Forgive me if I use the wrong terminology here - when I was setting the timer, the hour hand was moving, and the minute one was not. The hour hand would push the minute one a bit as it passes by it. By doing this, the hour hand actually fell off its position and is no longer attached. It is stuck in the watch face, and my watch is currently unusable as the minute hand cannot be set and the hour hand is completely detached. I have not mishandled this watch in any case. In fact, I have got a watch case where I stored it everyday. I would appreciate the help. It is a GM-503-4 with a date of "30-12-2019" on the card.
