Introduced in 2026, the Longines HydroConquest L3.769.4.06.6 is part of the brand's modern dive watch series, known for its contemporary aesthetic. This model incorporates design elements first seen in the HydroConquest GMT launched in 2024, showcasing an updated appearance with new dial designs and enhanced finishes. Its round case is crafted from stainless steel and features a screw-down crown along with a unidirectional rotating bezel that includes an aluminium insert, a common characteristic among quartz variants of the HydroConquest. With impressive water resistance rated at 30 bar, this timepiece is ready for aquatic adventures.

Protected by a scratch-resistant sapphire crystal enhanced with anti-reflective coatings on both sides, the watch's green dial exhibits a sandblasted finish. The hour markers are represented by applied indexes, moving away from traditional Arabic numerals, and the silver-polished hands indicate the time while a date function rounds out its practical features. The watch is powered by the Longines calibre L157, a Swiss quartz movement that manages the central hours, minutes, and seconds as well as the date. It is completed with a stainless steel bracelet that secures the watch with a double safety folding clasp.
