I bought the black one. It's pretty cool. It doesn't look as cheap as the colored ones.
I wear it with whatever I'm wearing. I recently wore to a corporate meeting with a nice suit on on and it matched pretty good. I get compliments on it because it's pretty unique. Unique, New York, unique, New York.
I'd give it 5 stars but the following led me not to:
If you wear it on your left wrist, and you bend your wrist (picture putting your hand flat like you would if you were walking on your hands) it presses in the two right buttons simultaneously which turn the hourly alert beep on (or off). Kinda annoying.
It's about 1 1/8 inch square face.
Backlight works well.
