This is another one of the Iconic Rolex Submariner range. This model is the 14060 2 liner, which was produced up to around 2008 then they did a Cosc version knows as the 4 liner up to 2011 then Rolex phased it out for the upgraded ceramic version.
This is a non date sub version and is a true classic dating back years, this version was not Cosc standard in time keeping as the other Rolex date version was, neither the less a great watch with smooth lines as not everyone seems link the infamous Rolex cyclops.
