As Advertised
Color: 5535-HP-white
The watch is what I expected, and works upon receipt as advertised. At this price, if it only works for 4-6 months it's easily worth the money. Large, nice looking face, day/date. Wristband is what you'd expect, but adequate and comfortable.

Dies after a Year
Color: 5566-ZP-white face
Watch worked fine for about a year, then just stopped working - just like that. No amount of shaking or gentle impacts would get it to start ticking again. I'd also say my biggist issue with it was it was always difficult to tell which hand was the second hand and which hand was the minute hand since they're both the same color and thickness. Wish the hour and minute hands were a little thicker so they'd stand out a little better and/or that the minute hand was a different color so it was offset. Resulted in having to study the watch to get the time instead of a quick glimpse to see what time it was. Irritating after a while.
