Longines HydroConquest

The HydroConquest is Longines' modern dive watch. Around since 2007 and fully redesigned for 2026, it delivers the full toolkit: 300 meters of water resistance, a ceramic bezel, a screw-down crown, and an automatic movement with a silicon balance spring and a 72-hour reserve. The latest version slims things into 39 and 42mm cases and adds a Milanese mesh option. This is the daily-wear diver of the range, contemporary and sporty rather than vintage, which is the Legend Diver's job. It gives you a genuine 300-meter Swiss automatic diver, and it's the most accessible way into Longines' dive watches, which is exactly how the brand positions it. That accessibility is the point.
