Awesome.
Color: Silver Blue Brown
Loved it! I can hardly hear it run, its so quiet! It's very easy to read and looks quite classy. The leather strap has also held up very well to normal wear.

A Great Value for the Time
Color: Rose Gold Black
Beautiful watch that looks far more expensive than it is. The rose gold finish is very attractive, and the black faux leather band goes well with it. It tells time accurately. The only caveat is the date window which is so tiny that it's very difficult to read when not under direct light. I am very pleased with my purchase.

Nice watch!
Color: black/black
This watch was very easy to set and keeps time very well. It looks great with a professional appearance it seems to be well built and the warranty is good. The glass on the first one I got cracked after two months and they are sending me a new one!

Great value!
Color: black/black
Great value for the money. My teenage son started a watch collection, and this was the perfect addition. It looks like it cost a lot more than it really did.
