Strap for PrimaLuna Automatic 30 Pink Gold Diamond MOP

The Longines PrimaLuna L8.113.9.87.6 features 8mm lug width. This dimension is specific to this model and was carefully chosen by Longines to maintain elegant proportions on a 30mm case. To verify the compatibility of your strap, measure the internal width between the two lug holes using a digital calliper, keeping the measurement perpendicular to the lug shoulder.

Vegetable-tanned alligator represents the optimal choice for the rose gold PrimaLuna. The fine grain texture of the leather dialogues perfectly with the luminosity of rose gold, developing over time a patina that accompanies the case's character. Other excellent options include box calf for aesthetic simplicity, shell cordovan for bolder configurations, and linen NATO straps for warm seasons. The choice depends on your usage context and personal finishing preferences.

Strap replacement requires specific tools: a spring bar tool or dedicated strap changer. Position your watch on a soft surface to prevent scratching. Insert the spring bar tool into the small hole of the spring beneath the lug, gently lifting the spring towards the case centre. Once lifted, remove the lug from the previous strap. Repeat on the other side. Insert the new strap's lugs in the same manner, ensuring the spring clicks correctly into position. Proceed with care to avoid damaging the case or spring.

Standard aftermarket straps, commonly available from watch retailers, rarely fit correctly on the 8mm lugs of the PrimaLuna L8.113.9.87.6. Most industrially-produced straps are manufactured with wide tolerances, generating lateral movement on the case. We recommend seeking straps specifically dimensioned for 8mm lugs, available online at milanostraps.it, or opting for a custom strap crafted by the Casati Milano atelier, which guarantees perfect fit and integrated appearance.

A quality leather strap, made with vegetable tanning and crafted artisanally, has an average lifespan of 3–5 years under normal wear conditions. Longevity depends on exposure to humidity, perspiration, and temperature variations. A shell cordovan strap, owing to fibre density, may last beyond 5 years. A first-grade alligator strap maintains structural integrity up to 4–6 years. To extend your strap's life, avoid prolonged exposure to humidity and direct sunlight, and periodically apply protective creams with natural bases. The Casati Milano atelier provides an 18-month warranty on bespoke straps, covering manufacturing defects.
