Longines HydroConquest Automatic Sunray Black Dial Black Rubber Strap 41 mm [L3.781.3.58.9]

Inspired by the world of water sports, the Longines HydroConquest Automatic 41 mm [L3.781.3.58.9] balances serious dive-watch capability with refined detailing for everyday wear. The sunray black dial delivers bold contrast and clarity, enhanced by Swiss Super-LumiNova for confident legibility in changing conditions. A unidirectional rotating ceramic bezel underscores the watch’s purpose-built identity, elevated by a rose gold PVD-coated top ring that adds subtle warmth and distinction without compromising the tool-watch character.

Powered by a self-winding mechanical movement beating at 25,200 vibrations per hour and offering a power reserve up to approximately 72 hours, this timepiece is engineered for dependable precision. The stainless steel case features a screw-down crown and case back for water resistance to 30 bar (300 metres), while a scratch-resistant sapphire crystal with several layers of anti-reflective coating on both sides maintains crisp visibility. Finished on a black rubber strap with a double safety folding clasp and push-piece opening mechanism, the Longines HydroConquest [L3.781.3.58.9] is built for performance, comfort, and versatile daily wear — with the added refinement of a rose gold PVD-coated crown to mirror the bezel accent.
