My father gave me this watch that used to belong to my grandfather, I need to remove some links to fit my wrist, but I can’t figure out which direction the pins are supposed to be pushed out. I couldn’t find any arrows to to indicate the direction, can they be pushed out either direction or is there some way to determine which way they should be pushed out? I’m planning on ordering a watch tool kit to do it myself, but don’t want to risk damaging anything. Any advice would be appreciated!
