Some markers are "press fit" into the dial, some use adhesive.
Any rough handling of the watch case can cause a marker to come loose and fall onto the dial.
A good watchmaker can remove the caseback, then remove the movement from the case.
After evaluating what is required to replace and secure it, the movement is put back into the case and the caseback tightened.
No big deal but do it soon before the loose marker gets jammed under a moving hand...
Good luck with your watch.....
Been there, done that!
