Take control of your fitness with the charcoal black Polar A300 Fitness and Activity Monitor. This smart fitness tracking watch lets you keep track of your daily physical activity as well as intense workouts, giving you a more complete picture of your health, strength, and endurance. It's waterproof down to 98' and the rechargeable battery lasts for up to four weeks of daily activity tracking, exercise, and sleep.
The A300 motivates you when inactive and lets you set goals for yourself, and lets you keep track of your progress with the Polar Flow smartphone and web app. And when paired with an optional Bluetooth heart rate monitor like the Polar H7, you can gain even more insight into your workouts. It tracks sleep automatically, so there's no need to set the watch to enter a special mode.
At less than two ounces, the A300 is light enough to wear all day, and it stores up to 60 days of data. It can charge via a USB connector hidden in the wristband that extends into your computer's USB port, or with the included charging cable. Additional wristbands in a variety of colors can be purchased separately.
Sync your A300 with the Polar Flow smartphone or web app after you exercise to receive instant feedback.

24-Hour Activity Tracking
The A300's activity tracking feature registers your daily activity at five different intensity levels: resting, sitting, low, medium, and high. You can see how much time you spend at each activity level in the Polar Flow smartphone or web app. It also tracks your steps, calories, and sleep time, and notifies you with a gentle vibration after long periods of inactivity.
When you lie down and your body's movements slow, your A300 begins to track your sleep. It keeps track of the amount of time you spend engaged in restless versus restful sleep, so you can accurately keep track of how much rest you're getting.
