Fashionable and Affordable
Color: black/black/green, Color: black/black/green
Watch face is very readable and strap is comfortable. Glass has yet to be scratched and I work a blue collar job. Fantastic watch for the price, keeps accurate time too.

A great versatile watch
Color: black/black
This is a great watch. I wear a Rolex GMT daily, but wear this at the gym, at fencing practice, holding power equipment , hammering and other activities. Runs fine, keeps good time, easy to read. Like the 24 hour dial. Sometimes I just wear it because I like it.

Good watch, not incredibly durable for everyday use.
Color: silver/brown
A nice watch, the date feature and the glow in the dark were quite helpful. It lasted be about 6 months of regular use. Unfortunately it stopped keeping time (intermittent freezing) and the second hand fell off, I'm kinda disappointed with its durability. Unsure of the initial cause, I guess I hit something with my wrist.
