The OceanX Sharkmaster 1000 Titanium SMTi1011 Limited Edition 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 SII NH35 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). All these qualities ensure to the Sharkmaster is able to handle nearly any situation. However the biggest thing to make this an incredibly comfortable watch is that both the case and bracelet are made from Grade 5 titanium. Grade 5 matters as well, as this has a higher strength to weight ratio than grade 2 and it's more scratch resistant. However it's much more complicated to machine, hence most brands opt for grade 2. 

This limited edition of just 50 pieces worldwide also features a new, slimmer case and updated clasp.
