Frequently asked questions

How do I change the strap on my Longines PrimaLuna L8.112.4.87.2?

Removing the strap requires a specific tool (spring bar tool) or the assistance of a watchmaker. Position the watch on a soft surface with the strap facing upward. Insert the tool into the small hole on each lug, press gently inward to release the pin, then slide the old strap away. Insert the new strap ensuring the springbars sit fully within the lug holes until you feel the click of closure.

How long does a leather strap last on a Longines PrimaLuna?

The longevity of a leather strap depends on material quality, frequency of use, and care. A high-quality alligator strap lasts approximately 5–7 years with moderate daily wear. Shell cordovan can exceed 10 years. Standard calf typically reaches 3–4 years. Ageing is natural and desirable in vegetable-tanned leathers: the patina that develops testifies to material authenticity. To extend lifespan, avoid prolonged exposure to water, humidity, and direct heat.

The next step

The right strap isn't chosen. It is built, together.
