Frequently asked questions
What is the lug width of the Longines PrimaLuna L8.110.5.90.6?
The lug width of the Longines PrimaLuna L8.110.5.90.6 is 6 millimetres. This specification defines the distance between the metal spring bars attached to the case lugs where the strap connects. It is essential to verify this measurement before purchasing an aftermarket strap, as an incorrect lug width will not be mechanically compatible with the case.
Which strap pairs best with the Longines PrimaLuna L8.110.5.90.6?
For the Longines PrimaLuna L8.110.5.90.6, alligator leather in chocolate brown tones or vegetable-tanned calf represent ideal choices. Alligator emphasises the natural geometry through its characteristic scales, whilst calf develops an intriguing patina over time. For more versatile daily use, cotton or silk NATO straps maintain elegance without sacrificing practicality. The choice depends on context of use and personal maintenance preferences.
How do I change the strap on my Longines PrimaLuna L8.110.5.90.6?
Strap replacement is accomplished by extracting the spring bars that connect the strap to the case. Use a proper spring bar tool to gently push the bar inward, releasing one end of the strap at a time. Once the old strap is removed, align the new strap's holes with the spring bar positions and reinsert the bars until they click securely into place. Avoid forcing, as this may damage the delicate case lugs.
Can I use aftermarket straps on this Longines model?
Yes, aftermarket straps are fully compatible provided they feature the correct 6-millimetre lug width. Quality straps crafted by artisan makers often feature superior materials (alligator, shell cordovan, vegetable-tanned calf) compared to original factory straps, and are customisable in length, finishing, and thread colour to suit individual wrist dimensions and aesthetic preferences.
How long does a natural leather strap last on the Longines PrimaLuna?
The lifespan of a natural leather strap depends on usage frequency, exposure to moisture, and the inherent quality of the leather itself. A well-crafted alligator or vegetable-tanned calf strap, worn with moderate regularity (not continuously daily), typically lasts 3-5 years before showing significant wear signs. Proper maintenance — immediate drying after moisture exposure, avoiding direct contact with salt perspiration — can substantially extend the strap's useful life.
