I have a lot of extracurricular activities, including boxing, karate, jujutsu, aikido and so on. I often study for 10 hours straight for law school, with periodic breaks on the punching bag or so on. Obviously, you wouldn't want to wear a watch in an actual fight (if it could be avoided) or particularly in grappling, but sometimes I just want to jump up and do forms or work the bag. I can easily throw my 80 lb bag back with a simple left jab, so I know the energy being put through there is pretty intense. I actually imagine the bagwork will be easier on the watches since it doesn't have the sudden stop of makiwara practice or shadow boxing.
Sometimes I forget to take my watches off--thank God I've never forgot to take a mechanical off--before taking a practice break. But I've wondered if even an ordinary quartz could handle the impact. I bought my g-shock so I could wear a stopwatch that didn't get in the way when I'm teaching class without worrying about breaking it (more because it's so cheap than because I think it can handle it--so far, no problems).
What say you, high impact sports people. Is this a recipe for disaster? Or is it acceptable to wear my quartz watches for bag/no bag punching drills.
The g-shock will get worn at any rate, since that's why I own it--I suppose I ask this question because I have my first "nice" quartz watch, my Citizen Grand Complication, and I'm worried about breaking it by forgetting to take it off.
