Frequently asked questions
What is the lug width of the Longines PrimaLuna L8.112.5.93.2?
The lug width of the Longines PrimaLuna L8.112.5.93.2 is 7mm. This measurement represents the distance between the two attachment holes on the case and is essential for selecting a compatible strap. To verify it, position a digital calliper perpendicular to the two spring bar holes without applying pressure.
What is the best strap for the Longines PrimaLuna L8.112.5.93.2?
The ideal strap depends on intended use and personal preference. For vintage authenticity, we recommend alligator in cognac or dark brown tones, which complements the 30mm case proportion. For formal elegance, smooth leather in vegetable-tanned calf black. For sporty versatility, a NATO in canvas or an FKM rubber strap. All must feature 7mm lug width compatibility.
How do I change the strap on my Longines PrimaLuna L8.112.5.93.2?
Strap replacement is accomplished using spring bars. Utilise a dedicated spring bar removal tool to compress the small metal lug on the spring bar, thereby releasing the strap from the case. Insert the spring bar into the new 7mm strap, position it in the lug hole and allow the spring bar lug to re-engage. Repeat for both sides.
Can I use an aftermarket strap with my Longines L8.112.5.93.2?
Yes, any artisanal strap with 7mm lug width is perfectly compatible with the Longines PrimaLuna L8.112.5.93.2. Ensure that the attachment holes are circular and measure 1.2 to 1.5mm in diameter. Milanostraps offers 7mm straps in a broad range of materials and finishes, selected for aesthetic proportion with the 30mm case.
How long does a leather strap last on the Longines PrimaLuna L8.112.5.93.2?
Lifespan depends on material, usage and maintenance. A quality alligator or calf strap, subjected to moderate use, delivers 2-4 years of service. In vegetable tanning, leather enriches naturally in patina over time. FKM rubber straps offer greater longevity, up to 5-7 years. Regular maintenance—cleaning with a damp cloth and conditioning with specific creams—significantly extends strap lifespan.
