Longines HydroConquest 42mm Automatic Black Dial Milanese Mesh Steel Bracelet [L3.788.4.70.6]

The Longines HydroConquest 42mm Automatic [L3.788.4.70.6] delivers a bold and contemporary expression of the modern dive watch, combining professional-grade performance with refined design. Its black lacquered polished dialensures exceptional legibility, enhanced by luminous markers and hands for visibility in all conditions.

Engineered for demanding environments, the watch features a 42 mm stainless steel case, unidirectional ceramic bezel, and screw-in crown, providing durability and precision. With 300 m (30 bar) water resistance and a scratch-resistant sapphire crystal with anti-reflective coating on both sides, it is built for both underwater exploration and everyday wear.

At its core is the Longines Calibre L888.5 automatic movement, offering a robust 72-hour power reserve and enhanced accuracy through a silicon balance spring, improving resistance to magnetic interference and long-term reliability.

This reference is distinguished by its Milanese stainless steel bracelet, also known as a mesh bracelet, which introduces a more fluid and refined aesthetic compared to traditional link bracelets. The finely woven construction provides exceptional comfort while elevating the watch into a versatile sport-luxury category—equally suited for business attire or relaxed weekend wear.
