New LONGINES HydroConquest: Adventure Meets Elegance

Redesigned for the modern explorer

For 2026, Longines reimagines the HydroConquest with 39 mm and 42 mm automatic models, combining modern proportions with everyday wearability. Dials in blue, black, green, and frosted-blue feature Super-LumiNova® indices, framed by ceramic bezels in multiple colours. An upgraded unidirectional bezel, screw-in crown, and 300 m water resistance ensure performance to match the refined design.

Power beneath the surface

Powered by the Longines calibre L888.5, each watch delivers high precision, strong magnetic resistance, and a 72-hour power reserve. A screw-down case back with a planisphere engraving nods to the brand’s GMT models.

The collection continues its explorer heritage with stainless-steel bracelets featuring H-shaped links and a double-folding clasp with micro-adjustment for a tailored fit.

A first for HydroConquest

Brushed stainless-steel Milanese mesh bracelets with polished edges elevate the HydroConquest’s refined, sporty look. Their tapered, breathable design and micro-adjustment clasp offer comfort and versatility, reflecting the collection’s balance of precision and effortless elegance.

Two exclusive 39 mm and 42 mm HydroConquest models feature frosted-blue dials with a dynamic sunray texture that shifts with the light. Available only through Longines boutiques and online, they pair marine-inspired tones with dark-blue ceramic bezels and stainless-steel bracelets, offering a distinctive take on the collection’s signature sporty elegance.

Henry Cavill introduces the next-generation HydroConquest

The new HydroConquest is embodied by Henry Cavill, Longines Ambassador of Elegance since 2024. Filmed on Tenerife’s volcanic shores, the campaign captures Cavill navigating land and sea, reflecting the watch’s versatile, adventurous spirit.

“This watch brings with it a sense of lightness and dignity. It evokes thoughts of spring and summer shores, docksides and with them the promise of discovery; evocative of the classic elegance from Longines.”
Henry Cavill

The HydroConquest traces its roots to the 1954 Conquest, Longines’ first trademarked line, known as “the everyday watch” for its versatile performance. Launched in 2007, HydroConquest added 300 m water resistance, creating a sporty yet refined line. Subsequent updates, including 2018’s refined sizes and ceramic bezels and 2023’s redesign with new colours and the first GMT, have evolved the collection while maintaining its core identity. The 2026 generation continues this legacy, blending heritage with modern innovation for a versatile, contemporary icon.
