G-Shock's thinnest digital watch to date; the GDB500-1 features a matte black design with updated proportions. It connects to the G-Shock App via Bluetooth - so you can easily adjust alarms, log data, and locate your smartphone with a chime. Designed with the brand's all-new Glass fiber resin and 200 meters of water-resistance, the ultra-functional silhouette comes finished with a step counter, Super Illuminator lighting, and timing functions to suit your daily routine.
