I've only reviewed approx. a dozen (12) LED wristwatches prior to this, so please bear with me here. 
You might remember LED wristwatches from the 1970s, heck, you might still have one.
The Luxury Men's Fashion LED Digital Watch (hereinafter, probably called simply an, "LED watch" or an, "LED wristwatch") is an LED watch that features a large display comprised of seven-segment LED "readouts"
It can display the time & date like other digital watches, it also displays seconds if you require that feature, and it has a plastic band.
SIZE
The LED wristwatch comes ready to use right out of the bag. You may need to set the time & date - but is otherwise ready to go right away.
To read the time, press & release the button on the upper right of the watch's side. The time will be displayed for three seconds, then the LEDs will automatically extinguish.
To read the date, press & release the button on the upper right of the watch's side, the date will be displayed for three seconds, and then the LEDs will automatically extinguish.
To read the seconds, press & release the button on the upper right of the watch's side, the seconds will be displayed for three seconds, and then the LEDs will automatically extinguish.
The display will remain on (from beginning to end) for 3.27 seconds (timed with a stopwatch)
I haven't yet figured out how to change the battery when it becomes necessary, so this section of the web page will remain vacant for the time being.
Because this is a watch and not a flashlight, I won't try to flush it down the poddy, stomp on it with old or used bowling shoes, viciously throw it into one of those wall-mounted porcelain uranators to see if it becomes broken (the uranator, not the wristwatch), smack it against a steel rod, run over it with my Quickie motorised wheelchair, or perform other potentially destructive tests on it that might be performed on a flashlight.
This watch is said to ***NOT*** be waterproof, so you'll want to be careful around sinks, tubs, toliets, and other sources of water, and you'll have to take it off before showering or bathing.
As a wristwatch, I think it's quite nice. And to see real live LEDs in it, that's even better. 
I love LEDs and things made with them, and this watch is no exception.
The display isn't very bright (however this will equate to longer battery life!); if you work outdoors and prefer LED wristwatches to analogue or LCD watches, you may wish to use a different LED watch with a significantly brighter display.
