  1. I had this problem as well. I believe the cannon pinion is slipping when extra power needed at day date change. It's not like the cannon pinion on Seiko automatics. You need to tighten the wheel on the tube but be careful the wheel spokes are super fragile. This movement is also a PITA the date wheel has to be 100% flat and the teeth true or the date quick set will jam and the date will also not sit right in the window after changing.
  2. Is there not a plastic I-ring or L-ring you are missing to press the crystal into?
  3. Open back up and recase, the pusher is not against the brass tang and is getting stuck. No spring in these just the pressure from the brass lever. If very stiff the rubber o ring will need in the pusher will need a grease or if hardened replaced.
  4. Crown gasket EB0070BB Caseback gasket FH2930B01
  5. Hairspring looks bunched to the left in second photo. Does the train run freely without the pallet fork? Did you clean the mainspring and clean and oil the diashock jewels?
  6. If hands feel loose when setting and stop before date change then look at the cannon pinion. It need a very delicate squeeze. Others will chime in with links and how to do this correctly I'm sure. Good luck.
  7. You might find you need to solder these parts together. It might get messy with the plastic if you don't have a pointed tip!
  8. This may help https://www.thewatchsite.com/21-japanese-watch-discussion-forum/1677-crystal-codes-seiko.html
  9. Interesting. Have you tried the crown and stem in the serviced watch outside the case? Is it still difficult to pull out?
  10. Cousins do have them it's part number 015.713
  11. Drilling it out might be your only option. Slowly is the word to use here when drilling. Maybe a dose of ultrasonic cleaner might help. Final solution another case off ebay.
  12. You would first have to push out old crystal and measure it as citizen part numbers don't give any anything as to what size it is unlike Seiko p/n. You could then see if you crystal is available as a sapphire in the measured size. I have to say Citizens crystals are often weird sizes.
  13. As above rodabod just beat me to it! Its more likely to be the second hand has enlarged. You need to close the hole up a little. Easier said than done. The lip on the hand needs to be tightened. Must be some info on here on how to do it properly rather than my bodge.
  14. Could be a few things. Is it stiff when changing the time if so it's the cannon pinion too tight. The day or date wheels are buckled or more likely the the date drive wheel or day finger is bent and catching.
