Okay, Iβve spent too much time thinking about this. You really donβt want the watch.
For the watch to work, everything must stop. I assume that you can (hypothetically, more on that later) move anything without any more resistance that you normally would have, or else the first thing that would happen would be that air molecules would shred you like a cheese grater.
Then it occurred to me that you would potentially be in trouble if you stayed in one place for more than a minute or so, as carbon dioxide would quickly build up around your mouth. Least of your problems, of course.
If everything stops, that includes electromagnetic radiation. Otherwise digital and atomic clocks continue, computers keep working (and counting time), anyone sitting down for a minute outside when you click the button gets a sunburn, or if they are looking near the sun or a reflection of it they are now blind. Instead, you are now blind, as light rays are no longer streaming through your environment, bouncing off of things, and reflecting into your eyes. You can kind of see by moving your head forward and effectively impaling frozen light rays on your retinas, but you have to keep moving constantly forward to get any kind of stimulation, and of course leave a wake of no light behind you where things are perfectly dark should you reenter.
Thatβs not really a problem, though. The vibration of atoms has stopped. This means the temperature outside of your magically disconnected body has now dropped to exactly 0Β° Kelvin. You freeze to death almost instantly. This finally is a good thing, because it prevents you from experiencing what happens next.
Now, many forces are probably no longer in operation, but gravity probably is, since it is more analogous to a distortion of space-time than an active force (assuming mass-giving subatomic particles impart that mass by presence rather than flow). However, since weak electrical force is generated by electron motion, objects no longer resist being passed through. Though they themselves do not move, trapped in time, no longer do they restrain you from the Earthβs gravity, and you plummet towards Earthβs center, where the gravitational force alone squeezes you into the size of a pea, along with the watch.
