed by this technical specification: 6 millimetres. Artisan manufacturers produce custom straps for this reference, personalizable in leather (alligator, calf, cordovan), colour, length and buckle type or deployante, whilst maintaining full mechanical and aesthetic compatibility.

The lifespan of a leather strap varies depending on the material and intensity of use. Vegetable-tanned calf leather typically lasts 2-4 years with daily wear, developing a beautiful patina over time. Alligator leather, being more durable, can last 4-6 years. Shell cordovan can reach 8-10 years of service. Longevity increases if the watch is not constantly exposed to perspiration, rain or direct UV rays. Periodic maintenance (gentle cleaning and drying) significantly extends strap life.
