In 2024, the HydroConquest collection expanded its repertoire with new models with a diameter of 43 mm. The case of this latest generation is made of alternating polished and satin-finished stainless steel with a screw-down back. It houses the exclusive Longines GMT calibre L844.5, which is equipped with a silicon balance spring and innovative components made from non-magnetic materials.
The fresh HydroConquest GMT versions are available in black, blue or green and feature a sapphire crystal with several layers of anti-reflective coating.
