QUADTEC is the world's first digital timepiece which displays quarterly time periods moving around every hour centered in the watch face. You can choose any of three types of QUADTEC time sequences to suit the occasion or your preference. The first and second quarters can be displayed on the right as elapsed minutes past the current hour, followed by the third and fourth quarters shown on the left as minutes approaching the next hour ("EF" sequence). Or, all four quarter hours can be displayed as elapsed quarterly segments of past minutes traveling around the current hour ("ES" sequence). A third choice is to display the four quarters as elapsed unified minutes which remain stationary ("EU" sequence), in a format resembling the EF and ES displays. These options are always available during real time by simply pressing a SELECT button. QUADTEC sounds a pleasant alarm melody which can be easily set to provide a wake up call, or announce any other time you wish to hear. All setting functions and an electroluminescent light for night viewing are controlled by labeled buttons which are ergonomically designed for easy use. Comes with a stainless steel bracelet, black leather and orange rubber band.
