G-Shock GBA-800-1AER

You need gear that keeps up with your pace, not something that holds you back.

Whether you are on shift or training, your watch should support your performance without distraction. The G-SHOCK GBA-800 is built for exactly that.

Built for movement
Shock resistant construction protects against daily knocks and impact, while the compact, lightweight design stays comfortable during long shifts or training sessions. The secure fit and flexible band keep it in place, even during high-intensity movement.

Track your activity
