Working on a #116 movement, pictured below. The click "clicks" but isn't holding the gear in place; when you let go of the crown it immediately unwinds / lets down. Almost identical to 104 design, and a lot like the 24.
I don't know what a #116 click is supposed to look like; there's only a single piece of spring steel (unlike the #24, which is a plate design.) I haven't cleaned it yet... not sure it would help.
Case is square and 2 part; a gold-colored outer and a chrome inner that pressed in. Crystal and seal was held between the two halves. Has a dime-sized case back that allows you to pull the stem, then the movement removes from the front. Since the case splits, no need for a crystal lift.
