History
Longines was founded in 1832 by Auguste Agassiz in Saint-Imier, Switzerland — its winged hourglass logo is the oldest registered trademark still in use in watchmaking. The brand's connection to water runs deep, having supplied instruments for expeditions and pioneered water-resistant cases in the 1930s. The HydroConquest launched in 2007 as Longines' dedicated sport-diving line, earning a reputation as the "gentleman's diver" — transitioning effortlessly from ocean to office while punching above its price in finishing and capability.
