This year, the HYDROCONQUEST GMT line has been enhanced with new models with 43mm diameter cases. Water-resistant up to 30 bar (300 meters), robust, and with a unidirectional rotating ceramic bezel, screw-in crown and screw-down case back, this collection is inspired by the world of water sports. Like the 41 mm models launched in 2023, the new HYDROCONQUEST GMTs feature an exclusive Longines movement with multiple time zones and offer a choice of colours and materials.
