Strap for PrimaLuna Quartz 26.5 Stainless Steel / Yellow Gold / White

The Longines PrimaLuna L8.110.5.90.2 features a lug width of 6mm. This specific dimension is determined by the spring bar posts that protrude from the case; a compatible strap must measure exactly 6mm between the two attachment points to ensure secure anchorage without mechanical play. It is essential to verify this measurement before purchasing an aftermarket strap.

Given the delicate proportions of the case (26.50mm), alligator straps with vegetable tanning represent the most harmonious choice: the fine scales and patina that develops over time mirror the discreet elegance of the model. Alternatively, vegetable-tanned calf leather offers a smooth, formal surface, whilst a vulcanised rubber strap provides technical versatility without aesthetic compromise.

Strap replacement is accomplished by removing the spring bars that connect the lugs to the case. Using a dedicated tool (spring bar removal tool), the bars are lifted by gently pushing them towards the case body until they disengage. Once the old strap is removed, the new strap is aligned with the bar holes and the bars are reinserted into the case lugs. The operation requires precision to avoid scratching the case.

Yes, provided that the strap is constructed with a lug width of exactly 6mm and the spring bars are compatible with the case lugs. Many bespoke strap manufacturers produce custom straps for this specific measurement. It is advisable to verify precise dimensions before purchase and, if possible, conduct a fit test to ensure the strap is neither too loose nor too tight.

The lifespan of a leather strap depends on usage intensity and tanning quality. A strap crafted from quality leather (alligator or Italian vegetable-tanned calf) may last 3-7 years of regular use; if worn occasionally, longevity extends significantly. Wear manifests primarily at the flex point inside the lug. Vulcanised rubber straps offer greater durability in humid environments, exceeding 10 years with minimal maintenance.
