• NOTABLE COMMENTS: Unbelievable quality and technology.  Seiko Engineers have thought of everything.   All black casing is not just beacuse it looks great (and it does look great).  It is quite dark in the deepsea, so casing is simulating the deep sea environment for every day use.  By adjusting divers vision and brain during everyday use, it puts less stress for the diver when watch is actually used in deepsea environment, easily recognizing time.

Utilized special L shped gasket to fit the sapphire crystal (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.

• CW RECOMMENDED OPTION: ZULU 22mm strap , ZULU BZ-4 22mm strap goes extremely well with this watch!
