Hi, this 1976 Accutron arrived in the mail today. I have a couple of questions. Should the small 3 pointed piece to the right of the watch be loose like that? From a google search it looks like this sits underneath the battery, is there a trick to how it should be placed? Also, the battery strap doesn't have a screw for the loose end. Does it just slide under the edge of the black cover? Any advice would be greatly appreciated. The movement number is 2191.10 if that helps at all.
