About G-7900 in Short. Massive G-Shock-s for those with large hands. Four bezel screws and stepped strap inserts create a powerful effect on the case. The digital display is divided into sections – each function has its own zone. The dial and module are designed for trouble-free operation in severe frost conditions – down to -20 ° C. For beginner sailors and fishermen, the watch provides a display of data on the phases of the moon and a tide / tide sensor. Two separate stopwatches [1000 hours each] allow different time periods to be counted simultaneously and the yacht timer function will beep every minute during the regatta. An advanced alarm clock with the ability to configure 5 signals will not let you miss several important events at once. Finding out the time at night is not a problem – fluorescent illumination does an excellent job of illuminating the dial.
