Longines HydroConquest automatic ice-blue dial milanese 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 refinement.

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. Paired here with a Milanese mesh bracelet, it adopts an even more elegant and contemporary look, reinforcing its sport-chic positioning.

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 visible, comfortable and versatile. True to the collection’s DNA, it accompanies every moment of the day with confidence, balancing dynamism and elegance.

A sports watch with refined character

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 meets the demands of an active environment. Yet it is in its ability to go beyond this framework that it truly stands out. More than a technical instrument, this HydroConquest is designed as an everyday watch, capable of integrating seamlessly into a wide variety of situations.

On the wrist, its 42 mm case asserts a stronger presence while maintaining excellent comfort thanks to refined ergonomics. Paired with its Milanese mesh bracelet, it gains in fluidity and elegance, offering a particularly well-balanced combination of visual strength and refinement. It accompanies a working day just as naturally as a weekend outdoors, a trip or a more formal occasion.

Through this new generation, Longines reaffirms its ambition to offer a contemporary sports watch, designed not for a single use, but to adapt to the rhythms and environments of modern life, with confident presence and refined elegance.

A luminous ice-blue dial structured by a black bezel

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 sunburst ice-blue dial stands out with its subtle texture and shifting reflections, capturing the light with finesse. More expressive and resolutely contemporary, it brings a new visual dimension to the collection while highlighting the dial’s modernization, marked by applied indexes with varied geometric shapes. This streamlined construction enhances legibility, supported by the Super-LumiNova® treatment on the indexes and hands.

The black ceramic unidirectional rotating bezel structures the overall design through a sharp and elegant contrast. It highlights the brightness of the dial while providing a more defined visual reading, reinforcing the watch’s contemporary character. Scratch-resistant and perfectly integrated, it also offers precise handling, with an enhanced tactile feel resulting from the latest technical developments of the collection.

The result is a watch with a luminous and assertive aesthetic, where the freshness of ice blue interacts with the depth of black. A combination that fully embodies the evolution of the HydroConquest: a contemporary sports watch designed to combine presence, legibility and distinction in everyday life.

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.

A Milanese bracelet with contemporary refinement

Offered for the first time in the HydroConquest collection, this version with a stainless steel Milanese mesh bracelet introduces a more elegant and sophisticated dimension. Inspired by historical bracelets, this type of construction is distinguished by its fine and regular weaving, offering a unique visual texture and a particularly refined look on the wrist.

Beyond its aesthetics, the Milanese bracelet stands out for its comfort. Flexible and lightweight, it naturally follows the shape of the wrist, providing a fluid feel and excellent breathability for everyday wear. This construction also allows for more precise adjustment, ideal for extended wear in all situations.

Its slightly tapered design towards the clasp enhances the overall balance of the watch while adding a contemporary touch. It is fitted with a double-security folding clasp, incorporating a practical micro-adjustment system, allowing easy adjustment for optimal comfort.

Elegant, comfortable and resolutely modern, this Milanese bracelet perfectly embodies the evolution of the HydroConquest. It transforms the sports watch into a more urban and refined piece, capable of adapting effortlessly to all styles and moments of the day.
