Certain G-Shock smartwatches — sold under the G-Squad label — include fitness and health analysis features powered by algorithms licensed from Polar, a Finnish company known for heart rate and sports science technology. These features can estimate a wearer's cardiovascular fitness level, score their sleep recovery, and recognize what type of physical activity they are doing, all using data from the watch's built-in sensors. This partnership began with the GBD-H2000 model in 2023.

Details

Starting with the GBD-H2000 (March 2023), G-Shock became the first non-Polar brand licensed to use Polar's algorithm library. Features enabled by this partnership include Running Index (an estimate of VO2max, a measure of cardiovascular fitness), Cardio Load Status (which tracks workout intensity over time), Nightly Recharge (a sleep recovery score), Heart Rate Zones, and activity type recognition (distinguishing between walking, running, cycling, and standing). The DW-H5600 (May 2023) added a Smart Alarm that uses sleep stage analysis to determine the optimal moment to wake the wearer. Neither Casio nor Polar describes these features using the term "AI" in official communications.

Other practices by G-Shock

Creative GenCasio uses generative AI to help design the physical shape and internal structure of certain G-Shock watches. The AI analyzes over 40 years of shock-resistance data to propose structural configurations, which human designers then refine and approve. This began as a one-off project in 2023 and has since expanded to mass-produced consumer models.
