I was a bit confused whether to buy a apple watch or not as I had never used one. I bought it anyway and I am happy that it was worth every penny. Sleep tracking is so good, plus it has the crash mode feature available now. I literally have to touch my phone less now as most of my work is done through watch. The ECG and Blood oxygen just add another charm to the watch. Overall a watch which you can use for like 10 years and it'll be still good.
