Impressive, especially at this price point.

Color: black/black

Feels & looks like a Timex Expedition- which fills with water in the shower, fogs on himid days. This is a fraction of the cost and functions as advertised.

Such an amazing watch

Color: silver/black

Beautiful look, no noise. The brightness on the glow and the dark portions are amazing during the night. It feels like a hundred dollar watch while being so cheap and affordable. Lightweight and easy to wear. I’ve done a lot of hard work with this watch and there isn’t a scratch on it.

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.
