Very stylish but not the best quality
Color: Silvery Gold green dial, Color: Silvery Gold green dial
You are getting what you pay for: the color of the dial is amazing. It looks so stylish and can really accessorize an outfit. The packaging of the watch was very nice and it came with tools to adjust the size of the watch. However the links color is not the best color and quality. The watch feels light but in a cheaper feel. I’ve ordered other watches from Amazon that in my opinion were nicer and felt and looked high end. I got this watch on sale for Black Friday but I’m not sure if I would pay full price for it.
