    Wouldn't it radioactivate you or something???

    Cesium is a stable isotope and is not radioactive. The only problem I see with a wrist watch containing Cesium is accidentally jumping in the pool with it or being caught in the rain.

    I don't get it... Would it make a chain reaction???

    No. It would make a perfectly normal, everyday exothermic chemical reaction.
