Longines HydroConquest automatic 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: that of 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 watchmaking tradition where every detail is designed to accompany everyday life with precision and exacting standards.

With the HydroConquest, this ambition takes on a new dimension. Inspired by the aquatic world while maintaining a strong urban vocation, it has established itself over nearly two decades as a benchmark among contemporary sports watches, 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 presence on the wrist while maintaining a well-balanced profile. Offered here on a steel bracelet, it reinforces its sporty character and versatility, staying true to the original spirit of the collection.

In this 42 mm format, this version stands out with more expressive readability and a stronger 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 confidence, balancing performance and elegance.

A sport-chic watch for everyday life

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 professional dive watches to better suit contemporary lifestyles.

Water-resistant to 300 meters, equipped with a unidirectional rotating bezel and offering 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 both everyday life and more demanding situations.

On the wrist, its 42 mm case asserts a stronger presence while maintaining excellent comfort thanks to refined ergonomics. Paired with its steel bracelet, it reinforces its sporty character and robustness, while maintaining a natural elegance that allows it to adapt to a wide range of contexts. It accompanies a working day just as naturally as a weekend outdoors, a trip or more dynamic activities.

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

An intense black dial for a modern and assertive aesthetic

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

The lacquered black dial stands out for its depth and intensity. Sleek and perfectly legible, it highlights the modernization of the design, notably through the removal of traditional numerals in favor of applied indexes with varied geometric shapes. This evolution provides a cleaner and more contemporary time display, further enhanced by the Super-LumiNova® treatment on the indexes and hands.

The black ceramic unidirectional rotating bezel extends this approach by reinforcing the visual cohesion of the watch. Scratch-resistant and perfectly integrated into the design, it also offers precise handling, with an enhanced tactile feel inherited from the latest technical developments of the collection.

The result is a watch with a strong and functional aesthetic, where the sobriety of black highlights both legibility and robustness. A contemporary interpretation of the HydroConquest, designed to combine performance, clarity and everyday versatility.

Movement and performance

At the heart of this HydroConquest beats the Longines L888.5 automatic calibre, an exclusive movement renowned for its reliability and performance suited to everyday demands. Equipped with a silicon balance spring, it offers increased resistance to magnetic fields, a key advantage in a modern environment where sources of interference are numerous.

This movement also stands out for its comfortable power reserve of up to 72 hours, allowing the watch to maintain autonomy over several days without being worn. Stable and precise, it accompanies every moment with consistency, whether in daily use or during more demanding activities.

Designed to last, the L888.5 calibre perfectly illustrates Longines’ approach: offering accessible, reliable and technically accomplished watchmaking, without compromising performance or user experience.

Steel bracelet with micro-adjustment

This HydroConquest is fitted with a stainless steel bracelet featuring H-shaped links, directly inspired by the GMT models of the collection. This design, both structured and contemporary, reinforces the sporty character of the watch while maintaining a discreet elegance perfectly suited to everyday wear.

Carefully integrated into the case, this bracelet offers harmonious visual continuity and a natural fit on the wrist. Its construction ensures both robustness and comfort, allowing extended wear without constraint, whatever the conditions.

It is equipped with a double-security folding clasp, incorporating a highly practical micro-adjustment system. This allows the bracelet size to be easily adapted for optimal comfort throughout the day, particularly in response to changes in temperature or activity.

Reliable, comfortable and highly versatile, this steel bracelet highlights the identity of this HydroConquest: a contemporary sports watch designed to accompany every moment with ease and elegance.
