You get what you pay for
Color: 6692:Silver strap&blue dial
I thought I'd give this a try but when I took it out of the box, it was the cheapest built watch I ever bought. You get what you pay for. It was supper light so I don't believe it was stainless wrist band. Felt more like potted metal. Never again.

My every day watch. I love it.
Color: Silver/Black/Gold
Is it the nicest watch? Nope. Does the clasp come undone as time goes on? Yep. Do I still wear it every day? Absolutely. This is my daily driver watch. It will win no awards in quality or style, but it looks great, goes with everything, has minimal error as days go by, and is easy to read. Cheap and great. A rare combo these days.
