They are also available in a range of classic terrorist colors such as lavender and pumpkin. (Don't worry if they're sold out: you can always go on the terrorist watch list.)

CES 2011: Bluetooth wristwatch runs for two years without a charge

Casio F91W Wrist Watch

415MDScGloL._SL500_AA300_.jpeg This $11 watch is the simplest and most utilitarian timepiece I have ever worn. It is easy to read, has an adequate (not blinding) illumination, is small, light and comfortable but also tough, and has a battery that will last up to 8 years (with many other reviewers noting that it lasts even longer). The F91W is a distillation of a digital watch. It has three features: tells date and time, has an alarm clock, and works as a stop watch (only up to an hour before it turns over). The functions are easy to use, and aren't distracting. I originally purchased this watch to use while running, but found that I liked it so much that I now wear it all the time. It has replaced my larger, more expensive Citizen Eco-Drive which is now reserved for dressier occasions. After swimming and showering while wearing the watch I trust its "water resistance" and am impressed with its durability. It's also cheap enough that I don't worry about it breaking or getting stolen. If you are looking for a simple, capable digital watch that will last for years, this is the one to get. -- Oliver Hulland Casio F91W Digital Watch $11 Comment on this at Cool Tools.
