I first bought an open box and found the analog hands would not install. The clock worked differently, but for that. I was afraid the watch would look ridiculous on me, but when I tried it on I actually found that it wears a lot less than you might think. It's very convenient and very easy. So I sent the defective one back and ordered a new one. That's great. Came exactly to 5 seconds of an atomic clock. All I had to do was reset my home time zone and it has kept perfect time ever since. Now I might have to get the GWG1000 at some point. If the GG had a multi-zone and a solar panel, I think it would be the perfect watch. Here is a wrist snapshot and size comparison to the 5610.
