Yes, It is called a "switch arbor." Rockford made, I think, 3 versions of this 18s watch with a switch arbor. It didn't work very well and most of the time when you find these watches now, the mechanism is broken and it is stuck in one mode or the other.It is supposed to change the setting mechanism to lever set or pendant set.
Hey nuno,Hello my friends,
Thanks the information. My watch is working. In this case is better not clean the watch? What you think?
