Strap for Elegant Collection Automatic 27.2 Pink Gold - Diamond / White

The lug width of the Longines Elegant L4.378.9.12.4 is 20mm. This measurement is crucial for strap selection: use a flat gauge inserted between the spring bar posts and read the distance in millimetres without approximation.

Alligator leather in cognac shade is the dominant choice: the regular texture of the scales dialogues naturally with the case geometry, whilst the warm tone creates immediate chromatic synergy with rose gold. Valid alternatives include vegetable-tanned calf in bordeaux and shell cordovan in whiskey for those seeking pronounced character and visible patina.

The strap is replaced by removing the spring bar posts that lock the strap to the case lugs. Use a dedicated tool (spring bar tool) or consult a professional watchmaker: the Longines is a delicate timepiece and the operation admits no improvisation. The rose gold case, especially, requires maximum care to avoid scratches.

Yes, provided the strap is certified for 20mm lug width. Quality aftermarket straps (Italian artisanal, premium leather, hand-stitched construction) guarantee total compatibility and often superior comfort compared to the original, thanks to softer backing rubber and improved curves.

A quality artisanal alligator or calf strap, with proper maintenance (gentle cleaning, natural drying), lasts 3–5 years in daily wear. Shell cordovan, if preserved correctly, reaches 7–10 years: this leather ages nobly and improves aesthetically over time, developing unique and increasingly beautiful patina.
