A true classic among sports watches, the HYDROCONQUEST line has been expanded with new models featuring a sleek design and an exclusive Longines GMT movement. Combining technical excellence and elegance, two hallmarks of the winged hourglass brand, these new versions have taken inspiration from the world of water sports, while drawing on Longines' historic expertise in developing watches with multiple time zones.

Longines is expanding its HydroConquest line with new variations featuring a GMT complication, a first for this emblematic collection launched in 2007. This function allows the time to be displayed simultaneously in two time zones. This complication is linked to a rich heritage: Longines introduced the concept on a wristwatch as early as 1925.

The HydroConquest GMT combines this function, useful to all travellers, with the underwater sports codes that personify it. It's aimed at modern-day adventurers who love discovery, and at demanding sportsmen and women, and will accompany them wherever they go.

For this new generation of watches, Longines has fused retro-inspired design with the latest technological advances. The 41 mm diameter screw-down stainless-steel case back has been redesigned. It features the exclusive new Longines GMT calibre equipped with a silicon balance-spring and innovative components in non-magnetic materials. This movement is ten times more resistant to magnetic fields than the ISO 764 benchmark standard. It is extremely precise and has a power reserve of up to 72 hours.

The HydroConquest GMT is also distinguished by its new unidirectional notched ceramic bezel fitted with a luminescent capsule and a screw-in crown. The alternating polished and satin-finished surfaces add a sophistication and elegance to these new models. The green, brown, black and blue sunray dials are enhanced by a two-tone24-hour scale. The gilt or silvered polished hands and hour-markers are coated with Super-LumiNova®, making them easy to read in any circumstances. They are round at 6 and 9 o'clock and triangular at 12 o’clock. At 3 o'clock, the date window shows the date. The arrow-shaped GMT indicator matches the colour of the dial decals.

Water-resistant to 30 bar (300 metres), the HydroConquest GMT models are fitted with a stainless-steel bracelet with completely redesigned H-shaped links. It is also, for the first time at Longines, equipped with a micro-adjusting clasp. Complementing the colours of the dials, the new watches are also available with a blue or black rubber strap with micro-adjusting folding clasp for perfect fit and comfort. A NATO bracelet in khaki-green or beige is also available. 

The new HydroConquest GMT is perfect for every adventure. The world is truly your playground!
