The HydroConquest series is a tribute to men who have dedicated themselves to conquering the oceans and to open-sea enthusiasts. As diving watches par excellence, they meet strict requirements: 30-bar water resistance, unidirectional rotating bezel, screw-down case and crown, lateral crown protection, and double security folding clasp with diving extension. These rigorous safety assurances fit perfectly with the silent world's harmony, offering Longines' unique combination of performance and elegance.
