Frequently asked questions

What is the lug width of the Longines PrimaLuna L8.112.5.16.6?

The lug width of the Longines PrimaLuna L8.112.5.16.6 is 7mm. This measurement represents the distance between the two internal attachment pins of the case. A strap designed for this width must fit with millimetre precision, without excessive play or forcing. On milanostraps.it you will find the entire collection of compatible 7mm straps, ready for dispatch.

What is the best strap material for the Longines PrimaLuna?

The Longines PrimaLuna L8.112.5.16.6 is suited to multiple material choices depending on use. For maximum elegance we recommend alligator (natural texture, evolving patina over time) or shell cordovan (extraordinary chromatic density, lustrous patina). For refined daily wear, vegetable-tanned calf offers ethical aesthetics. For absolute practicality, FKM rubber on a steel deployant ensures comfort and minimal maintenance. Your choice depends on the intended wearing occasion.

How do I change the strap on the Longines PrimaLuna?

Strap replacement requires a spring bar tool (lever-type instrument) and adequate lighting. Position the watch with the lugs facing you. Insert the fine tip of the spring bar tool into the lateral hole of the lug, applying gentle pressure to release the internal spring. The lug will retract: extract it from the case pins. Repeat for the lower lug. Mount the new strap by reversing the procedure. If you prefer to avoid DIY, Casati Milano atelier offers professional strap change with supervision.

Is an aftermarket strap compatible with the Longines PrimaLuna L8.112.5.16.6?

Yes, any strap designed for 7mm lug width is compatible with the Longines PrimaLuna L8.112.5.16.6, provided the lug width is measured correctly. Generic 7mm straps may exhibit excessive manufacturing tolerances (play or friction). At milanostraps.it, 7mm straps are constructed with tight tolerances and certified compatible with your model. Choosing bespoke straps ensures millimetre precision and carefully selected materials.

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

A natural leather strap (alligator, calf, cordovan) subjected to daily wear typically lasts 3-5 years before replacement is needed. Factors that extend longevity: avoid prolonged exposure to moisture, do not wear during bathing/showering, alternate with other straps (rest allows materials to dry completely). With proper maintenance (conditioning with specific creams, periodic cleaning), lifespan can extend to 6-7 years. Casati Milano atelier provides an 18-month guarantee on every bespoke strap and offers specialist maintenance services.
