It is very nice, I have many watches, but this one is the main one I use for casual wear. One thing I do not like: After about two days of either use or not use, the time gets off, by a couple hours but you can put it back pretty easily. And the "day display" on the watch never stays correct due to the fact that every month doesn't have 31 days in it. But other than that, it is a great watch for show, not to keep track of time.

Money Well Spent

Color: Silver Face Brown Band-G8408

I love this little watch, I can count on it every time one of my $10,000 watches stops working. The thing just sits in the drawer and waits for me, I was going to give it to a small child as a gift. I changed my mind only because it's good to know I have a dependable watch somewhere. I guess I'll have to pay attention to the battery at some point but I will change the battery and not just toss the watch..

A little disappointed.

Color: Silver Face Brown Band-G8408

The watch looks good but it stops running at times and if I move it around it starts back up. Been running okay for over a week now. Band is not as nice as it looks in the pictures, cheap looking. Will work for now.
