I've had this watch for 3 years and it's been back to Tissot twice. The first time, they kept it for 3 months, sent it back, and within 6 hours it had quit working again. The second time, they kept it for another 4 months and then sent me a new one.  The problem is that it stops working completely if I'm wearing it.  I can take it off, put it on the desk, and it will start working again within an hour and keep working for weeks--until I put it on.  Then, within a few hours, it's completely 100% punk dead again.  Take it off--fine. Put it on--garbage.  I'm beginning to think I'm haunted because everybody I know who has one swears by it. But for the same thing to be happening to me each time I wear this watch, and on two different watches? I've been wearing Seiko watches my entire life, battery powered AND self-winding; never had a problem. But this Tissot and I just don't seem to have the right "chemistry."  I'm wondering if this has happened to anybody else...  I even went on the internet and found a few people claiming that battery-powered watches won't work on people who've had near-death experiences.  That'd be interesting if I'd ever had one, but I haven't. The watch is gorgeous, the functions are amazing, it's way cooler than a Rolex, a Breitling or a Tag, but the freaking thing just won't work on my wrist!
