Excellent Watch
Color: Gold Silver-G8408
I don't know why this watch is getting a less than perfect rating from others. I purchased this watch legit to make sure my son got out of the shower at the gym on time to get where he is going. LOL It is classy, elegant and yes, has been exposed to sweat, water and soap extensively, and still looks fantastic. He is getting the black one next.

looks good but is unreliable; replacement coming
Color: Gold Blue-G8408
Update: The company reached out to me and offered me either a refund or a replacement watch. I bumped my rating up by two stars for that good customer service, and I'll provide another update once I have the replacement and see how it works.
This watch looks great, was a good price, and I enjoy wearing it. The problem is that it keeps stopping. An unreliable watch is a big problem. Unfortunately, I was out of the country and didn't get to return it in time before the return window closed. If it worked properly, I would have given it a five-star rating.
