Longines HydroConquest GMT 41mm Black (Ref. L3.790.4.56.6)

The Longines HydroConquest GMT takes the rugged capability of the iconic HydroConquest collection and adds practical multi-time-zone functionality, creating a luxury sports watch equally suited for diving, traveling, and everyday wear. Its striking sunray black dial, matching black ceramic bezel, and stainless steel construction give the watch a sophisticated yet purposeful appearance. The 41mm stainless steel case offers substantial wrist presence while maintaining excellent proportions and versatility. A scratch-resistant sapphire crystal with multiple layers of anti-reflective coating on both sides provides exceptional clarity, while the screw-down crown, unidirectional rotating ceramic bezel, and impressive 300 meters of water resistance preserve the professional dive-watch credentials of the HydroConquest collection. At the heart of the watch is the exclusive Longines Calibre L844 automatic GMT movement. Equipped with a silicon balance spring and enhanced resistance to magnetic fields, the movement operates at 25,200 vibrations per hour and provides an impressive 72-hour power reserve. Its GMT functionality allows an additional time zone to be tracked, making the HydroConquest GMT an excellent companion for frequent travelers.
