Strap for PrimaLuna Quartz 34 Stainless Steel / Diamond / White / Bracelet

The lug width of the Longines PrimaLuna L8.114.0.16.6 is 9 millimetres. This is a non-standard measurement requiring specifically designed straps; straps intended for 8mm or 10mm lugs are not compatible, although manufacturing tolerances may occasionally permit adaptation. To verify the measurement, measure the distance between the two lug attachment points on the case where the original strap sits.

Dark brown or black alligator is the most natural aesthetic choice for this 34mm model: the regular texture of the reptile skin honours the slender 9mm lug width without visually overwhelming proportions. Vegetable-tanned calf offers a tactile luxury alternative with patina developing over time. For daily versatility, a FKM rubber strap maintains refined character without functional compromise.

The original strap is secured to the case via two removable lugs (a Longines construction concept). Using a lug removal tool (available at any jeweller) or a small flathead screwdriver, insert the tip into the lateral hole of the lug and apply gentle pressure to extract the pin. Once both pins are removed, the original strap releases. Position the new strap by aligning its holes with the case lugs and push the pins until they seat firmly.

Yes, any strap with a 9-millimetre lug width is compatible with the L8.114.0.16.6. Bespoke artisanal straps represent the primary aftermarket territory for this specific measurement, as industrial production rarely accommodates the 9mm lug. Always verify the declared lug width from the manufacturer and, if needed, contact the atelier directly for dimensional confirmation.

A quality alligator strap (full-grain leather, not split) with appropriate tanning resists 3–5 years of regular wear before replacement becomes necessary due to thinning at the lugs. Vegetable-tanned calf typically performs within the lower range (2–3 years) as the leather is softer and absorbs moisture more readily. Longevity depends on sun exposure, body perspiration, humidity and frequency of use. A well-maintained strap (periodically cleaned and dried after moisture exposure) easily exceeds these benchmarks.
