A watch is a handcuff, a manacle. It's like a sign that you're a cog in the wheel of society. That's why I use a smart watch that can measure my HR in seconds. This is because it is the only way I can measure the intensity of my workout when I'm doing strength training or dancing. Being able to log my body's condition means I can know my rhythm, and I think body sensing is something that only a smartwatch can do.
