G-Shock • GBA900CB-7A • Men's Watch

Presenting the cool and breezy GBA-900, from the tough, sports-oriented G-SQUAD line.

Inspired by the invigorating feel of a workout by the sea, the deep cobalt blue and vibrant blue green are firsts for a Casio dial. The colorful dial is set against basic black or pure white in one of two bold, eye-catching designs. Hour and minute hands are finished in silvery vapor deposition to add shimmery style and enhance readability. 

As much function as style, these G-SQUAD GBA-900 watches deliver all you need for the ultimate workout. Just pair with a smartphone to track runs, access the watch’s acceleration sensor and use your smartphone GPS to adjust distances. Adjust once on the smartphone, and track distances traveled using just the watch from then on. Automatically track pace and running times for set distances with auto-lap readings. Connect to the G-SHOCK MOVE smartphone app and easily check activity history and life logs with step count and calories burned on your watch.

Bring your all to daily workouts with a G-SHOCK that is up for whatever you take on.
