Damn...
now I'm going to sound doh
Try moving it thru the three crown positions, one (winding pos), two (date pos), three (time setting pos) and forward time in pos 3 so it changes date a few times.
set time to anywere between 3pm and 9pm
push in to pos 2, change quick date a few times
push in to pos 1, wind it gently a few times
pull out back to pos 2 set date to yesterday
pull out to pos 3, rotate until date rolls over to today, and set proper time (keep in mind am/pm)
push all the way in, rotate back and forth alittle, back-space towards you until you feel click, then with inward pressure rotate away from you til it catches and screws- in.
Didn't work again, is it a quartz rep? Not scew-down?
Sorry if it doesn't work...stripped?
Anyone else care to take a stab at it?
Link to where you got it, would help in identifying movement
