A Timeless Longines Flagship Ref. 3403
If you’ve been on the hunt for a Longines Flagship Ref. 3403 that feels as honest as it looks, this circa 1960 example in 9k gold might just be the one. At 35 mm, it wears comfortably under a cuff yet still has presence—perfect for anyone who prefers quiet confidence over flash.
A Quick Flagship History
Introduced in the late 1950s, Longines’s Flagship line married robust automatic movements with clean, dressy designs. The Ref. 3403, powered by the dependable Calibre 340, quickly became a favourite for everyday elegance.
Key Highlights
  • 35 mm 9k Gold Case: Solid gold with a light, honest patina that comes from six decades of gentle wear.
  • Automatic Calibre 340: Smooth, reliable winding every time you wear it—no battery, no fuss.
  • Classic Dial & Hands: Simple baton indices and dauphine hands on a softly aged silver dial; legible and timeless.
  • Ideal Vintage Size: At 35 mm, it’s right between too-big and too-small—versatile for any wrist.
Whether you’re slipping it on for a day at the office or a weekend brunch, this Longines Flagship Ref. 3403 has the kind of understated charm that never goes out of style. If you’d like to see more photos or talk details, just give us a shout.
