I am wondering what kind of tool is necessary to remove the movement from a Longines Admiral wristwatch. It states on the back of the case use wrench 1260. The bezel popped off but nothing else came off. The back of the case is solid so this movement must come out through the front. Wonder what a wrench 1260 looks like and does it unscrew the area under the crystal? Can anyone help. Pictures enclosed.
