The Nowatch was shown at CES 2022, and now it is finally going on sale. It looks like a watch, but it can't tell the time. Instead, it's packed with sensors to track your heart rate, sleep, steps, and—most important—your sweat glands. With this data, and thanks to a collaboration with the health-tech company Philips, the wearable monitors your stress level and can tell when it's about to get worse. By predicting it early, the Nowatch's app can suggest actions to help you de-stress. (It uses the same chip as the Oura Ring.) Press the button to log a “moment” and the app will show a visual indicator of how you're feeling based on the data. You can swap out the tops, each of which is a different type of gemstone. (The company says the stones are all sustainably sourced.) The base wearable costs 299 euros ($318), and the stones start at 25 euros ($27) each. —Julian Chokkattu
