This watch is very rugged. I have owned several of these in the past 15 or so years. None have actually broken, except the straps. I usually wear the writing off of the watch and put a couple of new batteries in them before the rubber strap eventually breaks. I am very hard on them, as I wear it 24/7, unless I am dressing up and put on my Tag Heuer. I can't say that I use the stopwatch much, but it does work perfectly.
