The HYDROCONQUEST collection is a true benchmark for sports watches. The new models are powered by an exclusive Longines GMT movement that enables the time to be displayed for two time zones. It is equipped with a silicon balance-spring and innovative non-magnetic components that make this calibre more than 10 times more resistant to magnetic fields than the ISO 764 standard. The HydroConquest GMT is also distinguished by its 41 mm-diameter stainless steel case with screw-down back and crown. This model features a new unidirectional notched bezel in black ceramic with luminescent capsule. This dial is green. This version comes with a stainless-steel bracelet, or a green NATO strap made from recycled material.
