Longines unveils the new HydroConquest 2026 generation
Longines HydroConquest 2026 marks the latest evolution of the iconic dive watch collection from Longines.
Originally introduced in 2007, the HydroConquest line has become a cornerstone of sporty watchmaking, combining professional performance with timeless design, now refined for modern users.

Refined proportions
The collection is available in 39 mm and 42 mm stainless steel cases offering balanced proportions, while new lacquered dials in blue, black and green alongside a distinctive frosted blue variant add depth and visual sophistication.

Ceramic bezel of the Longines HydroConquest 2026
The new models feature five ceramic bezel options including black, blue, slate grey, green and luminous blue, paired with an improved unidirectional rotating system and a Super-LumiNova® marker at zero for optimal visibility.

Movement
At the heart of the Longines HydroConquest 2026 is the exclusive L888.5 automatic calibre.
This movement delivers high precision and enhanced resistance to magnetic fields thanks to its silicon balance spring, exceeding ISO 764 standards. It also offers a power reserve of up to 72 hours.
Innovative bracelets
The collection includes stainless steel bracelets with H-shaped links and a micro-adjustment clasp, as well as a new Milanese mesh option that combines classic elegance with modern comfort and breathability.


A spirit of adventure
With water resistance up to 300 meters, a screw-down crown and robust construction, the HydroConquest remains a true diver’s watch while evolving into a versatile timepiece suited for both adventure and refined settings.
