Hi all I'm new to the site, but really glad I came across it! I've off and on amassed the parts needed (all genuine) to assemble a geneve dynamic with a 1012 movement. What I don't know is if there's a spacer needed between the underside of the dial and the inside of the case or if the movement simply rests in the recess and the plexi crystal holds the dial and movement snugly in place on its own. Many thanks in advance for the help. Andy
