Good watch
Color: Silver/Green
This actually a good watch for the price. It glows in the dark due to solar exposure during the day. The wrist band was a little long for my first.

No complaints, attractive, good work horse of a timepiece.
Color: Black/Green
Works great. I gave the luminous face a couple hours under a table lamp. When I went for my nightly half hour walk it glowed green the entire trip. Did not dim out like other watches with luminous hands/digits. So I know it glows for more than half an hour. My 2nd watch from this manufacturer. The other is an infantry watch OD green. Had it for 4 years daily use and still runs great. Changed the batt once. Could not see it in the dark at all. So, this new purchase for nights. I recommend it.

Love This Watch...!
Color: Black/Green
Waiting for a delivery of an expensive diving watch and in need of a watch for my sporting needs, I opted for this as an interim fix. However, it more than filled my need! Nice to look at! (Several compliments received.)
Best part is the watch has not lost even 1 second after 3 weeks on my wrist. Never expected that level of accuracy!!
While the current band suits the watch's appearance, an upgraded band would fool many into thinking it was far more expensive.
Great watch to gift to a buddy...!
I would categorize this as a "Best Buy"!

Great timepiece!
Color: Silver/Blue
This is a cool watch! I collect many different styles & price points of watches. There is nothing not to like about this watch. The dial, strap & completely luminous dial make it a great time piece. It's a smart looking field watch that lays nicely on the wrist. $20 is an amazing bargain for this watch. Highly recommend!
