POSITIVES:
1.  This is a cool looking watch.  If you want a watch that looks good whether you're backpacking or on a dress-up dinner date, this will do.
2.  The atomic function works well.  I live near cloudy Seattle on a side of a mountain where cell phone strength is very weak and it takes 5+ minutes for GPS's to triangulate where I am, but this watch always was able to get the time at night.
3.  The display is great, crystal clear, easy to read the time with just a glance.
4.  The band seemed very sturdy, as sturdy as the watch itself.

NEGATIVES
1.  This watch is a bit large and heavy for me.  With my small wrists and large hands, the watch rubs against my lower hand and my wristbone.  I got it primarily for triathlon training, and this problem would be exasperated by my arm movement when I run.
2.  Don't buy this watch unless you plan to spend 30 minutes reading the manual.  It's different than every other watch I've ever owned, such as the start/stop of the watch being on the bottom right instead of the top right, and clear being vice-versa.  You have to tell it what time zone you live in.  The alarms are downright crazy; the four regular alarms don't have a snooze feature, and the snooze alarm requires pushing a button about four times to finally turn it off (if you want it off before the every 5 minutes for 30 minutes window is up).
3.  The tiny dials are practically worthless, as they are so small they require a lot of effort to read.
4.  To save on battery power, the light is only on for a split second, which means you usually have to hit the light button twice, which negates any battery-saving power.
5.  The buttons are hard to push, since they are recessed, which makes the watch more bullet-proof, I guess.  Forget about being able to push the buttons wearing gloves, as it's hard enough to push them with your bare fingers.

I love knowing my watch is showing the exact time, but the solar function is overrated, I think.  After all, most watch batteries last 10 years, then you might as well just buy a new watch.

Overall, the uncomfortableness of the watch prompted me to send it back, even after I had mastered the entire manual and how much I like how it looks.  I can completely understand how so many people love the watch, but it just wasn't for me.
