  • BATTERY LIFE: approx. 5 years long life battery w/ low battery indication.
  • NOTABLE COMMENTS: Unbelievable value.  Very functional Professional Diver's watch which will withstand mixed-gas use scuba diving at reasonalble cost.  Tricle down technology from world famous SEIKO diver's watches supported by professional diver's all around the world.  Smaller brother of SBBN013 at fraction of the cost.  Very nice looking watch to wear around for everyday use.  Will get attention!  
  • Utilized special L shped gasket in it's screwback case (first in the world) to prevent small helim gas particles (used in helium/oxygen tank) from entering the watch case during diving.  This elimited the need for helium escape valve.

  • Luminous is one of the brightest we have come across.  Operation of the screw down crown is the smoothest we know.  There are no sharp point or edges in any part of the watch case, so that you will not hurt yourself or damge your wetsuit while diving.
