History The Longines Flagship line was introduced in 1957 and quickly became one of the brand's most successful and recognizable dress watch collections. Known for elegant profiles and reliable mechanical movements, the Flagship represented Longines' commitment to refined traditional watchmaking during the mid-century period. The caliber 428 is a respected manual-wind movement that provided dependable service in many of the brand's slim dress models during the late 1960s and 1970s. Today, vintage Flagship models remain highly appreciated for their classic proportions and enduring design language. Payment and Shipping Payment must be completed within 1–3 days after purchase.
