Strap for PrimaLuna Quartz 26.5 Stainless Steel / Yellow Gold / Diamond / MOP

The lug width of the Longines PrimaLuna L8.110.5.97.2 is 6mm. This dimension is measured internally between the two lugs, wall to wall. To verify correct measurement, use a digital calliper positioned perpendicularly to the lugs. This specific measurement identifies the model within the PrimaLuna range and guarantees compatibility with quality artisanal straps.

For the opalescent mother-of-pearl dial of the L8.110.5.97.2, we recommend alligator straps in burgundy or cognac, which enhance the dial's luminous reflections. Vegetable-tanned leather in neutral tones (beige, pearl grey) offers elegant sobriety. Shell cordovan, with its naturally aging patina, transforms the watch into a personal companion over time. For summer versatility, a thin rubber strap in black maintains formality without compromise.

Changing the strap on a 6mm lug watch requires two tools: a spring bar tool (steel lever with rounded tips) and a flat surface. Position the watch face-down, insert the spring bar tool tip into the tiny hole on the lug's inner edge, apply slight pressure to release the internal spring, and extract the metal pin. Repeat on the opposite lug. Insert the new strap by threading one end of the spring first, then the other, verifying the locking click.

Yes, it is possible to use aftermarket straps compatible with 6mm lug width. Always verify that the strap specifies exactly 6mm width: even half a millimetre difference would cause excessive play or prevent fitting. Artisanal leather straps of quality (alligator, calf, shell cordovan) complement the elegance of the two-tone case. Avoid generic or low-quality straps that do not do justice to the watch's refined design.

A quality artisanal leather strap, made with vegetable tanning or alligator leather, has an average lifespan of 3-5 years with moderate daily wear. Durability depends on intensity of use, ambient humidity, and maintenance. Shell cordovan straps, thanks to the dense fibre structure, can last 7-10 years. To extend strap life, avoid prolonged exposure to chlorinated fresh water (pools), protect from direct sunlight, and occasionally apply a specific leather protectant. A well-maintained strap develops a patina that increases the watch's character over time.
