The HydroConquest series is the ultimate diving watch for those who love the open seas. With a nod to the fearless men who conquer the oceans, these watches meet the strict standards of the discipline. They are water-resistant up to 300 meters, have a unidirectional turning bezel, and secure features like a screw-down case and crown, lateral protection, and a double security folding clasp with an integrated diving extension. These guarantees ensure uncompromising safety while maintaining the harmony of the underwater world. Longines has created the perfect blend of performance and elegance in this collection.
