To clarify, the Tumi is just the Frontier with a Tumi band and available Tumi watch face - no difference in performance or function. To answer your question, yes, they track your sleep. I haven't analyzed the overall effectiveness, but it's pretty smart and gets my "going to bed" and "wake up" times almost exactly. I don't have to do anything.
Sorry, there was a problem. Please try again later.Yes, it does monitor your sleep, light, restless, etc. It also has a graph. It has all kinds of faces for the watch you can download. Very cool watch.
