I wear this watch almost every day. If I step out without it, I feel like I'm missing something. The watch is that dependable that I expect it to be correct. If there is a strong enough satellite signal, it will sync overnight. It adjusts for daylight savings, which is awesome. There are two main displays for two different time zones. If you talk to some across the world often, just set it to to that and their time is one button away.
The watch does protrude slightly. If you are wearing long sleeves that fit snug, this will show. For those instances I keep a second, more shiny watch (which is also solar). Never having to worry about battery is pretty awesome.
