I was in the market for a new watch recently, and I stumbled upon Casio's line of watches that automatically sync to the NIST radio signal.  A problem I was having with my previous watch was that I kept having to set the time because its mechanism was wound by motion, and I didn't wear it over the weekend.  Having a watch with the wrong time is worse than having no watch at all.  So I bought one of the Casios, and so far so good. 

I liked the idea so much, I bought a little bedside alarm clock with the same functionality.  Knowing my clocks are always synced to the right time is a good feeling. #products
