Frequently asked questions
What is the lug width of the Longines PrimaLuna L8.113.8.83.6?
The lug width of the Longines PrimaLuna L8.113.8.83.6 is 8mm. This dimension is determined by the distance between the spring bar slots on the 30mm rose gold case. Precise measurement using a digital calliper, positioned on the inner wall of the spring, is essential to ensure complete compatibility with aftermarket straps.
Which strap material is most appropriate for the Longines PrimaLuna L8.113.8.83.6?
For the PrimaLuna L8.113.8.83.6, we recommend alligator straps (structured grain in brown or cognac tones) for formal elegance, French calf with vegetable tanning for aesthetic evolution over time, or smooth rubber fitted with rose gold deployante for contemporary versatility. Choice depends on usage profile: formal, daily, or alternating wear. Alligator represents the compromise-free solution that naturally complements the warm tonality of rose gold.
How do I change the strap on my Longines PrimaLuna L8.113.8.83.6?
Strap replacement on the PrimaLuna L8.113.8.83.6 is accomplished by removing the spring bars. Position the watch on a soft surface. Use a spring bar tool to gently press the spring bar on one side, creating sufficient clearance to extract the pin. Repeat on the other side. Insert the new 8mm strap by aligning the pins with the lugs, pressing gently until you hear the locking click. Avoid abrupt movements that could damage the springs.
Can I use an aftermarket strap compatible with my Longines PrimaLuna L8.113.8.83.6?
Yes, absolutely. Any artisanal strap with 8mm lug width is compatible with the PrimaLuna L8.113.8.83.6, provided it meets correct construction standards. Aftermarket options in alligator, calf, shell cordovan, or vegetable-tanned leather offer superior aesthetic opportunities compared to the original strap, enabling chromatic and material customisation consistent with your usage profile.
How long does a leather strap last on a watch like the Longines PrimaLuna L8.113.8.83.6?
Leather strap durability depends on frequency of use, moisture exposure, and material quality. An artisanal strap in quality alligator or calf, worn daily, offers structural resistance of 3–5 years. Vegetable-tanned leather offers superior longevity, reaching 5–7 years with proper care. Visible wear (creasing, patina development) does not compromise functionality but signals opportune maintenance. Casati Milano provides 18-month warranty on all custom-made straps.
