The good: Good quality. Keeps accurate time. The not so good: The not so good is not a problem with the watch but a problem with adjusting the metal band. And that is not the band's fault. That's my fault. To adjust the band so it fits the wrist one must take out links in the band. A tool comes with the watch to aid link removal. I just could not do it. So I replaced this band with another metal band that has a quick adjust magnetic closure.
