How do you adjust a puritan watch day hand?

I had the same problem until I discovered the watch has a two position knob. Pull the knob all the way out, (careful not to go too far!) and you can adjust the date...1,2,3 etc. After setting the correct date push the knob all the way back in and then carefully with the slightest touch pull the knob out just part way. If you are carefull enough you will feel a click as the knob settles into this first position. Then turn the knob and you will be able to adjust the day of the week. Then push the knob back in and you are all set.
