Strap for PrimaLuna Quartz 23 Two Tone MOP

The Longines PrimaLuna L8.109.5.93.6 features a lug width of 6 mm. This is the distance between the inner edges of the lugs where the strap attaches to the case. The 6 mm specification is specific to this model and ensures optimal proportions for the miniaturised case.

For the PrimaLuna L8.109.5.93.6, we recommend alligator leather as the primary choice (fine, geometric texture that complements the case's refinement) or vegetable-tanned calf (which develops a natural patina over time). Modern alternatives include technical fabric or dense cotton NATO straps. Vulcanised rubber is practical for daily wear. All straps must feature a 6 mm lug width.

Use a spring bar removal tool: position it on the ends of the metal spring inside the case lug, apply gentle pressure to release the old strap, then insert the lugs of the new strap ensuring the spring clicks into position. Verify both ends are secured symmetrically.

Yes, aftermarket straps in various materials (alligator, calf, shell cordovan, NATO, rubber) with 6 mm lug width are available online. MilanoStraps.it offers a complete selection ready for dispatch, customisable in length, initials and stitch colour. Casati Milano also creates bespoke artisanal straps.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 5-8 years with regular wear, depending on frequency of use and climate conditions. Vegetable-tanned calf straps develop patina over time, visually extending their lifespan. Vulcanised rubber has similar durability but shows wear more visibly at flex points.
