The OceanX Sharkmaster 1000 M9 SMS1032M9 is a high quality diving 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 Premium-grade Miyota 9015 movement. The glass is 4.1mm thick scratch resistant sapphire glass. The impressive 1000 meter water resistance of this watch is possible due to the helium valve, that you can see on the side of the case. 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. The M9 series is noticeably more slim than the normal Sharkmaster 1000 series, 14.85mm compared to 17.1mm, ensuring a more comfortable fit on your wrist!
