Longines Hydroconquest Quartz 42 Stainless Steel / Blue / Bracelet

About this watch

The Longines HydroConquest L3.769.4.96.6 debuted in 2026 as part of the HydroConquest collection, Longines’ line of contemporary dive watches. The model follows the design direction introduced with the HydroConquest GMT in 2024, which revised the collection’s dial layout and finishing. The round stainless steel case is equipped with a screw-in crown and a unidirectional rotating bezel fitted with an aluminium insert, a configuration used across the quartz-powered HydroConquest models. Water resistance is rated to 30 bar. The watch is fitted with a scratch-resistant sapphire crystal with several layers of anti-reflective coating applied to both sides. The dial is finished in blue with a sandblasted texture. Applied indexes serve as hour markers, reflecting the updated HydroConquest design that no longer features Arabic numerals on the dial. Silvered polished hands indicate the time, while a date display completes the functional layout. Power is provided by the Longines calibre L157, a Swiss quartz movement driving the central hours, minutes, and seconds together with the date indication. The L3.769.4.96.6 is fitted with a stainless steel bracelet secured by a double safety folding clasp.
