Was the ETA 2821 the only automatic movement the Ball RR wrist watches used? I've found two watches that have the ETA 2822 movements installed. They are calendar movements with the calendar parts removed. I thought the first one was a fluke or fake, but now I found another one. They both have the "Ball" labeled rotating weight. I've also found one with a ETA 2632 movement installed. I guess I've been snookered. Let the buyer beware.
