I very much enjoy having a watch that updates time with the government time standard.  While I have only had the watch a week, it has been flawless in maintaining the time accurately.  I have worn it the whole time and have received the update signal without removing the watch and placing it near a window.  I highly recommend watching the YouTube video on adjusting the watchband length.  I had to remove several links to get a proper fit.  After watching the YouTube video mentioned elsewhere in these reviews, dealing with the watchband was fairly straight forward and was accomplished with an ice pick and a needle-nosed pliers.  If the entire watch case were stainless instead of partly plastic, I would have given another star.
