What sets this model apart
- Octagonal case - an eight-sided shape with pronounced edges, a noticeable design detail that immediately distinguishes the GA-2100-1A from classic round G-SHOCK models.
- Ana-Digi dial - two analog hands (hour and minute) in silver color plus a digital display in the lower part: time, date, alarm indicators, DST and silent mode.
- Small subdial to the left of center - an additional analog element characteristic of this model.
- Electroluminescent backlight - read the time in darkness with a single press of the LIGHT button.
- Water resistance 20 BAR - suitable for swimming, diving and other water activities.
- Quartz movement - stable accuracy without the need to adjust the hands daily.
- Case diameter 45 mm, weight 51 g - noticeable on the wrist, but not burdensome during extended wear.
- Four side buttons in silver color for controlling functions: ADJUST, LIGHT, MODE, START.
