Strap for PrimaLuna Quartz 30 Stainless Steel / Pink Gold / White

The lug width (also called lug distance or strap width) of the Longines PrimaLuna L8.112.5.16.2 is 7mm. This is a specific and non-standard measurement, determined by the design intention to maintain optical proportions coherent with the 30mm case diameter. This dimension falls outside industrial standards (8mm, 9mm, 10mm) and requires particular attention when sourcing aftermarket straps.

For the PrimaLuna L8.112.5.16.2, a strap in alligator with C-grain or in shell cordovan with vegetable tanning is recommended. These materials respect the sober and minimalist identity of the timepiece, lending movement to the wrist without visual noise. Ideal colours are deep black, chocolate brown, or dark blue. For daily wear, a cotton NATO strap with fine texture maintains the slim profile without compromising comfort.

Strap replacement on the L8.112.5.16.2 is accomplished through the spring bars positioned at both ends of the case. Using a dedicated tool or a thin screwdriver, remove the bar from its seat by gently levering towards the inside of the case. Once the bar is extracted, the old strap is released. To fit the new strap, position the bar on the lugs, sliding the new strap slightly until the bar is fully seated in the opposite hole. It is advisable to have the operation performed by a qualified jeweller to avoid damage to the case.

All straps with a 7mm lug width are compatible with the L8.112.5.16.2. Milano Straps offers a curated selection of artisanal straps in this measurement, made in alligator leather, shell cordovan, vegetable-tanned calf, and NATO fabrics. All are customisable in size, colour, initials, and thread colour. Compatibility depends solely on the 7mm lug width: always verify the measurement before purchase.

The lifespan of a leather strap depends on the material, frequency of wear, and care. A shell cordovan strap with vegetable tanning can last 5-8 years if worn daily, developing a patina that enhances its charm. An alligator strap has a similar lifespan, typically 4-6 years. A vegetable-tanned calf strap lasts 3-5 years. Milano Straps offers an 18-month warranty on artisanal straps, covering any manufacturing defects. To extend lifespan, rotate your straps and treat the leather with specific balms every 6 months.
