I've loved Withings hybrid watches, which pack all the health tech you need into an analog watch body, for over a decade. The ScanWatch Nova integrates the hardware of the ScanWatch 2 into the body of a dive watch and looks much more luxurious than it actually costs. And, of course, it has all the fancy health and fitness equipment a loved adult might be interested in purchasing.
Buried inside that case is a built-in ECG, heart rate, and oximeter, as well as a temperature sensor. You'll get sleep monitoring, automatic activity tracking, and access to the best-in-class Withings Health app. But for me, the most attractive feature is the 30-day battery life, which will give you 29 and a half more days of battery life on a single charge than the comparable Apple Watch.
Actually, the most attractive feature is the analog subdial that will track your set step count based on the goal that suits you best. If you're running late and want to make sure you've completed all 10,000 steps, that information is there. Therefore, it is useful, practical, stylish and will outperform many other smartwatches on the market. Any questions? — CC
