The PrimaLuna L8.110.5.78.6 (aka: L81105786), seen from the bench

The Longines PrimaLuna L8.110.5.78.6 is a women's watch featuring a 26.50mm stainless steel and rose gold case from the PrimaLuna collection. It houses the automatic Longines calibre L250 movement with date window and sapphire crystal. The dial is available in white, grey, or champagne shades with hour, minute, and second subdials. The distinctive 6mm lug width is a specific requirement due to the compact case proportions and integrated lugs, making standard aftermarket straps incompatible with this model.

Frequently asked questions

What is the lug width of the Longines PrimaLuna L8.110.5.78.6?

The lug width (measure ansa) of the Longines PrimaLuna L8.110.5.78.6 is 6mm. This measurement refers to the internal distance between the two sides of the lug. Given that this is a rare dimension, it is essential to verify it accurately before ordering an aftermarket strap to avoid compatibility issues.

What is the best strap for the Longines PrimaLuna L8.110.5.78.6?

Alligator leather in cognac or black tones represents the most aesthetically appropriate choice, enhancing the jewellery character of the model and the two-tone steel-rose gold case. Alternatively, vegetable-tanned calf leather in hazelnut offers versatility without compromising construction quality. The choice depends on intended use and your specific dial variant.

How do you change the strap on a Longines PrimaLuna L8.110.5.78.6?

Strap replacement is performed using a spring bar tool. Position the watch on a soft surface and apply gentle pressure to the internal spring of the lug with the tool, removing the pin. Proceed with care: 6mm lugs are smaller and require greater precision than standard models. If you are inexperienced, consult a qualified watchmaker.

Is there an aftermarket strap compatible with the Longines PrimaLuna L8.110.5.78.6?

Yes. The Longines PrimaLuna L8.110.5.78.6 is compatible with all straps in the 6mm collection. Milano Straps offers a complete range of straps in alligator, calf, rubber and fabric, all customisable in length, initials and stitching type. Shipping is prompt and compatibility is guaranteed.

How long does a leather strap last on a Longines PrimaLuna L8.110.5.78.6?

The lifespan of a leather strap depends on usage and maintenance. Quality alligator or calf, subject to regular maintenance (occasional cleaning and annual conditioning), can last 3–5 years. Straps crafted from vegetable-tanned leather develop a natural patina over time, increasing their character. Milano Straps warranty covers manufacturing defects for 18 months.
