Longines was founded in 1832, and since that time it has become one of the superstars of fine Swiss watch manufacturing. They have outfitted some of the world’s most famous explorers—aviator Charles Lindbergh and polar explorer Roald Amundsen to name but two. 

Harnessing the will to make those deep dives takes fortitude. Ensuring you have a dependable watch upon your wrist takes an astuteness the value of which can not be measured.

The Longines Hydroconquest hands you the power to make those watery plunges with confidence. This piece sports a wonderful 300 m / 30 atm water resistance, screw-down winding crown, and screw-down case back.

The unidirectionally rotating bezel displays a bold, convenient dive scale with luminous dot. Applied hour markers glow bright with SuperLuminova as do the silvered polished hands, all of which make telling the time in low light a breeze.

Beneath the scratch-resistant sapphire crystal the bold and streamlined green sandblasted dial offers up a date window at 3 and a minute track in white running along the outer edge.

With the stainless steel case measuring 42 mm in diameter and 11.30 mm in height, it rests upon a stainless steel bracelet with a folding clasp. This quartz-driven timepiece features the Longines L157.3 movement.

From its robust construction to its sporty stylings, this Longines Hydroconquest will make a fantastic addition to your collection.
