Strap for PrimaLuna Automatic 30 Pink Gold Leather

The lug width of the Longines PrimaLuna L8.113.8.78.2 is exactly 8mm. This measurement is precise and does not permit variation: a strap must fit snugly to both lugs without mechanical play. To verify compatibility, measure the distance between the two lugs using a digital calliper at the point of maximum depth.

For a PrimaLuna in rose gold, dark brown alligator (mahogany) or noble calf leather in tobacco hue are the most coherent choices. Alligator features a regular grain that does not compete with the case's luminosity; calf with vegetable tanning develops natural patina over time that harmonises with rose gold. Shell cordovan in burgundy is a valid alternative for those seeking superior density and generational durability.

To change the strap, position the watch on a soft surface and locate the two lugs. Using a fine-pointed tool – a professional spring bar tool – flex the internal spring of the lug, extract the stud, and remove the old strap. Insert the new strap by aligning the holes with the attachment points, reposition the stud by pushing until you hear a click of security. Verify the strap is stable before wearing.

Yes, provided the strap rigorously respects the 8mm lug width and is crafted by specialists who guarantee precise constructive tolerances. Milano Straps supplies verified 8mm straps compatible with your Longines, available in various leathers and finishes. We recommend always straps with reinforced anchor points to protect the delicate lugs of a rose gold case.

The lifespan of a leather strap varies according to material type, frequency of wear, and environmental conditions. Quality alligator or shell cordovan can last 5-8 years with daily wear; noble calf withstands 3-5 years. Exposure to perspiration, humidity, and UV rays accelerates ageing. Casati Milano guarantees 18 months on bespoke straps, covering constructive defects. Periodic strap renewal is part of standard watch maintenance.
