Rman, thanks for your question. I did a little more research and found this reference on the C11KAS movement. It's a great reference to check on other watch movements.
My Wittnauer SC Diver was serviced in 2013 so it should work as spec'd. Quick set date function works by changing the crown at 4 from 19:30 to 24:00 ... and it works beautifully!
