NOT WORTH IT
Color: E All Black
Not worth the money in my opinion. Very light weight. Almost like wearing a child's watch. Cheaply made.

Beautiful, luxurious-looking watch.
Color: Grey
Beautiful, luxurious-looking watches. Impeccable craftsmanship. Highly polished glass & reflective hour markers & arms pop with a luxurious shine in the light. Love these watches. So much so I have bought several in different color faces for different occassions. Each is beautiful. Finely detailed minute, hour & second hands are easy to read even in dim light. Outstanding quality for the price. Perfect size looks great on the wrist & keeps accurate time. I have had more compliments of these watches, than much more expensive watches I have.

Cheap not worth the money
Color: Blue
You get what you pay for and most of these cheap watches from China that you get on Amazon aren’t worth the time you spent ordering them off the site. I bought like six of them as gifts and none of them lasted more than a month
