The OceanX Sharkmaster 600 SMS600-31 is a high quality watch. It pays tribute to diving watches of the present and the past, but does have key OceanX elements. 

Under the hood you will find an automatic, Japanese SII NH35 movement. The glass is 3.8mm thick scratch resistant sapphire glass. The impressive 600 meter water resistance is more than enough for most adventures. The uni-directional 120 clicks bezel has a ceramic insert (which is very scratch resistant) and the characters have lume. All these qualities ensure to the Sharkmaster is able to handle nearly any situation.
