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 –. Built from chromed pure black ceramic, the uni-directional rotating bezel is exceptionally resistant to corrosion, scratches and ultraviolet rays. On the aviator-inspired dial, revolutionary micro gas tubes shine at each hour index and on the main hands for easy readability. Along with 600 meter water resistance, the NEDU features a world first in watchmaking: the automatic helium release valve is directly incorporated into the crown. 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.
I found Iguana really friendly, helpful and efficient to both buy the pen and when I had a query - very quick to respond. The pen is gorgeous and I’m now using it every day.
