very well preserved comex 5514 non-date submariner with helium, escape valve. Comex logo and issued Rolex were not available to the public and only a handful of examples that were provided to commercial divers have survived over the years.  The dial and hands on this example  are absolutely stunning like new condition with perfect patina. The case was polished in the past however remains thick and even. The bezel insert has faded to a fantastic grey ghost.  The bracelet is a 93150 flip-lock bracelet with 12 links.  The movement is running well and keeping excellent time.  Comes with rolex box and service papers from Rolex stating that this watch was in fact issued to Comex with the appropriate issue number, Hard to understand COMEX rolex without having it on your wrist and this one does not disappoint
