Strap for PrimaLuna Automatic 26.5 Yellow Gold Funky MOP

The lug width of the Longines PrimaLuna L8.111.6.83.6 is 6mm. This measurement represents the distance between the case attachment pins and is the essential parameter for aftermarket strap compatibility. To verify correctly, measure from the centre of one pin to the other perpendicularly to the case.

For the yellow gold PrimaLuna, we recommend medium brown alligator with natural patina, which harmonises with the warmth of the precious metal. Alternatively, calf leather finished with vegetable tanning in deep burgundy or grey-beige taupe. Pure white or glossy black are discouraged, as they contradict the feminine elegance of the model.

Strap replacement requires a spring bar tool to remove the elastic pins from the case lugs. Position the tool under the pin, apply upward pressure and extract the old strap. Insert the new strap's pins into the same housings and verify the absence of lateral play. If you do not possess the tool, consult a goldsmith or Casati Milano atelier for professional replacement.

Yes, all artisanal straps with specific 6mm lug width are compatible with the L8.111.6.83.6. Ensure the strap has been constructed with precise dimensional tolerance—the pin must fit snugly without lateral play. Custom-made straps from specialised ateliers guarantee certified compatibility and superior quality over industrial production.

A premium leather strap (alligator, calf, shell cordovan) has an average lifespan of 3–5 years, varying according to use and climate. Leather exposed to frequent perspiration ages more rapidly. Casati Milano atelier provides an 18-month warranty and offers regeneration and colour restoration services to extend strap life beyond replacement.
