Tough Movement: Casio Oceanus and G-Shock Series

Casio's Oceanus and G-Shock series will feature Tough Movement which "fea-tures a high shock resistance and a hand position correction function using LED". During the 55th minute of every hour, Tough Movement automatically receives time calibration signals from six bases located throughout the world; if the individual holes in the gear sprockets don't line up in precisely the exact position as measured by a 16Hz blinking LED and a phototransistor, the watch adjusts accordingly. The first Tough Movement watch, the G-Shock GS-1200, is due out in Japan in September.
