If you have to ask, probably not.
Either the crown unscrewed from the stem (remove caseback, release stem, screw crown back onto stem, reinstall stem) or the stem broke (replace stem) or the stem release in the keyless works got bent & it can no longer lock the stem in the movement (disassemble the keyless works, find/fix the problem, reassemble). If you post a good, clear close-up pic of the part of inside of the crown, I can tell you more (refer to the 'Macro' section of your camera's manual).
