Great watch.
Color: silver/brown
This watch is impressive. Perfect timekeeping, comfortable on the wrist, easy to read and lightweight without feeling flimsy. Considering the price it’s a remarkable watch.
I don’t know about durability, time will tell, but I am impressed so far. I sincerely hope that it lasts, because I like it very much.
I field style watches are your thing, you should not hesitate. Get it.

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.

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.
