The PrimaLuna L8.110.8.16.6 (aka: L81108166), seen from the bench

The Longines PrimaLuna L8.110.8.16.6 is a contemporary evolution of an iconic women's fine watchmaking model, combining Swiss tradition with lunar design. Housed in a 26.5mm rose gold case with a white mother-of-pearl dial, the watch features the manual-winding L250 caliber movement, moon phase display, and water resistance to 30 meters. The strap width is 6mm, proportioned to complement the delicate case and requiring careful aftermarket selection.

Frequently asked questions

What is the lug width of the Longines PrimaLuna L8.110.8.16.6?

The lug width of the Longines PrimaLuna L8.110.8.16.6 is 6 millimetres. This dimension is specific to the 26.5mm case and requires proportionate straps to avoid unwanted gaps or structural stress on the lugs.

Which strap material pairs best with the rose gold PrimaLuna?

Alligator leather in cognac or chocolate tones is the natural pairing for rose gold: the geometric grain creates tactile contrast that emphasises the smoothness of gold, whilst developing a dignified patina over time. Alternatively, vegetable-tanned calf offers discretion, and burgundy shell cordovan adds depth without aggression.

How do I correctly change the strap on the Longines PrimaLuna?

Use a spring bar removal tool to gently lift the elastic pin from one side only. Do not force: the pin will snap out naturally. Insert the new strap by aligning one lug first, then lower the other whilst engaging the pin into the hole. Verify the pin is completely seated to prevent accidental loss.

Are there compatible aftermarket straps available for the 6mm lug width?

Yes. Milano Straps offers a collection of 6mm-compatible straps ready for shipment, customisable in length, initials, and stitching thread colour. Casati Milano atelier, by appointment, creates bespoke straps with personal leather selection and 18-month warranty.

How long does a natural leather strap last on a daily-worn timepiece?

With moderate use, quality alligator or calf leather lasts 3–5 years. Exposure to humidity, perspiration, and sunlight accelerates ageing. Shell cordovan, thanks to its molecular structure, is more moisture-resistant. Vegetable tanning develops authentic patina but requires periodic maintenance with specific creams.
