The Mako II has a larger case size (46mm), an improved and beefier bracelet, a larger uni-directional bezel with easier to read numbers, and larger hour markers that are treated with luminous material. The second hand is now moon-shaped and luminous to help let you know your watch is operating under water and in the dark. Inside is the "bullet-proof" Orient 21-jewel automatic (self-winding) movement. Features a screw-down crown and case back.
