The HydroConquest line, a true classic among sports watches, has been extended with models featuring a GMT function. Combining technical excellence and elegance, the HydroConquest GMT was inspired by the world of water sports and LONGINES’ historical expertise in the development of watches with multiple time zones. This GMT watch, water-resistant to 30 bar (300 m), features an exclusive LONGINES calibre equipped with a silicon hairspring and resistant to magnetic fields.
