Not sure if the crown has snapped off or just come out. Have tried putting back in without success. Any ideas? Also what model is this watch? Thanks
Looks like the part of the stem snapped. To fix it you need to take the rest of the stem out (there should be a button or screw that releases the other half of the stem) and then put in a new stem. Shouldn't be too hard of a job for a good watchmaker. Good luck!
