Frequently asked questions
What is the lug width of the Longines PrimaLuna L8.111.6.87.2?
The lug width of the Longines PrimaLuna L8.111.6.87.2 is 6mm. This parameter represents the inner diameter of the attachment that accommodates the strap spring bar. A 6mm lug width is proportionate to the 26.50mm case diameter and requires straps with spring bars specifically designed for this dimension. Always verify that the spring bar penetrates smoothly into the lugs without forcing.
What is the best strap for the Longines PrimaLuna L8.111.6.87.2?
The optimal strap depends on intended use: natural black alligator provides formality and aesthetic compatibility with the yellow gold case; vegetable-tanned calf in cognac offers chromatic warmth and everyday versatility; shell cordovan ensures exceptional durability with profound patina development over time. We recommend against textile NATO straps, which create excessive visual contrast with yellow gold.
How do I change the strap on my Longines PrimaLuna L8.111.6.87.2?
Obtain a spring bar remover tool. Invert the watch and position the lever in the lower attachment slot to compress the internal spring, extracting the pin. Repeat on the second attachment. Verify that the new strap has 6mm spring bars with a depth between 1.2-1.5mm. Reinsert the pins by gently compressing until you hear a click indicating secure engagement.
Can I use an aftermarket compatible strap on my PrimaLuna L8.111.6.87.2?
Yes, 6mm aftermarket straps are entirely compatible with the PrimaLuna L8.111.6.87.2. Milano Straps offers straps in alligator, calf, shell cordovan, and rubber, customisable in length, initials, and thread colour, with rapid dispatch. The Casati Milano atelier creates bespoke straps with personal consultation and 18-month warranty.
How long does a leather strap last on the Longines PrimaLuna L8.111.6.87.2?
Durability depends on leather type and usage patterns. Alligator and vegetable-tanned calf withstand 3-5 years under moderate daily use conditions. Shell cordovan extends lifespan to 6-8 years owing to its structural density. A rubber strap exhibits indefinite durability but requires periodic cleaning. Humidity, perspiration, and sun exposure accelerate degradation; storage in a cool environment preserves fibre elasticity.
