This watch was a replacement for the fossil smart watch that broke before it. I went with the hybrid because it was less complicated and I thought it might last longer than a year. I like the style and the long battery life compared to the gen 4. With that long battery life, I was excited to be able to wear it for consecutive days and nights because I love getting my sleep data. However, when I leave it on for more than a couple days it starts to burn my arm. I have to wear it tight enough to pick up my pulse but then after a day my wrist is red, irritated, and burnt under the sensors and watch band.
