History of Longines

Longines, founded in 1832 by Auguste Agassiz in Saint-Imier, Switzerland, is one of the oldest and most prestigious watchmaking houses in the world. Since its beginnings, Longines has been recognized for its pursuit of precision, technical innovation, and aesthetic elegance—values that remain its distinctive hallmark to this day. The company introduced its famous winged hourglass logo in 1889, becoming one of the first brands to register its emblem, which has strengthened its visual identity on a global scale.

During the early decades of the 20th century, and especially in the interwar period, Longines established itself as a leader in technical watchmaking, actively participating in the production of aviation chronometers and high-precision devices used by explorers, military personnel, and scientists. This golden age for the brand coincided with the rise of Art Deco, which greatly influenced the design of its watches, lending them a modern, stylized, and refined character.

The pocket watches produced by Longines in the 1920s and 1930s represent a pinnacle of its watchmaking expertise, combining cutting-edge technology of the time with exquisite aesthetics. Models like this one, made of gold and adorned with precious stones, were intended for a select clientele of aristocrats, businessmen, and prominent figures from the world of culture and politics.

Longines has always maintained a strong relationship with the world of sports timekeeping, serving as official timekeeper for many international events. Today, the brand is part of the Swatch Group but retains its original identity as a symbol of quality, timeless elegance, and Swiss reliability. Antique Longines pieces, especially those made in the first half of the 20th century, are highly prized in the collectors’ and historical watch markets for their precision, beauty, and legacy.
