Longines HydroConquest quartz blue dial steel bracelet 42 mm

The story

Since its launch in 2007, the HydroConquest collection has embodied a distinctive vision of the Longines 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 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 maintaining a strong urban vocation, it has established itself for nearly two decades as a benchmark among contemporary sports watches, combining robustness, legibility, and uncompromising style.

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 balanced profile. Offered here on a stainless-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 a more expressive presence and a confident wrist presence, ideal for those seeking a watch that is both robust, comfortable, and versatile. A timepiece designed to accompany every moment of the day with assurance, blending performance and elegance.

A sport-chic watch for everyday wear

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

Water-resistant up to 300 meters, equipped with a unidirectional rotating stainless-steel 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 ready to face both everyday life and more demanding situations.

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

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 green dial for a distinctive sporty style

Fully redesigned for this new generation, the HydroConquest adopts a more contemporary aesthetic inspired by the design codes introduced with 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 green dial stands out through the sobriety of its tone and its clean visual expression, subtly shifting with the light. Both bold and elegant, it highlights the modernized design, notably through the removal of traditional numerals in favor of applied geometric hour markers. This evolution offers a clearer and more contemporary time display, enhanced by Super-LumiNova® treatment on the indexes and hands.

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

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