Edox North Sea Diver's Black Dial Automatic 80118357NGN1 80118 357NG N1 300M Men's Watch The Edox North Sea 1978 is related to the Inverse Moon Landing 320 meters under the frozen North Sea waters of Norway. It was a mission accomplished in 1978 and the new North Sea model recalls the legendary Edox dive watch. It gathered its inspirations from the 1960’s Delfin and the 1970’s Skydiver, capable of straightaway 500 metres dives! The magic of the double O-ring system is present in this Edox as well and that’s why Edox is into an official partnership with the Norwegian North Sea Divers.
