Have to agree with many of the colleagues here...an excellent and informative post. It is nice to see the science behind the facts that many of us know...don't believe the hype and do your research. Here are a couple of things I know...
A job needs a specific tool. If I were a serious diver, I would get a serious diving watch (I had a Luminox once. Are they a great diving watch?) that would overly compensate for the gravity (pun...yuck:-x) of the task.
For the things I do (which at my age are becoming much tamer), a GShock is actually overkill. I work out with weights, boat, fish, bicycle, shoot pictures, hike, swim, body surf, and any other number of more mundane around the house tasks. The list used to include many other things from working on cars to manual labor and a GS has always come through with flying colors. Hats off to Casio for this little slice of Heaven on earth.
