Polar's new A300 activity tracker can measure the steps you take, distance you travel, calories you burn and your sleep at night. It will also vibrate to wake you up in the morning and alert you to get up and move.
Bluetooth is on board to sync with the Polar Flow mobile app on your Android or iOS device. The watch supports wireless chest-based heart-rate monitors and it's waterproof so you can wear it while swimming or in the shower.
The strap on the watch is interchangeable and the full device pops right out.
What's interesting is the method the A300 uses to charge. After removing the strap you will notice a small USB plug that connect directly to your PC.
Additional straps in white, black, pink, blue, gray and yellow can be had for $25 (£16 or AU$30 converted).
The watch itself will be available in the US in February for $140. UK and Australian prices were not announced, but the US price converts to around £90 or AU$175, but expect final prices to differ. The watch can also be bundled with a heart-rate monitor for $180 (£120, AU$220 converted).
