Citizen has consciously designed activity tracking software that prioritizes battery life for your watch. Many options are available to track everything from steps to a full workout, but the Citizen Gen 2 watch Activity mode, started directly from the Gen 2 Wellness watch app, maximizes battery life. You can also see your full activity tracking data directly in your YouQ software on your phone. We have optimized the activity mode to allow you to use GPS during an hour-long workout, including heart rate, steps, calories and more, and still give you plenty of charge to last throughout the day before you return to your charging station.
