Frequently asked questions

What is the lug width of the Longines PrimaLuna L8.110.9.78.2?

The lug width of the Longines PrimaLuna L8.110.9.78.2 is precisely 6 millimetres. This measurement is critical for ensuring compatibility with any aftermarket strap. To verify, measure the distance between the two spring bars protruding from the case lugs—the value must be exactly 6 mm.

Which strap material best suits the Longines PrimaLuna L8.110.9.78.2 in pink gold?

For the PrimaLuna L8.110.9.78.2, alligator remains the most refined and traditional choice, thanks to its regular grain pattern that complements rather than competes with the case's elegance. Fine-grained calf represents an excellent alternative, developing natural patina over time. For contemporary wear, high-density technical textiles are equally appropriate, provided they are handcrafted and meticulously sewn.

How should I change the strap on my Longines PrimaLuna L8.110.9.78.2 without damaging the spring bars?

The spring bars on the PrimaLuna L8.110.9.78.2 are delicate given the reduced 6 mm diameter. We recommend using a dedicated spring bar tool with rounded, not sharp, tips. Press the bar gently towards the case centre—it should yield with light pressure. If resistance is significant, consult a professional watchmaker to avoid damage.

Can I install an aftermarket 6 mm strap on my Longines PrimaLuna L8.110.9.78.2?

Yes, provided the strap has been specifically engineered for a 6 mm lug width. Many generic straps do not meet this specification, causing looseness or micro-damage to the spring bars. Always verify exact compatibility with reference L8.110.9.78.2 with the seller before ordering.

How long does a leather strap last on a Longines PrimaLuna ladies' watch such as the L8.110.9.78.2?

Durability depends on usage and material quality. A handcrafted alligator or calf strap of good quality maintains structural integrity for 5-8 years in daily wear, developing authentic patina. Wear accelerates with continuous exposure to moisture and perspiration. Application of natural conditioners every 6-12 months significantly extends the strap's lifespan.
