Strap for PrimaLuna Quartz 26.5 Stainless Steel / Yellow Gold / Diamond / Silver - Roman / Bracelet

The Longines PrimaLuna L8.110.5.95.6 features a lug width of 6mm, a compact and precise measurement. This dimension requires straps specifically constructed for this geometry, with micrometric tolerance on the horizontal attachment bar (6.00mm ± 0.1mm). It is not a standard sizing available in generic catalogues, but rather a rarity that characterises Longines' small female-sized cases.

The choice depends on usage context and personal aesthetic sensibility. For pure elegance, alligator leather in vegetable tannage maintains harmonious proportions on the bimetallic case. Italian calf with natural patina offers versatility and aesthetic evolution over time. Shell Cordovan creates compelling contrast between dark tones and the case's metallic finish. For daily practicality, rubber straps with hand-stitching guarantee robustness without visual compromise.

The process is straightforward: obtain a spring bar tool designed for delicate lugs. Insert the tool tip into the lateral slot of the lug spring, press gently inward on the case and pull the strap towards you. The lug spring will retract, freeing the strap. To install the new one, align the 6mm attachment bar with the lug and push it inward until the spring clicks into position. Repeat on the opposite side. Avoid abrupt movements, especially on a delicate bimetallic case.

No. The 6mm lug width is highly specific and incompatible with standard straps of 18, 20 or 22mm. Even if you physically manage to fit them, you create dangerous mechanical play and visual instability. Always choose straps specifically engineered and certified for 6mm sizing: Milan Straps offers a dedicated 6mm collection online ready for dispatch, or you can commission a bespoke piece from the Casati Milano atelier.

Durability depends on the leather type and usage patterns. A quality alligator strap with vegetable tannage typically endures 3-4 years of daily wear before requiring surface regeneration. Shell Cordovan, being denser, extends this to 4-5 years. Italian calf, when treated with natural wax periodically, maintains structural integrity for 3 years. Quality rubber straps exceed 5 years. Casati Milano's standard guarantee is 18 months, but proper maintenance—avoiding prolonged exposure to extreme humidity and heat—significantly extends useful life.
