Description
The HYDROCONQUEST collection is a hallmark of sports watches. Its new models are equipped with the exclusive Longines GMT movement, allowing for simultaneous display of two time zones. The calibre is fitted with a silicon balance-spring and non-magnetic components that render it more than 10 times more resilient to magnetic fields than ISO 764 requirements.
The 41mm stainless steel case of the HydroConquest GMT includes a screw-down back and crown, and is further complemented by a brown ceramic unidirectional notched bezel with luminous markers. The brown dial is available with either a stainless steel bracelet or a beige NATO strap crafted from recycled materials.
