Frequently asked questions

What is the lug width of the Longines PrimaLuna L8.115.5.61.7?

The lug width is 8mm, characteristic of dress watches with a 30.50mm case. Always verify measurement by positioning a calliper between the case lugs in parallel alignment.

Which strap should I choose for the Longines PrimaLuna L8.115.5.61.7?

We recommend Nile alligator, vegetable-tanned calf leather, or heavy-duty cotton NATO. Alligator emphasises formal elegance; calf develops a natural patina; NATO provides versatility. Selection depends on daily wear and personal style.

How do I change the strap on my Longines PrimaLuna?

Use a spring bar removal tool to compress the elastic pins securing the strap to the lugs. Position the watch on a flat surface, apply gentle pressure, and withdraw the old strap. Insert the new strap carefully, avoiding force that could damage the lug screws.

Can I fit an aftermarket strap to the Longines PrimaLuna?

Yes, provided the strap is designed for 8mm lugs. Milano Straps manufactures artisanal, customisable straps that fit the L8.115.5.61.7 perfectly, ensuring technical compliance without compromise.

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

With moderate daily wear, a quality calf strap lasts 18-36 months; alligator resists 24-48 months due to superior fibre consistency. Natural patina development is part of the charm. Milano Straps guarantees 18 months on all bespoke straps.
