Break through every limit! Upgrade your workout gear with the sports-oriented G-SQUAD line of G-SHOCK watches.

The GBD-100LM features glow-in-the-dark resin where the bezel and the band meet, to shine with assurance in unlit spaces. With a luminescent camouflage pattern band inspired by urban nightscapes, there’s no mistaking this bold design, day or night.

As much function as style, this G-SQUAD delivers 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. Auto-lap readings automatically track pace and running times for set distances. 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.
