The Longines HydroConquest GMT [L3.790.4.56.9] automatic masterfully combines robust diver performance with the added utility of a dual-time GMT function, making it an exceptional choice for sport-watch enthusiasts and global travellers alike. Its 43 mm stainless steel case is paired with a unidirectional ceramic bezel, offering durability and resistance to everyday wear while delivering 300 m water resistance — a hallmark of the HydroConquest family’s professional-grade capability.

The sunray black dial conveys dramatic depth and contrast, punctuated by applied luminescent indexes and a dedicated GMT hand that enables simultaneous tracking of a second time zone. A date window enhances everyday convenience, while the scratch-resistant sapphire crystal with anti-reflective coating ensures lasting clarity under varied lighting conditions.

Powered by Longines’ automatic GMT calibre with a silicon balance-spring and up to 72 hours of power reserve, this timepiece fuses precision Swiss engineering with practical performance. Secured with a black rubber strap featuring a double security folding clasp and micro-adjustment system, the HydroConquest GMT delivers comfort and confidence on the wrist, whether on land or at sea.
