Strap for PrimaLuna Automatic 30 Pink Gold MOP

The lug width (ansa width) of the Longines PrimaLuna L8.113.8.87.6 is 8mm. This particular measurement derives from the proportional relationship between the 30mm case diameter and the overall lug-to-lug distance. To verify your lug width accurately, position a ruler perpendicular to the case at the attachment point of the strap and measure the clearance between the two spring bar holes. An incorrectly-sized strap would create installation difficulties and risk damage to both case and strap.

For a timepiece of this refinement, alligator remains the most harmonious aesthetic choice. A cognac or dark brown alligator strap creates a chromatic dialogue with the pink gold case, enhancing its warmth without visual competition. Alternatively, calf leather with fine, uniform grain or structured texture offers discreet elegance at a more accessible price point. For daily versatility, a NATO in linen or twisted cotton enables informal pairings whilst maintaining the visual proportion of the 8mm lug width. Your choice depends on personal style and intended use context.

Strap changing requires precision and appropriate tools. Obtain a spring bar tool with blunt ends to avoid scratching the case. Position the watch on a soft, stable surface with the dial facing downward. Gently insert the tool's end into the small hole of the upper lug, pushing upward until the internal spring retracts, releasing the lug end. Repeat with the lower lug. Once the old strap is removed, align the new strap's ends with the lug holes and, using the same procedure in reverse, secure the new strap ensuring the spring is fully seated.

Yes, the L8.113.8.87.6 is compatible with any 8mm lug width strap produced by third-party manufacturers, provided construction quality is elevated. Artisanal aftermarket straps guarantee aesthetics and durability comparable to genuine Longines straps. MilanoStraps offers a comprehensive selection of 8mm-compatible straps crafted with precious leathers and refined finishes, with customisation available in sizing, initials, and thread colour selection. The critical factor is selecting a reputable producer respecting construction standards appropriate for watches of this calibre.

Leather strap lifespan depends on multiple factors: frequency of wear, climate conditions, moisture and perspiration exposure, and leather quality itself. A strap crafted from premium alligator or calf leather, with appropriate tanning and well-executed stitching, typically lasts between 3–5 years with regular daily use. Vegetable-tanned leather tends to age more gracefully than chrome-tanned varieties, developing a desirable patina. Rubber and fabric straps (NATO) offer greater durability and moisture resistance. Proper maintenance—protection from excessive moisture, regular cleaning, thorough drying after perspiration exposure—significantly extends strap lifespan. MilanoStraps offers 18-month warranty on atelier-crafted straps, covering manufacturing defects.
