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 colourful 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 vapour 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 CASIO WATCHES 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.

After adjustments are made, the watch can measure running distance more accurately, even without connecting to a smartphone.
Dial design
Employs a combination dial that displays both time and measurements. The dial sports the same texture as the band, and features parts with vapour deposition, hairline, and mirror finishes to deliver visibility and a sense of quality.
Exterior design
The DISP button for switching displays is on the 9 o’clock side so it does not interfere with the wrist, improving operability. The lugs have ventilation parts to provide breathability. The soft urethane band improves fit and has plenty of band holes, allowing for precise length adjustments.
