Longines HydroConquest quartz black dial steel bracelet 42 mm

The story behind it

Since its launch in 2007, the HydroConquest collection has embodied a distinctive vision of the sports watch according to Longines: a timepiece capable of combining technical performance with natural elegance. True to the heritage of the Conquest line, the first collection registered by the maison in 1954, it belongs to a horological tradition where every detail is designed to accompany daily life with precision and purpose.

With the HydroConquest, this ambition takes on a new dimension. Inspired by the aquatic world while retaining a strong urban vocation, it has established itself for nearly two decades as a benchmark among contemporary sports watches, capable of combining robustness, legibility, and style without compromise.

In 2026, Longines unveils a fully reinterpreted new generation of its icon. More modern, more ergonomic, and visually refined, this 42 mm HydroConquest asserts a stronger wrist presence while maintaining a carefully balanced design. Offered here on a steel bracelet, it enhances its sporty character and versatility, remaining true to the original spirit of the collection.

In this 42 mm format, this version stands out with a more expressive display and a confident presence, ideal for those seeking a watch that is both robust, comfortable, and versatile. A piece designed to accompany every moment of the day with assurance, balancing performance and elegance.

A sport-chic watch for everyday wear

Designed to accompany every moment of the day, this new HydroConquest is part of a modern approach to sports watchmaking, where performance and elegance coexist naturally. Inspired by the aquatic world, it retains the essential attributes of a robust and reliable timepiece, while moving beyond the strict codes of a professional dive watch to better suit contemporary lifestyles.

Water-resistant to 300 meters, equipped with a unidirectional steel rotating bezel and optimal legibility in all conditions, it fully meets the demands of an active environment. Its solid construction and technical features make it a watch ready to handle everyday life as well as more demanding situations.

On the wrist, its 42 mm size asserts a stronger presence while maintaining excellent comfort thanks to refined ergonomics. Paired with its steel bracelet, it enhances its sporty character and robustness while preserving a natural elegance that allows it to fit seamlessly into many contexts. It is equally suited to a workday, a weekend outdoors, travel, or more dynamic activities.

Through this new generation, Longines reaffirms its commitment to offering a contemporary sports watch designed to last and adapt to the varied rhythms of modern life, with reliability, comfort, and versatility.

A deep black dial for a sporty and distinctive look

Completely redesigned for this new generation, the HydroConquest adopts a more contemporary aesthetic, inspired by design codes introduced with the GMT models. In this 42 mm format, the case features smoother and slightly refined lines, asserting a stronger wrist presence while maintaining optimized ergonomics for lasting comfort.

The solid black dial stands out through the depth of its hue and its clean, minimalist reading, subtly changing with the light. Both bold and elegant, it highlights the model’s modernized design, notably through the replacement of traditional numerals with applied hour markers in varied geometric shapes. This evolution brings a clearer and more contemporary time display, enhanced by Super-LumiNova® applied to the markers and hands.

The unidirectional steel rotating bezel extends this strong visual identity, creating a harmonious continuity with the dial. Durable and seamlessly integrated into the design, it also offers precise handling, with an improved tactile feel inherited from the latest technical developments of the collection.

The result is a watch with a strong character, where the black tone adds a distinctive touch while maintaining excellent legibility. A contemporary interpretation of the HydroConquest, designed to combine presence, style, and everyday versatility.
