WORLD FIRST: A HELIUM RELEASE VALVE BUILT INTO THE CROWN.
The Engineer Hydrocarbon NEDU represents major technological innovation in the design of diving watches. Dedicated to the Navy Experimental Diving Unit (NEDU) – a United States Navy unit responsible for rolling out operational diving and decompression rules for the US Armed Forces – the NEDU timepiece is a tool watch of the highest order, featuring extraordinary water resistance and technology strong enough for military missions.
The automatic BALL RR1402-C movement is a chronograph caliber that measures and indicates elapsed time up to 12 hours. Its COSC certified precision is protected by anti-shock and anti-magnetic technology. The self-winding movement is securely housed inside a robust 42mm case with a thickness of 17.3mm, while the case back features a diver motif echoing NEDU’s official emblem.
