3135 date not working

[trueblackpercula]

hello everyone just changed the main spring on a 3135 and everything seems to be working as the main spring was broken in two pieces. so after changing it the watch now is keeping time and working, so i thought..... i placed the watch in an automatic watch winder for two days and this morning it had the correct time but the date did not change. I than proceed to pull out the stem to the last position and i was able to change the date and set it. i than turned the hands around the dial to stimulate 12midnight and the date still does not change. any suggestions would be greatly appreciated

as always thank you
Michael
