Simple, affordable, smartly styled. Good starter watch for teens
Color: Black
Got this for 13-year-old boy for Christmas. Excellent choice for a beginner's watch. Learn to read a clock face for crying out loud! Easy to set the day/date, and has a comfortable band.

Style classic
Color: Silver
A neat watch, I was a career soldier and I remember getting a few different military style watches, mostly made by Timex. I was in supply so had access to them, often the style was the same and sometimes not.
Item was packed well and arrived fast great price

Decent watch for the price - you get what you pay for
Color: Black
This watch is about what I expected for the price. It's comfortable to wear and is keeping time reasonably well thus far. Illumination on the hands and dial fades after a couple of hours and setting the day of the week does not work (it will not advance - day just sort of "bounces" in the window - although the day changes on its own). Given the reviews I read, I take it off before showering and avoid getting it wet when washing my hands, as I don't trust the water resistance.
EDIT: After posting the generally positive review above, the seller messaged me offering a replacement on their own initiative and allowing me to keep the original watch. I did not expect that but accepted their offer. Upon receiving the replacement, I discovered that the problem setting the day of the week was user error and not a problem with the 1st watch. My only criticism of the watch remains that the illumination fades within an hour or two (I held it next to a 150W lamp bulb for 30 seconds) but I am willing to live with that and believe the watch is a good value. I increased my rating from 3-stars to 5-stars on the strength of the great customer support and what I think is the value proposition for a very comfortable, easy to read, $20 watch. I would buy again.

Almost great
Color: Black
Watch is well made, and has mineral crystal, not plastic. It fits nice and is comfortable. The bad is that the watch has virtually no luminous qualities and the day and date is hard to read. Other than that it is a great value if you can get by with the small characters on the watch face. The crown is not screw down and can occasionally pull out so the time changes

Good little watch, bear in mind the price point that it is at that though.
Color: Black
The design I love. It’s minimal, not flashy, but good looking all around. It is a matte black finish, which looks pretty good. The glass definitely seems to be scratch resistant in the first couple days I’ve been wearing it. not 100% precise with setting the time with the dial, but after a couple times, I got it to be right on point. It has stayed on time the last couple days. However, if you look at the price point of this item, it is cheap. The material does feel high-quality, not made of the Chineseium that you’d find on crap these days. The date and day of the week, however, seem to be stuck, and some of the days that I saw by manually reversing the hands were misspelled. If you’re not bothered by those things, this seems to be a good watch for the money. Just keep in mind it’s not perfect.
