About Product:1.

If the battery ages, the user can be notified in advance to replace the battery.

Hard to set day/date.
Color: A-Black
Watch very professional looking and appears to be well made. Everything about this watch is what I have been looking for at a reasonable price. The only issue I have is how to set the watches features, time, date, and day. The instructions are very clear and well written, to a point. That point being the instructions say to move the "crystal" to the first notch, to adjust the day/date, and the second notch for to set the time. What the instructions fail to mention is the day/date adjustment must be turned a full 24 hours to the next day or date settlings. Also, trying to hit just the second notch is almost impossible as the is no distinct way of knowing if you are in it or not,

Big face, easy to read.
Color: A-Green Luminous
Great watch ! Large face and hands makes it easy to read,
Backface glows in dark if enough light is exposed to it.
Showered a few times, no problem. Will hit the waves later this week.
Update on that later.
Very happy with purchase and seller. Can recommend.

Good price
Color: A-Green Luminous
I bought a return. It was 5 bucks cheaper.
It looks nice and wears well.
I like the color and material.
I did have a little issue with setting the date. The day is in English and Chinese. That's a first, lol. It's usually in English and Spanish.
It would be a nice gift for a youngster to learn military time.

Broke within first 3 month
Color: B-Green 2
I wore it for work due to no clock and not being able to look at phone on the clock. Instead of relying on managers to tell me the time and so on I bought this. Was quite reliable until I dropped it a few times then one day I could only tell time through the minute hand. Had to replace it with a digital because I do not trust a mechanical one at the moment due to this. Also the glow barely worked, it'd glow but not bright enough to tell time and not for long. I'd say I guess you get what you pay for although it should withstand dropped better internally. Durability sucks and comfort was there.

Nice looking, but Will Not Keep Time!
Color: C-Black Luminous 2
This is my second watch from this company. This was a different style! The first one ran perfect for 3 years! So I brought another one. This one, out of the box was slow. I changed the battery, still, slow! I even brought a second one from them, it too is running slow.
