Ball Engineer Hydrocarbon Nedu

The Ball Engineer Hydrocarbon NEDU is the world’s first diving watch which incorporates a helium release valve into the crown. With this innovation, BALL further improves the watch’s water-resistance, making it a proper tribute to the efforts of the US Navy Experimental Diving Unit (NEDU) in improving diving safety.
