Casio G-Shock GD-120 Watches

About GD-120 in Short. Popular G-Shocks with digital time display and a fairly large body. The dial has only the main electronic display and 3 round windows to indicate all the functions of the watch. Due to its brutal design and shock-resistant properties, the GD-120 is in demand in the military environment, although this is not the official positioning of the model. In addition to a separate world time mode, the watch has a convenient switch between 4 time zones – for those who often travel to different cities of the world. The functionality is very worthy for its price – a stopwatch, a timer, an alarm clock, a flashing signal and an auto calendar. In addition, a powerful Super Illuminator is provided to illuminate the dial. The 7-year battery will make you forget to replace it for a long time.
