Frequently asked questions

How do I change the strap on my Longines PrimaLuna L8.112.5.78.2?

Strap replacement requires minimal tools: a strap removal lever or precision spring bar tool. Position the watch with the lug side facing upward, locate the spring bar pin retaining the current strap, and gently depress the pin downward to release the strap. Repeat on the opposite side. To install the new strap, align the lugs with the spring bar holes and reinsert the pins until they click into place. If you lack confidence, consult an authorised service centre or the Casati Milano atelier for professional installation.

How long does a leather strap last on my Longines PrimaLuna L8.112.5.78.2?

The lifespan of a leather strap depends on tanning method, material grade, and frequency of wear. A vegetable-tanned alligator strap, if protected from intense sunlight and extreme humidity, may last 5-10 years without replacement. A smooth calf strap typically lasts 3-5 years, particularly with daily wear. Factors such as perspiration, prolonged UV exposure, and moisture accelerate deterioration. Proper maintenance—protection during rain, periodic cleaning, and conditioning with appropriate balms—significantly extends strap longevity.
