I knocked the second hand off a Casio quartz while digging post holes with the old fashion, long handle kind of diger. The second hand gave me about a day free before it jambed the minute hand, which jambed the hour hand and brought the works to a grinding halt. A few $ at the mall watch repair station, "--- oh, and a new battery, please, whileyou are in among the guts," and it was good to go. However, I don't wear it anymore when digging post holes.
