Strap for PrimaLuna Quartz 26.5 Stainless Steel / Diamond / White / Bracelet

The lug width of the Longines PrimaLuna L8.110.0.16.6 is 6mm. This measurement represents the space between the two lugs (spring bar posts) where the strap attaches, and it remains fixed. To verify this measurement, remove the strap and measure the distance between the lug holes on the case: you will find exactly 6mm. Do not confuse this with the strap width itself, which can vary between 16 and 20mm depending on your aesthetic preference.

For the PrimaLuna L8.110.0.16.6, we primarily recommend alligator leather, particularly in bordeaux, cognac, or black pearl tonalities. The natural grain of alligator complements the satinised steel case perfectly and emphasises the lunar complication on the dial. Alligator also develops an evolving patina over time. As a durable alternative, satin vitello in dark brown or black maintains formal elegance. For technical and practical daily use, shell cordovan offers superior structural compactness. High-quality rubber or composite straps remain valid for those who prefer everyday practicality.

Changing the strap on the PrimaLuna L8.110.0.16.6 involves removing the spring bars. Position the watch with the lugs facing you, locate the small button beside the upper spring bar and gently press downward with the appropriate tool (spring bar tool), releasing the bar from its seat. Repeat for the lower bar. Once the bars are free, you can remove the old strap and insert the new one, ensuring the bars fit perfectly into their seats. If you are uncertain, consult a professional watchmaker to avoid damage to the case.

Yes, the PrimaLuna L8.110.0.16.6 is fully compatible with all aftermarket straps that specify 6mm lug width. The 6mm measurement is the determining criterion: any strap manufactured for this lug width will fit correctly on your case. Online you will find an extensive selection of 6mm straps in alligator, vitello, shell cordovan, and technical materials, ready for dispatch and customisable with initials and stitching thread colour. Be careful not to confuse with 5mm or 7mm straps, which will not fit.

The lifespan of a leather strap depends on usage and tanning quality. An alligator strap with artisanal vegetable tanning, worn daily, maintains structural integrity for 3-4 years before showing signs of wear on the keeper loop. Quality satin vitello has a slightly shorter lifespan of approximately 2-3 years with daily wear. Shell cordovan, thanks to its structural compactness, reaches 4-5 years. Aging is natural and desirable: the patina that develops imparts character to the strap. To extend strap life, alternate use with at least one other strap and condition the leather every 6-8 months with specialist product. Rubber straps have superior longevity, 5-7 years, with minimal maintenance.
