These watches, are they good? Well, the answer is no! They are not simply good, they are outstanding, extremely accurate timepieces. If you want to know exactly, to the second, what time it is, then buy a wave ceptor. Every night it checks itself for accuracy via a signal, and if it is a fraction of a second out it adjusts itself! How good is that! It has all sorts of other features, like telling the time in Japan and such like... but ignore all these, most of us want a watch to be guaranteed accurate, and this does the job 100% My only gripe would be that the instruction leaflet is too small, but that's the only negative! So buy one!
