Longines HydroConquest quartz watch, black dial, steel bracelet, red gold 5N PVD, 42 mm.

The Story Behind It

Since its launch in 2007, the HydroConquest collection has embodied Longines’ unique vision of the sports watch: a timepiece capable of combining technical performance with natural elegance. True to the heritage of the Conquest line, the first collection registered by the brand in 1954, it continues a watchmaking tradition in which every detail is designed to accompany everyday 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 appeal, it has established itself over nearly two decades as a benchmark among contemporary sports watches, seamlessly combining robustness, legibility, and style.

In 2026, Longines unveils a completely reimagined generation of its iconic model. More modern, more ergonomic, and visually streamlined, this 42 mm HydroConquest delivers a stronger wrist presence while maintaining a perfectly balanced design. Presented here in an elegant two-tone configuration combining stainless steel with 5N red PVD finishes, it adds an extra touch of refinement while preserving the collection’s sporting DNA.

In its 42 mm format, this version stands out with its expressive dial and confident presence, making it ideal for those seeking a watch that is robust, comfortable, and versatile. A timepiece designed to accompany every moment of the day with confidence, balancing performance and elegance.

A Sport-Chic Watch for Everyday Wear

Designed to accompany every moment of the day, this new HydroConquest reflects 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 diving watch to better suit contemporary lifestyles.

Water-resistant to 300 meters, equipped with a unidirectional rotating bezel, and offering excellent readability in all conditions, it fully meets the demands of an active environment. Its solid construction and technical specifications make it ready to tackle both everyday challenges and more demanding situations.

On the wrist, its 42 mm case delivers a more assertive presence while maintaining outstanding comfort thanks to its refined ergonomics. Paired with its two-tone bracelet, it enhances its distinctive character and versatility while retaining a natural elegance that allows it to adapt effortlessly to a wide variety of settings. It is equally at home during a workday, an outdoor weekend, a journey, or a more dynamic activity.

Through this new generation, Longines once again demonstrates its commitment to creating contemporary sports watches designed to last and adapt to the varied rhythms of modern life, offering reliability, comfort, and versatility.

A Deep Black Dial Enhanced by 5N red PVD Finishes

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

The sunray black dial stands out through the depth of its color and its changing reflections depending on the light. Both sporty and refined, it highlights the modernization of the design, notably through the replacement of traditional numerals with applied indexes featuring a variety of geometric shapes. This evolution delivers a cleaner and more contemporary reading of time, further enhanced by the Super-LumiNova® coating applied to the hands and indexes.

The black unidirectional rotating bezel integrates harmoniously with the overall design and is distinguished by its 5N red PVD-coated outer ring, whose warm tone echoes the bracelet’s central links as well as the matching screw-down crown. This subtle interplay of contrasts gives the watch a more sophisticated visual identity while preserving its sporty character.

The result is a timepiece with a strong personality, where the combination of deep black tones and 5N red PVD accents creates an elegant balance between modernity and tradition. A contemporary interpretation of the HydroConquest, designed to combine presence, style, and versatility in everyday life.

Movement and Performance

At the heart of this HydroConquest beats the Longines L157 quartz calibre, a movement renowned for its reliability, precision, and ease of use. Designed to provide consistent timekeeping without the need for regular maintenance, it reflects a modern and practical approach to watchmaking.

Two-Tone Steel Bracelet

This HydroConquest is fitted with a stainless-steel bracelet featuring H-shaped links, directly inspired by the GMT models within the collection. The 5N red PVD-coated central links add an extra touch of refinement and reinforce the distinctive two-tone identity of this version. Combined with the crown and bezel edge finished in the same coating, they create a cohesive and particularly elegant overall aesthetic.

Carefully integrated into the case, the bracelet provides seamless visual continuity and a natural fit on the wrist. Its construction ensures both durability and comfort, allowing for extended wear in any environment. It is equipped with a double-security folding clasp.

Reliable, comfortable, and remarkably versatile, this two-tone bracelet perfectly complements the identity of this HydroConquest: a contemporary sports watch designed to accompany every moment with ease, distinction, and elegance.
