Two-piece Bezel Construction and a remarkably thin 11.1mm case highlight the OCWM800. A bezel constructed of two pieces, with lower piece seemingly tucked under the upper piece, adds visual depth and produces a face design that is both elegant and sporty. Through miniaturization and precise layout of parts, a slim-styling of the case and bezel is achieved. Multi-function, radio-controlled, solar-powered chronograph with countdown timer.
