    Detailed Test Results

    Overall this model was very easy to use, somewhat accurate for counting steps, and good at measuring heart-rate accuracy. With recent version smartphones, our experts found it very easy to pair, very easy to interact with, and very easy to connect to charger. The watch face was very good in our scratch resistance hardness test. It passed our water immersion test at 164 feet for 10 minutes.
