I was fiddling around with my Citizen Blue Eagle (pic on Watcharama http://www.watcharama.com/ct005.htm if you want to see something like it, but mine has blue dial with irregular arabics) and noticed that, although it doesn't hack in the normal sense, if you turn the hands backwards when setting the time, the seconds hand stops, and stays stopped until tension is released. I'm not sure if this is a design feature or a design accident or a production flaw, but it does allow the time to be set with some accuracy.

The movement is a bog standard Miyota 8200, generally advertised as manual winding but non-hacking. Does anyone know if all 8200 movements do this, and if so whether doing it is likely to wreck the movement?
