Well you clearly missed the point. I didn't say the word impossible, because its not impossible. The chances are just so astronomically low that it won't matter how much you shake the box. Say there are 50 parts in the watch (which is a simple watch BTW). That means each part has a 1/50 chance of fitting back where it needs to (for simplicity's sake). According to probability, each pieces chances must be multiplied with the other ones. So, 1/50 * 1/50 *1/50...... And so on eventually get you the odds of 1.1258999e-85, which is 1.1258999 preceded by 85 zeros. Is it technically possible? Sure. Technically anything is possible. Is it [i]actually[/i] possible? No.
