Strap for PrimaLuna Automatic 26.5 Pink Gold

The lug width of the Longines PrimaLuna L8.111.8.78.6 is 6mm, an uncommon specification in luxury watchmaking. This dimension is determined by the delicate case geometry and Longines' intentional construction proportions. To verify the correct measurement, use a digital calliper and measure the distance between the inner edge of the right lug and the inner edge of the left lug, with the watch positioned sideways.

The best strap for the Longines PrimaLuna L8.111.8.78.6 is alligator leather in neutral tones such as chocolate or black, which enhances the rose gold case's prestige without visual competition. Refined alternatives include vegetable-tanned calf that develops patina over time, or a natural cotton NATO for more casual contexts. The choice must respect the delicate aesthetic balance of the model, maintaining a restrained colour palette.

To change the strap on your Longines PrimaLuna L8.111.8.78.6, use a spring bar tool with extreme care, given the fragility of the 26.5mm case. Place the watch on a soft surface, access the case flank, and press the small knob of the tool against the internal spring of the pin to release the lug. Extract the pin completely, apply the new strap and reinsert the pin until it clicks. It is advisable to have this operation performed by a specialist at a dedicated atelier.

Yes, you can use an aftermarket strap specifically made for the 6mm lug width. Milano Straps offers a dedicated collection of compatible straps in alligator, calf and other leathers, customisable in length, colour, initials and finishing types. To ensure maximum aesthetic compatibility with the rose gold case, it is advisable to choose noble leathers and finishes that respect the model's constructive code.

A quality leather strap (alligator or calf) on a Longines PrimaLuna L8.111.8.78.6 lasts on average 3-5 years with daily wear, provided proper maintenance. Longevity depends on moisture exposure, cleaning regularity and tanning type. Straps made with vegetable tanning tend to develop a natural patina that prolongs the perception of elegance over time. Milano Straps provides an 18-month warranty on all custom straps, with the option of preventive replacement before critical wear.
