Strap for PrimaLuna Quartz 30 Stainless Steel / Yellow Gold / Diamond / MOP / Bracelet

The lug width of the Longines PrimaLuna L8.112.5.97.6 is 7mm. This dimension is characteristic of compact women's watches and is not standardised like more common sizes of 18mm or 20mm. It is essential to verify this measurement with a digital calliper before ordering a strap, positioning the tool perpendicularly to the lug shoulders at the strap entry point.

Alligator is the optimal choice for the PrimaLuna L8.112.5.97.6. The regular grain of alligator, in chocolate brown or black tones, creates aesthetic balance with the mother-of-pearl dial without creating visual competition. Shell cordovan and vegetable-tanned calf represent valid alternatives, respectively for those seeking a patina that ennobles with age and those preferring a softer, more everyday texture.

The strap of the PrimaLuna L8.112.5.97.6 is changed by acting on the spring bar lugs of the case. Using a specialised tool (spring bar tool), insert the tip into the hole located beneath the lug, gently pushing downward to compress the internal spring of the bar. Once the bar is freed, the strap slides away. The operation requires precision given the compact 7mm dimension: it is advisable to have it performed by a professional watchmaker to avoid scratching the case.

Yes, a quality aftermarket strap made for 7mm lug width is fully compatible with the PrimaLuna L8.112.5.97.6, provided the measurement is precise. Straps in alligator, calf, cordovan and NATO produced by specialist craftsmen maintain the same construction and durability standards as original Longines straps, often with greater customisation and choice of materials.

The lifespan of a leather strap depends on daily use, environmental conditions and quality of craftsmanship. An artisanally-made alligator or cordovan strap can last 3-5 years of intensive daily use, developing characteristic patina over time. Vegetable-tanned leathers require periodic conditioning (every 6-12 months) to remain supple and prevent cracking. The standard warranty is typically 18 months from purchase from specialist craftsmen.
