The Microsoft Band commercial appeals to young, urban professionals who want to make the most of their time.
The commercial's narrator wonders how many moments we miss at work or on our phones, noting with a loud intone that, "we call them moments because they don't last, and we don't know their value until their gone."
The commercial makes clear that time is a finite and precious resource, and the way it's spent contributes significantly to overall happiness. Thus, health, happiness and contentment are wrapped up with efficiency. The core idea in the Microsoft Band commercial is that if people spend their time in truly meaningful ways, they'll be happier and healthier because of it.
