Description
The Longines HydroConquest, reference L3.780.3, is a purpose-built dive watch that combines robust underwater capability with a refined two-tone aesthetic. Its 39mm round stainless steel case gives it a balanced wrist presence that suits both daily wear and professional-style use, while the unidirectional rotating bezel reinforces its sports-watch function. The bezel is fitted with a scratch-resistant ceramic insert, a material chosen for its durability, resistance to fading, and clean, polished appearance.
The bracelet is constructed from high-grade stainless steel outer links with pink gold PVD-coated center links, creating a distinctive contrast that adds warmth and visual interest to the watch’s otherwise technical design. It also includes an integrated fold-out extension, allowing the watch to fit comfortably over a thick wetsuit, which is an important practical feature for diving. The sunray grey dial has an elegant yet highly legible layout, with large Arabic numerals and generous applications of Swiss Super-LumiNova® designed to remain clear in low-light and underwater conditions. A scratch-resistant sapphire crystal protects the dial and is treated with multiple layers of anti-reflective coating on both sides to improve visibility.
The crown is screw-down and finished in pink gold PVD to match the bracelet accents, further reinforcing the watch’s two-tone design while supporting its water resistance. The solid case back adds to the watch’s sturdy construction and sealed profile. Inside, the HydroConquest is powered by the Longines Calibre L888, a self-winding automatic movement that offers an impressive 72-hour power reserve. Rated water resistant to 300 metres, this model is built to deliver dependable performance in demanding aquatic environments while still maintaining the polished styling associated with Longines.
