The history of the Longines brand traces back to 1832 when Auguste Agassiz established a watchmaking concern in Saint-Imier, Switzerland. Ernest Francillon, Agassiz's nephew, played a pivotal role in steering the family business towards innovation and success. In 1867, Francillon inaugurated the first factory integrating all watchmaking procedures under one roof, and he introduced the winged hourglass logo, symbolizing precision and excellence, engraved on all products. The brand was named Longines, derived from the locality's name, meaning "long meadows" in the regional dialect. The Longines Museum in Saint-Imier, renovated in 2012, showcases the brand's rich heritage, displaying iconic timepieces, navigation and timekeeping instruments, and archival documents. Longines' values of tradition, innovation, adventure, sport, and elegance are reflected in the museum's exhibits, highlighting the brand's significant contributions to exploration, aviation, sport timing technology, and refined design. The museum serves as a testament to Longines' enduring legacy in Swiss watchmaking and its profound impact on industrial and regional heritage.
