What Would Happen if I Threw My Watch into a Black Hole?

AI Thread Summary
If a watch is thrown into a black hole, it appears to slow down as it approaches the event horizon, eventually seeming to halt from the observer's perspective. Light from the watch becomes redshifted and fainter until it fades from view, although the watch continues to cross the event horizon without the observer ever seeing it. The black hole gains mass equivalent to that of the watch as it falls in. The discussion emphasizes that while the watch appears to stop, it actually crosses into the black hole, highlighting the effects of extreme gravity on time perception. Ultimately, the watch's fate illustrates the complex nature of black holes and their impact on light and time.

You don't see the watch fall and the clock work.

that what i want to hear!
 
Your watch will appear to slow as it approaches, and virtually halt by the time it reaches the event horizon. Photons emitted, or reflected by the watch face can no longer escape the intense gravity of the black hole.

and when it's infall does seem to have virtually halted to you, it will keep showing virtually the same time to you,
but light from it will get redder and redder until it is no longer detectable.
It will apparently fade away into non existence.
 
It ticks (as measured by you) slower and slower, you see it redder and fainter, getting closer and closer to the horizon but never crossing it. In reality it crosses the horizon, no problem, you will just never see it. And so the black hole gets heavier by the mass of a watch.

The watch will start to slow once it approaches the black hole and as it enters the black hole the watch will stop.

So many people answered the question and there is no reason to bump the thread. Let this be the last.
