Right now the Oceanographic 4000 (4000m) watch comes in two limited edition variants. First is the titanium model that is limited to 1000 pieces, and then there is the all-black carbon fiber model that is limited to 500 pieces. The King Power style case is 48mm wide and really thick - still comfy though to be quite honest given the light weight. It has a sapphire crystal that is 6.5mm thick, a helium escape valve, and 4000 meters of water resistance. According to some additional information, another test seems to suggest that the watch is water resistant to 5000 meters. Which is it? Doesn't matter to be honest - you'd be dead long before reaching either of those depths.
Still, the carbon fiber model speaks to me a lot more. I am actually not a big fan of all those black on black watches. Mr. Biver calls the look "visible invisibility." The titanium and green model looks a bit like a toy to me. I mean, it is toy. Maybe a serious toy, but still a toy. This is another watch that I call "Hollywood movie prop." Pick your fav sci-fi or action movie and I bet this watch will look appropriate on some character. The carbon fiber one is a bit more mysterious and sinister. It also has the benefit of being the only carbon fiber cases dive timepiece that I know of - and that is pretty cool. I am pretty hot on the idea of carbon fiber cases. I was very skeptical about them at first, but brands like Hublot have convinced me that they are worthy. In addition to being light and having a smooth feel to them, they are really tough and naturally absorb shock.
