The strap for this watch is made to measure
On the Longines Elegant the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

Which strap is most suitable for the Longines Elegant L4.378.9.12.4 in rose gold?
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.
How do you change the strap on the Longines Elegant L4.378.9.12.4?
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.
What is the average lifespan of a leather strap on a Longines Elegant?
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.
