Casio G-Shock GA-800 Watches

Representative of the youth series GA in a small building. The watch has a compact display with one digital window, on which all the necessary information is placed. The hands are distinct and pointed, and the hour markers are large and made in a voluminous format, so there will definitely be no problems with the readability of the dial. For ease of use of all functions, it is possible to move the Hand Shift arrows so that they do not block the electronic panel. The GA-800 is sharpened under a stopwatch – it starts with one press of the Start button on the right side of the case and up to 120 laps can be stored in memory. A separate remote button on the front side is responsible for activating the backlight – two LEDs illuminate both the analog and digital zones.
