I do hard construction work, and have destroyed a lot of good watches (smashing, scratching, catching, and forgetting to take them off before running the jackhammer).  This little plastic Timex, which cost $16 back then, is amazing. I bought 2 of them because they were so cheap and so I would not be without a watch when the first one broke. The other one is still sitting in my drawer unused.  This watch is all scratched up, and I have replaced the watchband several times, but it is still has the original battery, is still waterproof and extremely accurate.  One of the greatest features is its light weight. You don't even feel it is there, and I think the light weight and thin dimension help keep it from being damaged.
