Going to say off the bat that I am new to this site, so, if I am posting this in the wrong forum, I apologize. Regardless, I recently purchased a pocket-watch online and it came in today. When I took it out I ended up accidentally starting it. I tried to figure out how to stop it ( I figured that I should be able to by pulling the crown, as in a regular watch), and it did just that but the second hand kept moving. I spent 10 more minutes trying to figure it out. But I gave up and soon decided I might as well adjust the pocketwatch's time to the correct time. This time, however, I have no idea why, but the time wouldn't adjust when I was twisting it. So, I carefully pulled a bit more. But I kept on finding that the time wouldn't adjust anymore for some reason and noticed the crown was reacting differently and I soon noticed it was pulled off. I can easily put it back in but it still remains loose and will fall out easily, but still somehow managed to open the pocket watch when I press the crown still.
