Worst watch I have ever purchased!
Color: 2858-Silver Gold-Black Face
The rods in between in each link aren’t solid rods at all! They’re made up of almost long, thin staples that bend and break EXTREMELY easily. Taking them off is incredibly difficult to begin with! I’ve removed links on hundreds of watches, it’s not my first rodeo, it has never been this ridiculously difficult due to extremely cheap materials. I wish I could give this a negative 100, never seen a cheaper watch. It’s extremely light and looks nothing like the picture either. Seriously, don’t waste your time. It’s the worst, cheapest watch you can buy. I shouldn’t expect better from Amazon.

Nice looking but horrible clasp design
Color: 2858-All Black-Black Gold
Nice watch. The only bad thing is the clasps on the wrist band is horrible. One little bump and it opens up and then you have to try to catch the watch in case it completely falls off. I'd recommend only buying this if you are willing to change the wristband out otherwise half the time you will be fighting it from opening up and slipping off.

Best watch for 40 bucks
Color: Blue Face/Silver Strap, Color: Blue Face/Silver Strap
Works well, tells time, bang for your buck. People are complaining about esthetics and breaking after a while. You're spending 40 bucks on a watch what do you expect? Cmon. Its good for the price buy this one if you want something cheap, functional, and stylish.
