I have beautiful Citizen Gold Tone E870 PP Eco Drive Watch, which was running perfectly well until I opened up and tried to replace the crystal. I did not touch anything on movement, but after putting stuff together, everything works OK (like Time, L-TM, ALM etc.) but some how the Date and the multi-function dial (for Leap Year, DST & Day indicator) stop working. Watch is fully charged and I tried to ALL RESET many times, but the Number "3" on Date and the Multi-function sub-dial's hand does not move at all. Any suggestion or help in trying to diagnose and fix the issue. This is my one of the favourite watch and dammmn....this happened, and I am really looking for some tips/guidance to bring back the missing functionality20200607_170702.jpg20200607_170130.jpg of the CALENDAR.
Thx you all in advance for your help, support, time and guidance.
