Strap for PrimaLuna Automatic 26.5 Stainless Steel / White / Bracelet

The Longines PrimaLuna L8.111.4.16.6 features a lug width of 6mm. This narrow dimension is consistent with the compact 26.5mm case diameter and is typical of luxury women's watchmaking. The measurement must be taken horizontally between the attachment points, excluding the case thickness.

Premium alligator is the natural choice for this model, thanks to its geometric grain texture that maintains visual coherence with the case's minimalist design. An equally elegant alternative is cordovan in dark tones, which offers chromatic depth and structural rigidity ideal for a stainless steel case. Vegetable-tanned calf leather represents a more casual but still refined option.

Changing the strap on the Longines PrimaLuna L8.111.4.16.6 requires a spring bar remover tool, a small flat instrument. Insert the remover between the case and the lug attachment, applying gentle pressure to compress the internal spring. Once the spring is compressed, the strap releases. The reverse procedure allows you to install the new strap. Given the small size of the lugs (6mm), proceed with care to avoid scratching the case finishing.

Yes, any strap with a 6mm lug width is mechanically compatible with the Longines PrimaLuna L8.111.4.16.6. However, aesthetic compatibility depends on style: it is advisable to choose materials and colours that maintain coherence with the case's minimalist geometry in stainless steel and its compact 26.5mm diameter. Overly thick or brightly coloured straps could compromise the visual proportion of the piece.

A high-quality natural leather strap, such as alligator or cordovan, typically lasts 3–5 years under daily wear conditions. Longevity depends on factors such as humidity exposure, frequency of use, and routine care. The leather develops a natural patina over time that increases aesthetic appeal. Periodic maintenance with specialized oils or simple cleaning with a damp cloth keeps the strap in optimal condition and extends its lifespan.
