The newest model from the highly regarded Orient M-force collection comes in the form of the Orient M-Force "Air Diver". With its rugged design and essential functions, the M-Force "Air Diver" is worthy of being a part of the rich M-Force heritage. The yellow dial is very easy to read; it is complete with luminous hour markers and hands. The offset power reserve indicator hand also has luminescent material as well. The stainless steel bezel maintains precision at 120 clicks and is very legible due to the stark black and white contrast. The case measures at 46mm wide and 13.3mm thick. This is due in part to the implementation of Orient's own special structure which has earned this watch ISO certification in three areas: water resistance (200m), shock resistance and anti-magnetism. The structure increases the shock resistance of the case in order to continually keep accurate time. The movement is self-winding, hand winding and hacking (wherein the seconds hand will stop when the crown is put in its second position). The M-Force "Air Diver" comes conveniently mounted with an Orient branded urethane strap for flexibility and comfort. The watch comes in an "M-Force" Box with instruction manual.
