NOWATCH is a beautiful piece of wearable jewellery capable of measuring a range of different vital signs and analyses. Being a screen-less device, the product comes with an app to monitor data and foster habit change. Whilst most other wearable focus on optimisation and performance for fitness, NOWATCH focuses on helping people restore balance in daily life.
