Around a year ago Dewey posted pics of a 992B with gouges carved from the gold screws. I thought of that when cleaning this watch for a friend: a 4992B. Someone went to town on nearly all the screws. When replacing the staff, he scratched an arrow on the balance arm to show the stud position. Most odd, though, is the collet. It looks like most of it has been roughly carved away. I'm not sure what would cause someone to do that. Sigh... Are these the sorts of things the military watchmakers did when trying to quickly turn-around a watch, or is this just another example of bad work in general?
