I doubt so. I did intense testing as I received my Fenix and the values were absolute random and didn´t fit my real sleep cycles. Since a few months I didn´t bother anymore and leave it in my bathroom in the evening and it still gives random values. I first thought it must be defective, but a few friends of mine did the same with theirs and the values also don´t fit the time of removal. In my opinion it is not even a gadget and more of a fraud...If the fenix 3 hr watch has any merit to its sleep cycle monitor.
