Strap for Elegant Collection Automatic 27.2 Pink Gold / Diamond / MOP

The lug width of the Longines Elegant L4.378.9.87.0 is 18 mm. This measurement is essential for selecting compatible straps: ensure that your strap has precisely 18 mm between the spring bar posts. A tolerance of ±0.5 mm is acceptable, but precision is critical to prevent slippage.

For the Longines Elegant L4.378.9.87.0 in rose gold, dark alligator, waxed calf in cognac tones, or vegetable-tanned leather in hazelnut shades are ideal. These materials respect the classical elegance of the case without competing chromatically. Alligator provides sophisticated texture, whilst waxed calf develops natural patina over time.

Use a spring bar tool to gently lift the V-spring mechanisms at the lug ends. Remove the old strap and insert the new one, ensuring the spring bars click securely into the case slots. Verify proper seating before wearing the watch. If uncertain, consult a certified watchmaker.

Yes, provided the strap features an 18 mm lug width. Quality aftermarket straps (in alligator, shell cordovan, or Italian leather) are fully compatible with the L4.378.9.87.0. Select reputable brands that guarantee lug finishing and construction quality meeting Swiss standards.

A high-quality leather strap (alligator, shell cordovan, vegetable-tanned) typically lasts 3–5 years with daily wear, developing noble patina. Longevity depends on humidity, perspiration, and frequency of use. A protected strap, worn occasionally, may exceed 7 years. Periodic maintenance (cleaning, hydrophobic treatment) extends useful life.
