Longines was founded in Saint-Imier, Switzerland in 1832, making it one of the oldest watch brands in continuous production in the world. As part of the Swatch Group, the brand has consistently offered Swiss-made quality and in-house movement development at a price point that remains accessible to a wide audience. The HydroConquest is Longines' dedicated sports diver line — a collection built around genuine 300-metre water resistance, serious movement specifications and a clean, versatile aesthetic that works equally well in and out of the water.

The Longines Hydroconquest reference L3.788.4.96.6 is a 42 mm stainless steel automatic diver's watch, 11.7 mm in thickness, with a polished and brushed case and screw-down caseback. The blue lacquered polished dial carries applied indices and silvered hands with Swiss Super-LumiNova, with a date window at three o'clock. At its heart beats the Longines Calibre L888, a self-winding movement with a monocrystalline silicon balance spring running at 25,200 vph and delivering a 72-hour power reserve — serious specifications at this price point. The sapphire crystal carries multiple layers of anti-reflective coating on both sides. The unidirectional rotating bezel features a blue ceramic insert with a graduated diving scale. Water resistance is rated to 300 metres. The watch is fitted on a stainless steel bracelet with a double security folding clasp and micro-adjustment system.

This Longines HydroConquest is in mint condition and comes as a full set with factory warranty until 2031!
