Baselworld 2010: Rolex has completed it’s planned upgrade of the iconic Submariner sports watch. Over the past two years, the Rolex Submariner has been reborn with a new “Cerachrome” ceramic bezel, a new dial featuring larger luminescent indices and hands, and a larger 40mm reconfigured case with wider lugs. The watch also features a glidelock clasp for easy adjustment of the bracelet. The new Submariner is water resistant to 300 meters. These subtle improvements only add to what has been considered the ultimate sports watch. The new stainless steel model Submariner will now be offered in a optional green bezel and dial to go along with the classic black and black Submariner (see photo).
