Not all G-Shock watches can boast a GPS module – it’s pretty expensive and “consuming” technology. Only some top G-Shocks support GPS, and they all fall into two categories – for getting accurate time from satellites [few MRGs and other premium lines] and tracking [distance, pace, speed, measurement] during training or hiking [advanced G-SQUADs and GPR-B1000s]. For more details, see our separate selection of TOP G-SHOCK Watches with GPS.
