As diving watches par excellence, HydroConquest timepieces pay homage to those who dedicate themselves to conquering the oceans and to open-sea enthusiasts. They comply with strict requirements: 30 bar (300 m) water resistance, unidirectional turning bezel, screw-down case and crown, lateral crown protection, and a double-security folding clasp featuring an integrated diving extension. These robust safety guarantees harmonize with the silent world, combining performance and elegance in a uniquely Longines way.
