This G-SHOCK model whose 35mm diameter face and large case give a look of power and strength. Dial rings and raised hour markers also create three-dimensional depth that gives the face plenty of character. These watches are designed and engineered to deliver outstanding shock resistance, are 200m water resistant, and anti-magnetic. The GA-100-1A1ER is beautifully finished in black with pure white hands and a reverse LCD display for a distinctive look.
