Color: all black watch
It’s not an ugly watch, but I did not think the watch looked as nice in person This watch lost several minutes over a few months. It is light and feels cheap. However, it was not expensive, it’s comfortable to wear and beauty is in the eye of the beholder.

The band is hollow and the watch doesn’t feel well built
Color: gold watch for men
Cheaply mad, I purchased a expensive watch and it’s nice but the cheap one is definitely what you pay for will not buy or recommend to anyone
