Good watch, nice large numbers.
Color: Black
Nice watch. Not illuminated, but luminous hands and dial are easy to read at night. Day/date display is easy to adjust but must avoid doing so between 5PM and 9AM. Seems to be very accurate so far and time is fairly easy to synchronize. No problems with scratched crystal so far, and I wear this watch 24/7. Very long band should fit any size wrist.

POS
Color: Silver
Its just junk.. Quit working within 3 months of purchase. Took it apart and nothing looked bad, put in a new battery and still nothing. I didn't expect much considering the price, but you're practically throwing money in the trash buying this. Costumer service is non-existent if you're looking for a replacement. Amazon will always give money back with a returned item.

Most satisfying purchase in years!
Color: Silver
I bought this watch as part of the Black Thursday Deals. I didn't expect much frankly, but I've been mightily impressed by its quality and utility. As a timepiece and as an accessory, this is a great buy. The face is easy to read, the second-hand sweeps exactly on the second marks (a rarity these days in even fairly expensive watches) and it keeps good time (one second per day fast so far). The day/date are a good size and pretty easy to set using the industry standard crown-pull method. The brushed aluminum case appears durable and yet it's comfortable. The strap is thin but of good quality; it has 13 holes and will fit a wide variety of wrist sizes. Overall, I'm totally satisfied and have no hesitation in highly recommending this outstanding watch.

Solid, if basic, cheap watch.
Color: Black
This is a solid, if basic, quartz watch. It keeps good time, and the NATO strap is comfortable. Though some have had complaints about it's waterproof rating, I've had no issues with that. But... The lume (glow-in-the-dark) is pretty weak and doesn't last long. I expected that, but it actually bothers me more than I thought it would. The date window is small and hard to read; which is fine because a month after I got it, it lost the ability to change the date (April has 30 days, but I can't skip over the 31st to the 1st) If I cared about the date function, that would be a deal breaker.
