Frequently asked questions

What is the lug width of the Longines PrimaLuna L8.112.5.94.6?

The lug width of the Longines PrimaLuna L8.112.5.94.6 is 7mm. This is a non-standard measurement that requires careful strap selection. To verify, place a digital calliper perpendicular to the case lug, measuring the internal distance between lugs at the midpoint of the lug thickness.

Which strap material is best suited for the Longines PrimaLuna L8.112.5.94.6?

For the PrimaLuna L8.112.5.94.6, we recommend African alligator in neutral tones (black, cognac brown) for formal occasions, or vegetable-tanned calf for a sophisticated, sustainable approach. Shell cordovan in burgundy offers a vintage-inflected alternative. NATO straps and rubber are discouraged, as their sporting character contradicts the watch's formal identity.

How do I change the strap on a Longines PrimaLuna L8.112.5.94.6?

Strap replacement requires a spring bar tool or dedicated lug bar remover. Place the watch on a stable surface, locate the metal pin (spring bar) beneath the lug, compress the lateral spring, and gently pull the pin outward. This releases the old strap. Insert the new strap into the lug slot, position the spring bar, and allow the spring to re-engage. Repeat for the opposite lug.

Which aftermarket straps are compatible with the Longines PrimaLuna L8.112.5.94.6?

Any strap with a 7mm lug width and standard spring bar fitment is compatible. Milano Straps offers a comprehensive collection of 7mm straps in alligator, vegetable-tanned calf, shell cordovan and other materials, customisable in length, initials, and stitching thread. Atelier Casati Milano also crafts bespoke straps with direct consultation and an 18-month warranty.

What is the expected lifespan of a leather strap for the Longines PrimaLuna L8.112.5.94.6?

A premium leather strap (alligator, vegetable-tanned calf, shell cordovan) worn daily typically lasts 3-5 years, depending on usage frequency and care. Constant exposure to perspiration, moisture, and sunlight accelerates deterioration. High-grade alligator straps may reach 5-7 years with regular maintenance. Casati Milano's 18-month warranty covers manufacturing defects and stitching, not natural leather wear.
