HydroConquest models are dive watches par excellence, paying homage to ocean conquerors and open-sea enthusiasts alike. They meet the rigorous demands of the sport with water resistance up to 30 bar (300 metres), a unidirectional turning bezel, screw-down case and crown, protective crown guards, and a double safety folding clasp with built-in diving extension. These solid safety features are in perfect harmony with the quiet underwater world, reflecting Longines' unique fusion of performance and elegance.
