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.

What time is it? Time to buy this watch!
Color: Blue
This is a great watch at an unbelievable price. You get quality materials, durable construction, reliability and style, all for a great price. I wear this watch more than my others, and I have quite a few, but this one has that "it" factor. I get a lot of compliments on it and love the aesthetic. It keeps time well and has a pretty long battery life. The fit is also great too since it very adjustable.

Good value
Color: Black
Surprisingly good watch at this price. Compatible with common 20mm NATO straps. Have worn mine extensively despite owning more expensive field watches. Got the black model and switched to a Bond NATO strap. Good legibility, light but not cheap feeling. Lots of great affordable field watches out there from Timex, Militado, Addiesdive, etc, but at the sub $20 price I think this is one of the best values.

Semi-tough and inexpensive
Color: Blue
I purchased this watch because I needed one that I could put into harms way without hesitation; I also needed it to survive. Inexpensive and semi-tough. A tall order. So far so good! Bonus points for appearance. Color coordination and it looks pretty good, lightweight and adjustable for the cost of three gallons of gasoline!
