After several weeks of wearing the watch, the only significant change that I have noticed is that I now sleep very soundly. I don't take off my watch even when sleeping. I wasn't expecting any miracles to happen as some may think that the watch will cure major ailments (absolutely not). The Philip Stein watch is a good timepiece. It even looks better than my Omega Seamaster (Planet Ocean). One of the features I like about the watch is that it tells both my time in Los Angeles and the time in the Philippines.
