Counts the grinding motions when using a manual coffee grinder.

Tested wearing the watch on the left wrist holding the coffee grinder in the left hand and the crank lever in right.

In principle it counts circular movements in the X-Y plane but uses only the X-accelerator data to detect the motion. In testing the frequency was about one circular motion per second.
