Longines HydroConquest 42mm Automatic Black Dial Milanese Mesh Steel Bracelet [L3.788.4.90.6]

The Longines HydroConquest 42mm Automatic [L3.788.4.90.6] delivers a bold and contemporary take on the Swiss dive watch, combining robust engineering with refined detailing. Its black lacquered polished dial offers exceptional clarity and contrast, enhanced by luminous markers and hands for optimal legibility in all environments. 

Built for performance, the watch features a 42 mm stainless steel case, unidirectional ceramic bezel, and screw-in crown, ensuring durability and precision under pressure. With 300 m (30 bar) water resistance and a scratch-resistant sapphire crystal with anti-reflective coating on both sides, it is engineered for serious underwater use while remaining versatile for daily wear. 

Powering the timepiece is the Longines Calibre L888.5 automatic movement, beating at 25,200 vibrations per hour and offering a substantial 72-hour power reserve. The inclusion of a monocrystalline silicon balance spring enhances resistance to magnetic fields and ensures long-term accuracy and 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 enhances comfort while elevating the watch into a versatile sport-luxury category—equally suited for business attire or weekend wear.
