Pros:

-cheap, accurate watch--seriously, for less than 20 bucks it's hard to beat
-waterproof
-big, visible time
-dual time feature
-super bright Indiglo

Cons:

-will leak if you push buttons underwater
-confusing, vague instructions
-cannot disable beep (or if you can I can't figure out how)
-weird date display
-flimsy strap

What do you expect for less than 20 dollars price point? Got this as a "throwaway" watch for traveling--in case I lost/broke it. Turns out it's very good for everyday use, comfortable to wear, and has big, easy to see numbers. The Indiglo is great in the dark, and the alarm is decently loud if you're not a heavy sleeper.

DO NOT try to operate it underwater, for some reason the switches stop being waterproof when you push them in.
