Longines HydroConquest 41mm Ref. L3.781.4.56.6

About this product

The HydroConquest is Longines' dive watch, and this is the version that keeps everything monochrome: a black ceramic bezel over a sunray black dial, so the only contrast on the watch comes from the polished steel case and the luminous markers. At 41mm it sits in the middle of the range, on a 21mm lug width that carries the steel bracelet and its double safety folding clasp. Inside is the calibre L888.5, a self-winding movement running at 25,200 vibrations per hour with a power reserve of up to 72 hours — three days off the wrist, which is the practical difference between this generation and the ones before it. The case is rated to 300 metres, with a screw-in crown, a screw-down back and a unidirectional rotating bezel. Applied Arabic numerals at twelve, nine and six carry Swiss Super-LumiNova®.

This watch comes with the manufacturer's warranty card, backed up by our own Alan Furman & Co warranty.
