It's pretty quiet here on the lab. Most students finished their Personal Experiments and now it's waiting for the new Profile Experiments. I took a bunch (33) G-Shock's with me, so I could set them in a free hour. I needed only 1 battery to refresh. You got to pay attention a lot to how you set your watch (some were many minutes fast, since it is over 1 year I did set my watches).
I ended just a fw minutes before 13:00, so I thought I should make a movie of the hour signal, just for fun. For me the big beep is a conformation I have set the watch on the right minute. Here's the movie:
P.S. I have not the right Flash player on this computer, but I assume the movie is viewable on most computers.
