4.5 stars, nothings perfect! Everything a watch should be. Always accurate to the second, without setting or thinking about it forever with atomic time! Mine syncs great, I live in Georgia, a long way from Denver (location of radio signal), and auto syncs every night! Never needs a battery, with eco-drive, something else I don't have to think about. I love analog watches, but enjoy the digital features of date, timer, chrono, and even alarm. I enjoy and occasionally use the e6b slide rule, (but must take off  watch to really use), but with this type of band, it's off and on in a snap! It is a great size for my 55 year old eyes, and very easy to glance and see time with bright hands and tick marks. Hands glow very well and I can see it at night and in the movies without LED, but digital area of watch does illuminate with LED if required. I didn't find it difficult at all to set, but I enjoy reading the manual and finding out what it will do. Alarm and timer signal is adequate but only chimes for 15 seconds, not really useful to wake by. The crystal is very slightly domed, and I prefer a flat non-reflective crystal, but not really noticeable or a problem. I also like the rotating bezel with the small metal studs at 5 minute intervals, as I like to use this for a handy elapsed time bezel like a scuba watch. I really like the band and quick open/close feature. I had to cut down the band, but it was not a problem, just take your time, as you can't undo a mistake. All in all a great watch. I picked it up for $351, so shop around.
